RE-doped (RE = La, Ce and Er) Ni₂P porous nanostructures as promising electrocatalysts for hydrogen evolution reaction

Abstract

The construction of an efficient non-noble-metal electrocatalyst towards alkaline hydrogen evolution is challenging, but in great demand. Fabricating the porous nanostructure and heteroatom doping are two productive strategies to develop...

(FeMnCe)-co-doped MOF-74 with significantly improved performance for overall water splitting

“…Dalton Therefore, the introduction of the Ce element can effectively reduce charge-transport impedance and improve the electron transfer rate, thereby promoting electrocatalytic kinetics. As reported in previous literature, [67][68][69][70][71] rare earth elements can effectively modulate the electronic structures and reduce the H* absorption energy, further promoting HER activity. In a word, the above comparative results of the EIS test further demonstrated the importance and effectiveness of the 3d-4f mixed metal strategy.…”
