Heterostructuring cobalt sulfide with highly oxophilic 1T-tungsten sulfide for durable and efficient oxygen electrocatalysis

Abstract

First row transition metal sulfides are one of the most promising platinum group metal free catalysts toward oxygen electrocatalysis, while their structural and compositional changes during catalysis result in the...

Electric field-induced phosphorization to prepare CoP@Biochar composites for efficient bifunctional oxygen electrocatalysis

“…In recent years, non-noble metal materials have been developed to improve the catalytic performance of the OER and ORR, such as transition metal sulphides, 12 carbides, 13 borides, 14 nitrides, 15 etc. Among them, transition metal phosphides (TMPs) [16][17][18] (TM = Fe, Co, Cu, Ni, W and Mn) have gained attention owing to their rich resources, suitable d-electron configuration, and abundant chemical states.…”

Heterointerface enhanced NiFe LDH/V–Co4N electrocatalysts for the oxygen evolution reaction

“…[15][16][17][18] In addition, the construction of heterointerfaces is another efficient way to optimize the performance of electrocatalysts. [19][20][21][22] The strong interfacial interaction among different species is utilized to adjust the electronic structure of surface sites, optimize the adsorption energy of oxygenated intermediates and improve the kinetic and thermodynamic characteristics of the OER. [23][24][25][26][27] For example, G. Sun and co-workers reported amorphous-crystalline nickel borate-nickel sulde (Ni 3 (BO 3 ) 2 -Ni 3 S 2 ) heterostructures, which effectively enhanced the chemisorption of oxygen intermediates.…”
