Facile construction of a hierarchical Bi@BiOBr–Bi2MoO6 ternary heterojunction with abundant oxygen vacancies for excellent photocatalytic nitrogen fixation

A facile two-step solvothermal strategy was applied to prepare Bi@BiOBr–Bi₂MoO₆ ternary heterojunction with plentiful oxygen vacancies that can be used to effectively fix nitrogen without any organic scavengers or noble-metal cocatalysts.
