R.L.F was responsible for conceptualization, data curation, methodology, investigation concerning HER testing and writing the original draft.…”

“…13−15 The introduction of a heterointerface seems to be a very good strategy for surface engineering. 16 Indeed, at the interface of two components, a spontaneous electron transfer activated by the heterostructure can modify the electronic state of the surface and improve the catalytic performance. 17 In addition, the lattice strain and electron injection at the interface can tune the catalytic activity.…”

“…However, much work remains to be done to achieve a high current density at low overpotential. Since the electrolysis of water takes place on the interfaces or surface of the catalysts, surface engineering is very important to boost the HER. − The introduction of a heterointerface seems to be a very good strategy for surface engineering .

Industrial-scale efficient alkaline water electrolysis achieved with sputtered NiFeV-oxide thin film electrodes for green hydrogen production

“…Notably, sputtering yields self-supported, firmly adherent films that mitigate the peeling-off problem encountered under high current densities. 16 For instance, the innovative approach of Z. Qi et al 17 was successfully used to develop heterostructured Ni/Ni 3 N thin films through precise adjustments to the plasma environment during magnetron sputtering. The sputtered Ni/Ni 3 N electrocatalyst, enriched with interfacial sites, demonstrates exceptional HER performance, requiring a low overpotential of 37 mV at 10 mA cm −2 and maintaining stability over 100 h in an alkaline solution.…”

Sputtered binder-free Cu3N electrode materials for high-performance quasi-solid-state asymmetric supercapacitors

“…This binder-free technology enables the use of harmless N 2 instead of toxic NH 3 gas, remarkable uniformity, high purity, and excellent adhesion of Cu 3 N to substrates. 23 Jiang et al fabricated Cu 3 N thin films by magnetron sputtering at different gas flow ratios and acquired superior photocatalytic activity. 24 Nevertheless, there are few studies concerning the application of magnetron sputtered Cu 3 N in SCs, and the lack of comprehensive investigation still prevents a deeper understanding of its energy storage behavior.…”
