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.
在本信函中，我们报道了基于阴离子交换反应，通过氢氧化镍前驱体的拓扑转变，在碳布上水热生长二硒化镍纳米壁膜（NiSe₂ NW/CC）。当在强酸性介质中作为集成的三维析氢阴极进行测试时，NiSe₂ NW/CC表现出优于其粉末对应物的出色催化活性和强大的长期耐久性。它在过电位分别为145和183 mV时，电流密度分别达到10和100 mA cm⁻²，其催化活性可保持40小时。
