Bismuth oxyhalides (BiOX, X = Cl, Br, and I) have emerged as viable catalysts for photocatalytic reduction of nitrogen into ammonia, due to their unique electronic structures and optical properties. Herein, the recent progress of BiOX-based photocatalysts for nitrogen fixation, with a focus on the reaction mechanism and pathways, materials preparation, and strategies of structural engineering for enhanced performance, is summarized. The article is concluded with a perspective where the promises and challenges of bismuth-based photocatalysts for nitrogen reduction to ammonia are highlighted, along with possible future research directions. %B Advanced Energy and Sustainability Research %V 2 %P 2000097 %G eng %U http://onlinelibrary.wiley.com/doi/abs/10.1002/aesr.202000097 %R http://doi.org/10.1002/aesr.202000097
