“…In Fig. 6 (a), low cell voltages of 1.57 and 1.69 V are achieved to afford water splitting current densities of 10 and 100 mA cm −2 , respectively, better than recently reported advanced electrocatalysts such as CoP nanowires on Co foam [16] , Co 3 Se 4 /CF [44] and Ni 3 S 2 /NF [45] . It is notable that the current density exhibits no noticeable deterioration after conducting continuous water splitting at 1.57 V for over 58 h ( Fig.…”

“…and cubic pyrite‐type or orthorhombic marcasite‐type TMDs (e.g., CoS 2 , CoSe 2 , NiS 2 , FeS 2 , etc.) . Owing to the moderate hydrogen binding energy or the partially filled E g band, these TMD materials usually display high intrinsic HER activity.…”

“…This result indicates that the Ni in the material is mainly in the two valence forms of Ni 2+ and Ni 3+ , which proves the existence of NiS 2 . The mutual conversion between valence states can provide a large tantalum capacitance, providing an excellent basis for electrocatalysis with N‐PECVD …”

“…The mutual conversion between valence states can provide a large tantalum capacitance, providing an excellent basis for electrocatalysis with N-PECVD. 38 In this part of the experiment, the electrochemical performance of a N-PECVD electrode, prepared by PECVD in 0.5 M H 2 SO 4 and 1 M KOH. To complete a comprehensive test, we tested an electrode prepared by chemical vapor deposition, named N-CVD, as a control test to demonstrate the benefit of the PECVD method in the preparation of the electrocatalyst.…”
