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

ABSTRACT: Renewable energy driven N₂ 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@Ti₂CT_X/Ti₂SnC-V, was synthesized by controlled etching Sn@Ti₂SnC MAX phase and demonstrated as an efficient electrocatalyst for electrocatalytic N₂ reduction. Due to the synergistic effect of MXene/MAX heterostructure, the existence of Sn vacancies and the highly dispersed Sn active sites, the obtained Sn@Ti₂CT_X/Ti₂SnC-V exhibits an optimal NH₃ yield of 28.4 µg h^-1 mg_cat^-1 with an
