چکیده

We report the first use of cobalt aluminophosphate (CoAPO5) as a water oxidation catalyst. A decrease in the overvoltage by about 0.2 V with respect to catalyst free FTO has been observed. Additionally, we show that CoAPO5, deposited on ITO or Pt, can also act as a photo-electro-catalyst, as it generates enhanced oxidation currents in the presence of light starting from a bias of +0.8 V vs. Ag/AgCl.

Visible light-driven water oxidation with a subporphyrin sensitizer and a water oxidation catalyst.

A new subporphyrin was synthesized for use as a molecular sensitizer in electrochemical and dye-sensitized photoelectrochemical water oxidation. A photoelectrochemical cell with a TiO2 electrode modified with the sensitizer and a molecular water oxidation catalyst generated higher photocurrent than reference cells that have electrodes modified with either the photosensitizer or the catalyst und...

Bidentate dicarboxylate capping groups and photosensitizers control the size of IrO2 nanoparticle catalysts for water oxidation.

Dicarboxylic acid ligands (malonate, succinate, and butylmalonate) stabilize 2 nm diameter IrO2 particles synthesized by hydrolysis of aqueous IrCl(6)2- solutions. Analogous monodentate (acetate) and tridentate (citrate) carboxylate ligands, as well as phosphonate and diphosphonate ligands, are less effective as stabilizers and lead to different degrees of nanoparticle aggregation, as evidenced...

Photovoltage Effects of Sintered IrO2 Nanoparticle Catalysts in Water-Splitting Dye-Sensitized Photoelectrochemical Cells

Water-splitting dye-sensitized photoelectrochemical cells (WSDSPECs) utilize high surface area TiO2 electrodes functionalized with light absorbing sensitizers and water oxidation catalysts. Because water splitting requires vectorial electron transfer from the catalyst to the sensitizer to the TiO2 surface, attaching both sensitizer and catalyst to TiO2 in the correct sequence and stabilizing th...

Dynamics of Electron Recombination and Transport in Water- Splitting Dye-Sensitized Photoanodes

Water-splitting dye-sensitized photoelectrochemical cells (WS-DSPECs) use visible light to split water using molecular sensitizers and water oxidation catalysts codeposited onto mesoporous TiO2 electrodes. Despite a high quantum yield of charge injection and low requirement for the catalytic turnover rate, the quantum yield of water splitting in WS-DSPECs is typically low (<1%). Here we examine...

Aliphatic alcohols oxidation with Hydrogen Peroxide in water catalyzed by supported Phosphotungstic acid (PTA) on Silica coated MgAl2O4 nanoparticles as a recoverable catalyst

In this paper, a novel catalyst (MgAl2O4@SiO2-PTA) was proposed for the green oxidation of aliphatic alcohols. The resultant composite was characterized by different techniques, such as X-ray diffraction (XRD), SEM, FT-IR, EDX and Brunauer-Emmett-Teller (BET) surface area analysis. The prepared nanocomposite was used as a catalyst for oxidation of aliphatic alco...
