Plasma-engraved Co3O4 nanorods with enriched oxygen vacancies for efficient electrocatalytic ammonia synthesis† Ammonia electrosynthesis, emerging as a promising alternative to the conventional Haber–Bosch process, has garnered increased attention. In this study, a one-step plasma-engraving strategy is employed to modify the surface microenvironment of Co3O4 nanorods for the electrochemical nitrate reduction reaction (NO3RR), leading to a remarkable increase in oxygen vacancies.

Single atom catalysis for electrocatalytic ammonia synthesis Ammonia is a vital base molecule for modern agriculture and industry. As the commercially-mature approach for NH3 production, the traditional Haber–Bosch process has achieved great success; however, it also suffers from drawbacks such as massive energy consumption and huge CO2 emissions.
