Enhancing Green Ammonia Electrosynthesis Through Tuning Sn Vacancies in Sn-Based MXene/MAX Hybrids.

Renewable energy driven N electroreduction with air as nitrogen source holds great promise for realizing scalable green ammonia production. However, relevant out-lab research is still in its infancy. Herein, a novel Sn-based MXene/MAX hybrid with abundant Sn vacancies, Sn@TiCT/TiSnC-V, was synthesized by controlled etching Sn@TiSnC MAX phase and demonstrated as an efficient electrocatalyst for electrocatalytic N reduction.
