Rational design of highly active electrocatalysts for the oxygen evolution reaction (OER) is critical to improving overall electrochemical water splitting efficiency. This study suggests hollow CeO2@Co2N nanosheets synthesized using Co-ZIF-L as a precursor, followed by hydrothermal and nitridation process very attractive OER catalysts. The increased activity supposed be due strong electronic in...

In this paper, we present the results of processing metallic gallium in an ammonia vapor medium at 2 bar pressure by femtosecond laser pulses. The influence concentration and mode beam scanning on result action is considered. It has been established that increase a change regime lead to radical ablation process. A decrease speed leads cessation process development nitridation surface, accompani...

In this work the n-GaN(1000) surface is used as a source of nitrogen atoms in order to obtain niobium nitride film by surface-mediated nitridation technique. To end, physical vapor deposition on GaN followed sample annealing at 1123 K. A thermally induced decomposition and interfacial mixing phenomena lead formation compound, which contains Nb from thin N substrate. The processes allowed obtain...
