Recent advances of polymer carbon nitrides toward photosynthesis of hydrogen peroxide

双氧水(H2O2)是一种重要的无机化工产品,在生物、化学、制药和环境等领域应用广泛.工业上生产H2O2的方法主要为蒽醌法,这种方法不仅消耗的能量大,还会带来严重的环境污染.光合成H2O2主要利用太阳能、水和氧气来制造H2O2,既能减少污染,又能降低成本,因此引起了科学界的广泛研究.本文围绕聚合物氮化碳基材料用于光合成H2O2的研究,总结近年来聚合物氮化碳材料的合成、改性及其在光合成H2O2领域应用的研究进展,同时也探讨了聚合物氮化碳基催化剂在光合成H2O2领域面临的挑战和发展前景.

Hydrogen peroxide(H2O2)is a kind of basic inorganic chemical product,which has been extensively developed in biology,chemistry,pharmacy,and environmental protection.H2O2 is mainly produced by the energy-wasting and environmentally-harmful anthraquinone process in industry.Photocatalyic synthesis of H2O2 by utilizing solar energy,water and O2 can reduce the production cost and the environment pollution,therefore has brought a hot-spot of research.In this review,we summarize the recent research advances in synthesizing and modificating polymer carbon nitride-based photocatalysts,and their applications in the photosynthesis of H2O2.The current challenges and opportunities of the polymer carbon nitride-based photocatalysts for the photosynthesis of H2O2 are also discussed.
