Electrocatalysis through interface and structural engineering of hollow/porous NiSe/CoSe2 nanotubes for overall water splitting

Engineering hierarchical snowflake-like multi-metal selenide catalysts anchored on Ni foam for high-efficiency and stable overall water splitting

“…13,14 In particular, transition metal selenides exhibit excellent electrocatalytic activity in water electrolysis under alkaline conditions due to their outstanding electrical conductivity and antioxidant capacity. 15,16 However, the single component selenide material may still have insufficient active sites and poor stability, which will affect the actual electrocatalytic performance. 17,18 Therefore, it needs to be further modified to improve its electrocatalytic activity and stability.…”
