For overall water-splitting systems, it is essential to establish O2 -insensitive cathodes that allow cogeneration of H2 and O2 . An acid-tolerant electrocatalyst is described, which employs a Mo-coating on a metal surface to achieve selective H2 evolution in the presence of O2 . In operando X-ray absorption spectroscopy identified reduced Pt covered with an amorphous molybdenum oxyhydroxide hy...

Due to the contamination and global warming problems, it is necessary search for alternative environmentally friendly energy sources. In this area, hydrogen a promising alternative. Hydrogen even more promising, when obtained through water electrolysis operated with renewable Among possible devices perform electrolysis, proton exchange membrane (PEM) electrolyzers appear as most commercial syst...

Electrochemical water splitting, as a promising method for hydrogen production, has attracted significant attention. However, the lack of an electrocatalyst with small energy loss and fast reaction kinetics hindered development this technology. Amorphous nanomaterials short-range order long-range disorder features have recently shown superior activity compared to their crystalline counterparts ...

Since the discovery of the Honda-Fujishima effect of water splitting[1] using a titanium dioxide (TiO2) electrode in the early 1970s, numerous studies have been conducted and are still growing on photocatalytic reactions of TiO2. Titanium dioxide serves as a model case for the mechanistic studies of photocatalysis, but it has a serious drawback as a photocatalyst for water splitting: the band g...
