With hydrogen fuel becoming a more viable alternative to fossil fuels comes the need for inexpensive, low-energy hydrogen production. Here, a low-temperature direct solution-processing method is presented for the deposition of earth-abundant pyrite-type NiSe as an efficient hydrogen evolution reaction (HER) catalyst. Thin films of phase-pure NiSe are deposited from a precursor ink prepared by room-temperature dissolution of bulk elemental Ni and Se in a binary thiolamine solvent mixture. The nanostructured NiSe thin films demonstrate high HER catalytic activity with 100% Faradaic efficiency.
随着氢燃料成为比化石燃料更可行的替代品,人们对廉价、低能耗制氢的需求也随之而来。在此,我们提出了一种低温直接溶液处理方法,用于沉积储量丰富的黄铁矿型NiSe作为高效析氢反应(HER)催化剂。通过将块状单质Ni和Se在二元硫醇胺溶剂混合物中室温溶解制备前驱体墨水,从而沉积出相纯的NiSe薄膜。纳米结构的NiSe薄膜表现出高HER催化活性,法拉第效率达100%。
