The conversion of solar energy into fuels and, specifically hydrogen, is a critical process for ensuring the sustainability future system. Among different ways converting and chemicals, photoelectrochemical tandem cells, containing two photoactive materials, stand out as they have potential direct solar-to-fuel conversion, thus minimizing cost. implementation photoelectrolysis hydrogen generati...

An overview on processes that are relevant in light-induced fuel generation, such as water photoelectrolysis or carbon dioxide reduction, is given. Considered processes encompass the photophysics of light absorption, excitation energy transfer to catalytically active sites and interfacial reactions at the catalyst/solution phase boundary. The two major routes envisaged for realization of photoe...

In this study, polyol-made CdS and CdSe crystalline nanoparticles (NPs) are loaded by impregnation on TiO2 nanotube arrays (TNTAs) for solar-simulated light-driven photoelectrochemical (PEC) water vapor splitting. For the first time, we introduce a safe way to utilize toxic, yet efficient photocatalysts integration in solid-state PEC (SSPEC) cells. The enabling features of SSPEC cells surface p...

The degradation of paracetamol in aqueous solutions in the presence of hydrogen peroxide was carried out by photochemistry, electrolysis and photoelectrolysis using modified 100 pores per inch reticulated vitreous carbon electrodes. The electrodes were coated with catalysts such as TiO(2) and CuO/TiO(2)/Al(2)O(3) by electrophoresis followed by heat treatment. The results of the electrolysis wit...

Mesoporous tungsten trioxide (WO3) was prepared from tungstic acid (H2WO4) as a tungsten precursor with dodecylamine (DDA) as a template to guide porosity of the nanostructure by a solvothermal technique. The WO3 sample (denoted as WO3-DDA) prepared with DDA was moulded on an electrode to yield efficient performance for visible-light-driven photoelectrochemical (PEC) water oxidation. Powder X-r...

The photoelectrolysis of water to yield hydrogen and oxygen using visible light has enormous potential for solar energy harvesting if suitable photoelectrode materials can be developed. Few of the materials with a band gap suitable for visible light activation have the necessary band-edge potentials or photochemical stability to be suitable candidates. Tungsten oxide (Ebg 2.8 eV) is a good cand...

This paper studies the applicability of a novel microwave-prepared mixed metal oxide (MMO-Ti/RuO2IrO2) anode in electrolysis and photo-electrolysis synthetic urine intensified with Penicillin G. Results are compared those obtained using boron-doped diamond (BDD) as anode. In general, both anodes effective terms penicillin removal, combination UV radiation shows clear synergistic effect on degra...

The disposal of hospital wastewaters, particularly urine with high concentrations pharmaceuticals, is a critical problem. These pharmaceuticals can enter the environment and lead to development superbacteria (in case antibiotics) due inefficiency conventional treatment these aqueous wastes. Hence, this report focuses on scale-up photoelectrochemical (PEC) system equipped Ru-based mixed metal ox...
