A Highly Active and Robust CoP/CoS2-Based Electrocatalyst Toward Overall Water Splitting

Nanoneedle-Assembled Copper/Cobalt sulfides on nickel foam as an enhanced 3D hierarchical catalyst to activate monopersulfate for Rhodamine b degradation

“…The Co2p spectrum displayed in Fig. 6(b) shows several noticeable peaks can be detected at 778.0 and 781.1 eV, which correspond to Co2p3/2 and at 794.1 and 797.0 eV, which correspond to Co 2p1/2; these peaks collectively suggest the presence ofCo2+ [35]. The S2p spectrum was then analyzed (Fig.…”

“…The S2p spectrum was then analyzed (Fig. 6(c)) and two underlying peaks were found at 162.0, and 163.1 eV, corresponding to S2p3/2 and S2p3/2, respectively [35]. Fig.…”

Recent advances in transition metal phosphide-based heterostructure electrocatalysts for the oxygen evolution reaction

“…49,50 The synthesis of TMP/TMS heterostructures typically involves a two-step process that includes sulfurization–phosphorization or phosphorization–sulfurization of metal/oxide/hydroxide precursors, or a one-step process that involves phosphorization and sulfurization of metal/oxide/hydroxides. For example, Pan et al 51 synthesized an electrocatalytic CoS 2 CoP/CC via a hydrothermal–phosphorization–sulfurization method, as shown in Fig. 4(A).…”

Hydrogen-etched CoS2 to produce a Co9S8@CoS2 heterostructure electrocatalyst for highly efficient oxygen evolution reaction

“…Therefore, reasonable selection of active ingredients with heterostructures, and their ideal degree of combination can control the overall electrocatalytic performance to a large extent. The coupling of CoS 2 or Co 9 S 8 with additional excellent electrocatalytic materials such as CoP, 32 2p 1/2 (793.6 eV) of Co 2+ . In addition, due to storage and other reasons, the samples are exposed to the air to produce Co-O bonds, which correspond to 781.4 eV and 797.7 eV.…”
