Abstract
Transition metal selenides constitute a family of materials used for multi-electron charge transfer reactions (e.g. hydrogen evolution reaction, oxygen reduction reaction) in which activity, selectivity, and tolerance are required. Here we review the engineering of such structures focused on the selenization process of nanoparticulate precious metals supported or not on carbon. The chemical/electrochemical process of selenization proceeding through a so-called soft chemistry route, in which each species (cationic, anionic) interacts under conditions dictated by the solvent medium, is briefly described. The electronic effect of the synthesized materials subjected to the modification effects leading to undefined and/or defined phases (via chemical coordination) of the surface of the metallic atoms is reviewed.
期刊介绍：
The development of the Current Opinion journals stemmed from the acknowledgment of the growing challenge for specialists to stay abreast of the expanding volume of information within their field. In Current Opinion in Electrochemistry, they help the reader by providing in a systematic manner:
1.The views of experts on current advances in electrochemistry in a clear and readable form.
2.Evaluations of the most interesting papers, annotated by experts, from the great wealth of original publications.
In the realm of electrochemistry, the subject is divided into 12 themed sections, with each section undergoing an annual review cycle:
• Bioelectrochemistry • Electrocatalysis • Electrochemical Materials and Engineering • Energy Storage: Batteries and Supercapacitors • Energy Transformation • Environmental Electrochemistry • Fundamental & Theoretical Electrochemistry • Innovative Methods in Electrochemistry • Organic & Molecular Electrochemistry • Physical & Nano-Electrochemistry • Sensors & Bio-sensors •
