Abstract

Apart from water and carbon dioxide as described in previous chapters, nitrogen can be also processed by solar energy for producing solar fuels. Ammonia (NH3), one of the most critical chemicals, is extensively applied in the fertilizer production and regarded as an emerging energy carrier. Artificial photocatalytic and photoelectrochemical N2 fixation using the renewable energy under ambient conditions has opened a new horizon for the sustainable NH3 synthesis, owing to its cost-efficient and environmentally friendly processes. The performance of the photocatalytic and photoelectrochemical N2 reduction is highly related to the development of promising catalysts. Moreover, a deeper understanding of N2 fixation is extremely essential for the rational design of desirable catalysts. In this chapter, we introduce the recent advances in photocatalytic and photoelectrochemical N2 reduction to NH3. Firstly, the fundamental principles on N2 reduction are presented. Then, the current design strategies, mainly including the defect engineering, structural regulation, interface control, heterojunction construction, co-catalyst engineering, and biomimetic engineering, for the preparation of heterogeneous catalysts are summarized. Finally, the remaining challenges as well as future perspectives in this very exciting research field are outlined. It is anticipated that the content in this chapter will not only shed new lights on the rational design of catalysts but also provide useful guidance for future explorations in this emerging field.
