Developing low-cost and highly active electrocatalysts to replace Pt group metals is very critical the hydrogen evolution reaction (HER). Transition-metal carbides (TMCs) have drawn broad attention as potential HER catalysts in recent years due platinum-like electron structure. This review highlights strides on synthesis routes optimization strategies of TMC electrocatalysts, discusses future p...

We report conductance and thermopower measurements of metallic atomic-size contacts, namely gold and platinum, using a scanning tunneling microscope (STM) at room temperature. We find that few-atom gold contacts have an average negative thermopower, whereas platinum contacts present a positive thermopower, showing that for both metals, the sign of the thermopower in the nanoscale differs from t...

Due to the toxicity of beryllium compounds, the chemistry of beryllium is far less developed than that of its neighboring elements [1, 2]. As berylliumcontaining materials feature unique properties, most of the corresponding research is done in material sciences [3]. With regard to its toxicity, additional work is focused on the coordination chemistry of Be(II) in aqueous solutions [4, 5]. Thus...

This manuscript reviews the current trends in recovery of Platinum Group Metals (PGMs) from end-of-life autocatalysts and aims recently funded Marie Sklodowska-Curie Project “Chemistry Metals-CHemPGM” towards greening PGMs processes reusing recovered for preparation new catalysts. Together with analysis state art spent through pyrometallurgical hydrometallurgical routes recent reducing their en...
