Amorphous Chromium Oxide with Hollow Morphology for Nitrogen Electrochemical Reduction under Ambient Conditions

The electrocatalytic nitrogen reduction reaction (NRR), an alternative method of nitrogen fixation and conversion under ambient conditions, represents a promising strategy for tackling the energy-intensive issue. The design of high-performance electrocatalysts is one of the key issues to realizing the application of NRR, but most of the current catalysts rely on the use of crystalline materials, and shortcomings such as a limited number of catalytic active sites and sluggish reaction kinetics arise. Herein, an amorphous metal oxide catalyst H-CrO
