Nickel cobalt oxide hollow nanosponges as advanced electrocatalysts for the oxygen evolution reaction

Autor: Matthias Holzschuh, Dan Wen, Frank Simon, Stefan Kaskel, Wei Liu, Susanne Leubner, Chengzhou Zhu, Martin Oschatz, Alexander Eychmüller

A class of novel nickel cobalt oxide hollow nanosponges were synthesized through a sodium borohydride reduction strategy. Due to their porous and hollow nanostructures, and synergetic effects between their components, the optimized nickel cobalt oxid
