title: Highly efficient electrochemical hydrogen evolution based on nickel diselenide nanowall film.
abstract: In this letter, we report on hydrothermal growth of nickel diselenide nanowall film on carbon cloth (NiSe2 NW/CC) through topotactic transformation from a Ni(OH)2 precursor based on anion exchange reactions. When tested as an integrated 3D hydrogen-evolving cathode in strongly acidic media, NiSe2 NW/CC exhibits outstanding catalytic activity superior to its powder counterpart and strong long-term durability. It displays 10 and 100 mA cm(-2) at overpotentials of 145 and 183 mV, respectively, with its catalytic activity being retained for 40 h.
