The industrial ammonia synthesis process consumes a lot of energy and causes serious environmental pollution. As sustainable approach for synthesis, photocatalytic nitrogen reduction employing water as the reducing agent has potential. A simple surfactant-assisted solvothermal method is used to synthesize g-C3 N4 nanotubes with flower-like spherical BiOBr grown inside outside (BiOBr/g-C3 , BC). hollow tubular structure realizes full use visible light by multi-scattering effect light. Large surface areas more active sites N2 adsorption activation are present in distinctive spatially dispersed hierarchical structures. Particularly, quick separation transfer electrons holes facilitated sandwich heterojunctions tight contact interface . maximal NH3 generation rate BiOBr/g-C3 composite catalysts can reach 255.04 μmol⋅ g-1 ⋅ h-1 it 13.9 5.8 times that pure This work provides novel designing constructing unique efficient fixation.
