Near-complete suppression of surface recombination in solar photoelectrolysis by “co-Pi” catalyst-modified W:BiVO4

The influence of an earth-abundant water oxidation electrocatalyst (Co-Pi) on solar water oxidation by W:BiVO4 has been studied using photoelectrochemical (PEC) techniques. Modification of W:BiVO4 photoanode surfaces with Co-Pi has yielded a very large (?440 mV) cathodic shift in the onset potential for sustained PEC water oxidation at pH 8. PEC experiments with H2O2 as a surrogate substrate have revealed that interfacing Co-Pi with these W:BiVO4 photoanodes almost completely eliminates losses due to surface electron-hole recombination. The results obtained for W:BiVO4 are compared with those reported recently for Co-Pi/alpha-Fe2O3 photoanodes. The low absolute onset potential of ?310 mV vs RHE achieved with the Co-Pi/W:BiVO4 combination is promising for overall solar water splitting in low-cost tandem PEC cells, and is encouraging for application of this surface modification strategy to other candidate photoanodes.

Oxidovanadium(V) complexes containing hydrazone based O,N,O-donor ligands: Synthesis, structure, catalytic properties and theoretical calculations

Two new mono oxidovanadium(V) complexes, [VOL1(OEt)] (1) and [VOL2(OMe)] (2), of the tridentate Schiff base hydrazone-type O,N,O-donor ligands H2L1 and H2L2, obtained by monocondensation of 3-hydroxy-2-naphthohydrazide with 5-bromo-2-hydroxybenzaldehyde and benzoylacetone, respectively, have been synthesized starting from VO(acac)2 [H2L1 = (E)-N?-(5-bromo-2-hydroxybenzylidene)-3-hydroxy-2-naphthohydrazide; H 2L2 = (E)-3-hydroxy-N?-((Z)-4-hydroxy-4-phenylbut-3- en-2-ylidene)-2-naphthohydrazide]. Single-crystal X-ray structure analysis revealed for both complexes a slightly distorted square-based pyramidal NO 4 coordination environment around the metal centre, with the aroylhydrazone Schiff bases acting as O,N,O-tridentate, dinegative ligands. The complexes were also characterized by spectroscopic methods in the solid state (IR) and in solution (UV-Vis, 1H NMR) and by cyclic voltammetric experiments in DMSO, and their properties were interpreted by means of DFT theoretical calculations. The catalytic potential of these complexes has been tested for the oxidation of thioanisol using H2O2 as the terminal oxidant. The effects of various parameters, including the molar ratio of oxidant to substrate, the temperature and the solvent, have been studied. Both complexes showed superabundant catalytic activity in the oxidation of thioanisol at room temperature with excellent conversions.

Dual Modification of a BiVO4 Photoanode for Enhanced Photoelectrochemical Performance

Bismuth vanadate (BiVO4) has triggered extensive interest in photoelectrochemical (PEC) water splitting, owing to its narrow band gap and sufficiently positive valence band. However, some defects still exist to block the solar utilization efficiency and hydrogen evolution kinetics. Herein, the NiMoO4 semiconductor is combined with a BiVO4 photoanode, for the first time, and excellent PEC performance is achieved on the basis of heterojunction formation and favorable conductivity of NiMoO4. In addition, it has been demonstrated that NiMoO4 promotes the light absorption ability, charge separation efficiency, and surface charge-transfer efficiency comprehensively. To further improve the photoconversion efficiency, cobalt phosphate, as an oxygen evolution reaction cocatalyst, is deposited on the above electrode and achieves a much enhanced utilization efficiency of 1.18 %, with a photocurrent density of 5.3 mA cm?2 at 1.23 V versus a reversible hydrogen electrode; this exceeds most results reported to date. This rational and unique photoanode construction provides a new thread for the photoelectrode designation.

