Artificial nitrogen fixation over bismuth-based photocatalysts: fundamentals and future perspectives

Abstract

Ammonia, one of the most basic substances in modern organic synthesis, is not only of great significance to human society, but also the back stone on which earth's life depends. Photocatalysis potentially provides a sustainable ammonia production technology as an alternative to the traditional Haber–Bosch process, which attracts extensive research interest recently. The development of efficient photocatalysts remains one of the fundamental issues for boosting the solar-to-ammonia efficiency. Significant and fruitful research on bismuth-based photocatalysts for nitrogen fixation to ammonia are reported in recent years. This review summarizes and discusses recent advances on photocatalytic nitrogen fixation to ammonia over bismuth-based semiconductors. The fundamentals of solar-to-ammonia conversion and reported methods for ammonia quantification are introduced, together with a specific focus on strategies to enhance the performances of bismuth-based photocatalysts for nitrogen fixation. Finally, we cast a personal prospect on the future development of this vibrant research area, by which we hope to provide a useful scaffold for future research for the rational design of efficient bismuth-based photocatalysts for sustainable ammonia production.
