Enhancement of ZnO@RuO bifunctional photo-electro catalytic activity toward water splitting.

Catalytic materials are the greatest challenge for the commercial application of water electrolysis (WEs) and fuel cells (FCs) as clean energy technologies. There is a need to find an alternative to expensive and unavailable platinum group metal (PGM) catalysts. This study aimed to reduce the cost of PGM materials by replacing Ru with RuO and lowering the amount of RuO by adding abundant and multifunctional ZnO.

Structural and Chemical Properties of Geopolymer Gels Incorporated with Neodymium and Samarium.

The present work was focused on doping of 1% and 5% both of NdO and SmO in geopolymer gels. One of the main goals was to determine the influence of the behavior of Nd and Sm as dopants and structural nanoparticles changes of the final geopolymer formed. It is shown that the disorder formed by alkali activation of metakaolin can accommodate the rare earth cations Nd and Sm into their aluminosilicate framework structure.
