Cover Feature: Two‐Dimensional Boridene Nanosheets for Efficient Electrochemical Nitrogen Fixation Under Ambient Conditions (ChemSusChem 6/2025)

The Cover Feature shows electrocatalytic ammonia synthesis, an alternative technology to the high-pressure and -temperature Haber–Bosch process, that can be conducted under ambient conditions by using renewable energy sources. However, limited activity and selectivity hinder its practical applications. In their Research Article (DOI: 10.1002/cssc.202401912), L.-X. Ding, G.-F. Chen, H. Wang and co-workers propose boridene enriched with metal vacancies as a novel catalyst for efficient electrocatalytic nitrogen reduction reaction under ambient conditions, aiming to facilitate green ammonia synthesis.
