Regulating the coordination capacity of ATMP using melamine: facile synthesis of cobalt phosphides as bifunctional electrocatalysts for the ORR and HER

Abstract

Due to the complexity of the synthetic process of cobalt phosphide (CoP), ongoing efforts concentrate on simplifying the preparation process of CoP. In this work, amino tris(methylene phosphonic acid) (ATMP,...

MnS-MoS2 Nanosheets Supported on Mo Plates as Electrocatalyst for the Hydrogen Evolution Reaction

“…As shown in Figure b, MnS-MoS 2 /LA-Mo requires an overpotential of 85 mV to drive the current density of 10 mA cm –2 , lower than those of other comparable Mo-based electrocatalysts. The obtained overpotential of MnS-MoS 2 /LA-Mo is also much lower than those of many reported nonprecious metal-based electrocatalysts, as shown in Figure g and Table S1. − Figure c displays the Tafel slopes of various electrocatalysts. It is seen that MnS-MoS 2 /LA-Mo shows a low Tafel slope of 42.9 mV dec –1 , which is much lower than those of the other Mo-based electrocatalysts and close to the value of Pt/C (28.7 mV dec –1 ).…”
