This paper is focused on the photocatalytic hydrogen production Pd/TiO 2 (-WO 3 ) catalysts from water-methanol and water-glycerol mixtures under UVA solar irradiation. The photodeposition method for Pd was studied varying conditions such as amount, catalyst concentration methanol concentration. were tested at lab scale simulated light radiation also large (25 L) energy using a pilot-scale Comp...

Metal/semiconductor hetero-nanostructures are now considered as benchmark functional nanomaterials for many light-driven applications. Using laser-driven photodeposition to control growth of gold nanodots (NDs) onto CdSe/CdS dot-in-rods (DRs), we show that the addition a dedicated hole scavenger (MeOH) is cornerstone significantly reduce less than 3.5% multiple-site nucleation and 2.5% rate gol...

BiVO(4) semiconductor electrodes were coupled with cobalt-phosphate complexes (CoPi) to enhance the photoelectrochemical (PEC) performance for water oxidation reaction. CoPi was deposited on a 550 nm-thick BiVO(4) film via electrodeposition (ED) and photodeposition (PD) methods for comparison of their effects. The CoPi on BiVO(4) exhibited Co : P atomic ratios of approximately 1 : 7 for the ele...

Octahedral anatase particles (OAPs) were prepared by hydrothermal (HT) reaction of titanate nanowires (TNWs). OAPs were modified with noble metals (Au, Ag, Cu and Pt) by two photodeposition methods: in the absence and in the initial presence of oxygen in the system. Photocatalytic activities for oxidative decomposition of acetic acid and anaerobic dehydrogenation of methanol under UV/vis irradi...

Commercial titania photocatalysts were modified with silver and gold by photodeposition, and characterized by diffuse reflectance spectroscopy (DRS), X-ray powder diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and scanning transmission electron microscopy (STEM). It was found that silver co-existed in zero valent (core) and oxidized (shell) forms, whereas gold was mainly zero valent....

This work presents a comparative study of the efficiency two commercial TiO2 photocatalysts, Aeroxide P25 (ATiO2) and Sachtleben Hombikat UV100 (HTiO2), in H2 production from an aqueous solution naphthalene. The photocatalysts were platinized by photodeposition method varying platinum content suspension to 0.5, 1.0, 5.0 wt%. A full physicochemical characterization for these materials was perfor...

A simple, alternative, catalyst preparation method was proposed in order to combine the properties of photoactive and stable TiO2 with state-of-the art IrO2 for oxygen evolution reaction (OER). nanoparticles were obtained process photodeposition on surface powder by UV illumination from appropriate Ir salt aqueous solution. Physicochemical characterization resulting IrO2/TiO2 composite, contain...
