Hollow Bimetallic Cobalt-Based Selenide Polyhedrons for Efficient Hydrogen Production in Practical PEM Electrolysis

“…In the Ni 2p spectra (Figure S8b), the peaks observed at 857.33 eV (Ni 2p 3/2 ) and 870.71 eV (Ni 2p 1/2 ) can be attributed to the presence of Ni 2+ . Additionally, there is a satellite peak detected at 860.77 eV, which corresponds to multielectron excitation, and an oscillating peak observed at 876.71 eV (Ni 2p1/2) . The Co 2p spectra (Figure f) exhibit distinct peaks at 779.64 and 796.08 eV, corresponding to the Co 2p 3/2 and Co 2p 1/2 states of Co species present in CoSe 2 .…”

Furthermore, the observed peaks at 777.06 and 792.44 eV can be ascribed to the existence of amorphous oxide layers on the surface with Co−O bonding structures.…”

Advanced Microwave Strategies Facilitate Structural Engineering for Efficient Electrocatalysis

“…[79] Through meticulous adjustments to the catalyst structure, the synthesis of high-performance electrocatalysts characterized by low overpotential, favorable Tafel slope, and extended service life becomes achievable. [80][81][82] This methodological precision contributes to the exacting control of the electrocatalytic process, thereby culminating in a comprehensive enhancement of performance.…”

3D Porous Biomass Derived Carbon Composite Modified with (Ni,Co)Se Particles for High‐Performance Supercapacitors

“…However, compared with metal oxides, transition metal selenides have higher theoretical charge storage capacity and abundant crystal structure, [29] and have been proved to show excellent properties as electrode materials. Nickel-based (NiSe, [30] NiSe 2, [31,32] Ni 3 Se 2, [33] etc.) and cobaltbased selenides (CoSe 2, [29] CoSe, [34] Co 0.85 Se, [35] Co 9 Se 8, [32] etc.)…”
