Effect of Ni/Rh ratios on characteristics of NixRhy nanosponges towards high-performance hydrogen evolution reaction

Abstract The data presented in this article are related to the research article entitled “NiRh Nanosponges with Highly Efficient Electrocatalytic Performance for Hydrogen Evolution Reaction (N.-A. Nguyen et al., 2019) [1]. This article reports a facile method to prepare various Ni x Rh y nanosponges while using NaBH 4 as a reducing agent without using any surfactant. The structural and chemical properties of the obtained Ni x Rh y nanosponges are investigated.
