A three-dimensional Ni foam deposited with graphene layers on surfaces is used as a conducting solid support to load MoS(x) catalysts for electrocatalytic hydrogen evolution. The graphene sheets grown on Ni foams provide robust protection and efficiently increase the stability in acid. The superior performance of hydrogen evolution is attributed to the relatively high catalyst loading weight as well as its relatively low resistance.
三维 Ni 泡沫表面沉积石墨烯层作为导电固体支撑,用于负载 MoS(x)催化剂进行电催化析氢。生长在 Ni 泡沫上的石墨烯片提供了强大的保护,有效地提高了在酸性环境中的稳定性。优异的析氢性能归因于较高的催化剂负载量和较低的电阻。
