Heterojunction photocatalysts for artificial nitrogen fixation: fundamentals, latest advances and future perspectives.
TLDR
In this article, a wide spectrum of recently developed heter-structured photocatalysts for nitrogen fixation to ammonia are evaluated and the fundamentals of solar-to-ammonia conversion, basic principles of various heterojunction photocatalyst and modification strategies are systematically reviewed.Abstract:
As an indispensable energy source, ammonia plays an essential role in agriculture and various industries. Given that the current ammonia production is still dominated by the energy-intensive and high carbon footprint Haber-Bosch process, photocatalytic nitrogen fixation represents a low-energy consuming and sustainable approach to generate ammonia. Heterostructured photocatalysts are hybrid materials composed of semiconductor materials containing interfaces that make full use of the unique superiorities of the constituents and synergistic effects between them. These promising photocatalysts have superior performances and substantial potential in photocatalytic reduction of nitrogen. In this review, a wide spectrum of recently developed heterostructured photocatalysts for nitrogen fixation to ammonia are evaluated. The fundamentals of solar-to-ammonia conversion, basic principles of various heterojunction photocatalysts and modification strategies are systematically reviewed. Finally, a brief summary and perspectives on the ongoing challenges and directions for future development of nitrogen photofixation catalysts are also provided.read more
