Manipulation of oxygen evolution reaction kinetics of a free-standing CoSe₂–NiSe₂heterostructured electrode by interfacial engineering

Abstract

Electrodeposition is a facile and scalable strategy to prepare free-standing OER electrodes with promising electrocatalytic activity, high active site utilization, and fast mass transportation. In this study, hierarchical CoSe2-NiSe2 heterostructured...

Synthesis and Electrocatalytic Applications of Layer‐Structured Metal Chalcogenides Composites

“…Rauf and co-workers synthesized layered CoSe 2 /NiSe 2 compounds for OER, which showed the overpotential of 310 mV at 10 mA cm −2 in 1 m KOH. [222] Qi and co-workers prepared a series of CoTe 2 /NiTe 2 /CoNi composites via a facile method, the optimized CoTe 2 /NiTe 2 /CoNi composites showed a low Tafel slope (19.4 mV dec −1 ) and a low overpotential (280 mV@10 mA cm −2 ) for OER in 1 m KOH. [219] In this part, the different types of LMCs-based composites for OER have been summarized, and these studies have confirmed that such LMCs-based composites are excellent materials for electrocatalytic oxygen evolution.…”
