Porous graphitic carbon nitride for solar photocatalytic applications

Abstract

Photocatalysis is attracting increased attention in solving energy crisis and environmental pollution. Graphite carbon nitride (g-C3N4), a non-metal photocatalyst, has been regarded as an ideal photocatalyst to solve these problems because of its chemical stability and unique optical properties. However, the application of g-C3N4 is hindered by its low specific surface area and fast recombination rate of photogenerated electrons. Among the many strategies of modified g-C3N4, porous carbon nitride (PCN) can solve the shortcomings of g-C3N4 because of PCN’s increased surface-active site, specific surface area, light harvesting, duffision and adsorption/activation. However, a frontier, comprehensive summary about the PCN development is less reported. Thus, a review on recent developments in PCN research is urgently needed to further promote its advancement. In this review, the synthesis methods, structures, and properties and photocatalytic applications over the PCN photocatalysts are described in detail. The current challenges and future development of PCN/PCN-based photocatalysts are discussed. This review may present an up-to-date view of the PCN development to provide in-depth understanding of PCN-based photocatalysts.