Three novel Ni(II), VO(II) and Cr(III) mononuclear complexes encompassing potentially tridentate imine ligand: Synthesis, structural characterization, DNA interaction, antimicrobial evaluation and anticancer activity

Three novel Cr(III),VO(II) and Ni(II) imine complexes derived from the condensation of 2-aminophenol (AP) with 2-hydroxynaphthaldehyde (HN) were synthesized. The prepared HNAP imine ligand and its complexes were investigated via various physicochemical tools. The results suggest that the parent ligand behaves as a dibasic tridentate ONO ligand, when coordinated to Cr(III) in octahedral and to Ni(II) in tetrahedral geometry. In the case of VO(II), it coordinates in distorted square pyramidal geometry. Also, the prepared compounds were screened for their antimicrobial activities against pathogenic bacteria, Escherichia coli (?ve), Bacillus subtilis (+ve) and Staphylococcus aureus (+ve), and some types of fungi, Aspergillus niger, Candida glabrata and Trichophyton rubrum. The results indicate that the complexes show a stronger antimicrobial efficiency compared to the pro-ligand. The interaction of the prepared complexes with calf thymus DNA was investigated using spectral, viscosity and gel electrophoresis measurements. The obtained results clearly demonstrate that the binding affinity with calf thymus DNA follows the order HNAPCr > HNAPV > HNAPNi. The cytotoxic activity of the prepared compounds on human colon carcinoma cells (HCT-116 cell line), hepatic cellular carcinoma cells (HepG-2cell line) and breast carcinoma cells (MCF-7cell line) was examined. From these results it is found that the investigated complexes have potent cytotoxicity against growth of carcinoma cells compared to the corresponding imine pro-ligand.

Density functional theory calculations of the electron paramagnetic resonance parameters for VO2+ complexes

Density functional theory calculations of electron paramagnetic resonance (EPR) parameters, such as electronic g tensors and metal hyperfine interaction (A) tensors, have been completed for a series of VO2+ complexes. g tensors were calculated with the zeroth-order regular approximation (ZORA) for relativistic effects as incorporated into the Amsterdam Density Functional (ADF) program. The A tensors were calculated by relativistic and nonrelativistic methods as implemented in ADF and Gaussian98 programs, respectively. The best overall agreement with experimental A values was obtained with the nonrelativistic method and the half-and-half hybrid functionals, such as BHPW91, BHP86, and BHLYP. The isotropic A values (Aiso) calculated nonrelativistically with the BHPW91 functional deviated by about 10% from the experimental Aiso values. The Aiso values calculated with the relativistic effects and pure generalized gradient correction (GGA) functionals, such as BP86, deviated systematically by approximately 40% compared to the experimental Aiso values. The difference in performance of the two methods for these complexes is attributed to the improved performance of hybrid functionals for treating core shell spin polarization. The calculation of the anisotropic or dipolar hyperfine interactions, AD, was less sensitive to the choice of functional, and therefore, the relativistic and nonrelativistic calculations of AD exhibited comparable accuracy.

Oxidation of carbon monoxide cocatalyzed by palladium(0) and the H 5PV2Mo10O40 polyoxometalate probed by electron paramagnetic resonance and aerobic catalysis

The H5PV2Mo10O40 polyoxometalate and Pd/AI2O3 were used as co-catalysts under anaerobic conditions for the activation and oxidation of CO to CO 2 by an electron transfer-oxygen transfer mechanism. Upon anaerobic reduction of H5PV2Mo10O40 with CO in the presence of Pd(0) two paramagnetic species were observed and characterized by continuous wave electron paramagnetic resonance (CW-EPR) and hyperfine sublevel correlation (HYSCORE) spectroscopic measurements. Major species I (65-70%) is assigned to a species resembling a vanadyl cation that is supported on the polyoxometalate and showed a bonding interaction with 13CO. Minor species II (30-35%) is attributed to a reduced species where the vanadium(IV) atom is incorporated in the polyoxometalate framework but slightly distanced from the phosphate core. Under aerobic conditions, CO/O2, a nucleophilic oxidant was formed as elucidated by oxidation of thianthrene oxide as a probe substrate. Oxidation reactions performed on terminal alkenes such as 1-octene yielded a complicated mixture of products that was, however, clearly a result of alkene epoxidation followed by subsequent reactions of the intermediate epoxide. The significant competing reaction was a hydro-carbonylation reaction that yielded a ?1:1 mixture of linear/branched carboxylic acids.
