Photocatalytic ammonia synthesis is a promising strategy for sustainable development compared to the energy-intensive industrial Haber-Bosch approach. Herein, a ternary heterostructure that consists of ruthenium species and carbon nitride (C3N4) was rationally explored for ammonia photosynthesis. Compared to the small ammonia yield from the g-C3N4 and Ru/g-C3N4 system, the Ru/RuO2/g-C3N4 system represents 6 times higher activity with excellent stability under full-spectrum irradiation. Such an enhancement is not only due to efficient transfer of electrons and holes to Ru and RuO2, respectively, facilitating both the reduction and oxidation reaction, but also taking advantage of Ru for N[triple bond, length as m-dash]N activation.

Ru and RuOx decorated carbon nitride for efficient ammonia photosynthesis

Studies of photocatalytic conversion of CO2 into hydrocarbon fuels, as a promising solution to alleviate global warming and energy issues, are booming in recent years. Researchers have focused their interest in developing g-C3N4 composite photocatalysts with intriguing features of robust light harvesting ability, excellent catalysis, and stable performance. Four types of heterojunctions (type-II, Z-scheme, S-scheme and Schottky) of the g-C3N4 composites are widely adopted. This review aims at presenting and comparing the photocatalytic mechanisms, characteristics, and performances of g-C3N4 composites concerning these four types of heterojunctions. Besides, perspectives and undergoing efforts for further development of g-C3N4 composite photocatalysts are discussed. This review would be helpful for researchers to gain a comprehensive understanding of the progress and future development trends of g-C3N4 composite heterojunctions for photocatalytic CO2 reduction.
