Abstract
Photocatalytic dinitrogen (N2) fixation is regarded as an achievable technology for ammonia (NH3) production. However, the poor separation efficiency of the photoinduced carriers and ineffective N2 activation remain grand obstacles to high-performance NH3 photosynthesis. Designing advanced heterostructured systems to accelerate charge separation and activate the N2 molecule is a feasible strategy to optimize the photocatalytic N2 fixation activity. Herein, a direct Z-scheme configuration is established between BiOBr and Bi4O5Br2 through a facile one-step solvothermal reaction. This configuration enables effective spatial separation of electron–hole pairs and preserves the robust redox ability of carriers,…
