Alkyl group-decorated g-C₃N₄ for enhanced gas-phase CO₂ photoreduction

Abstract

With excellent physical/chemical stability and feasible synthesis, g-C3N4 has attracted wide attention in the filed of photocatalysis. However, the weak photoactivity limits its practical applications. Herein, by easily planting hydrophobic...

Single-site bipyridine cobalt complexes covalently embedded into graphitic carbon nitride with excellent photocatalytic activity and selectivity towards CO2 reduction

“…Copolymerization with organic molecules bearing suitable functional groups such as amino, cyano, or aldehyde is a widely adopted approach to tuning the properties of g-CN. [42][43][44][45][46][47] A series of organic molecules have been covalently embedded into the skeleton of g-CN through facile one-pot thermal copolymerization and the visible-light absorption range, the specific surface area, and the conductivity of g-CN were apparently elevated to different degrees. To incorporate the dualfunctional organic molecules, for example, 2,2′-bpy, which can not only regulate the properties of g-CN, the N atoms in 2,2′bpy can concurrently coordinate with metal atoms as singlesite catalytic centers is still less studied up to now.…”

Ordered and carbon-doped porous polymeric graphitic carbon nitride nanosheets toward enhanced visible light absorption and efficient photocatalytic H2 evolution

“…Among organic semiconductors, graphitic carbon nitride (g-C 3 N 4 , GCN) has become an attractive photocatalytic material due to its earth-abundant nature, tunable electronic structure, good physicochemical stability, and narrow bandgap of ∼2.7 eV. [13][14][15] The framework of g-C 3 N 4 is formed by the unique tri-s-triazine, which will conduce to the binding or intercalation of foreign atoms with C/N or functional groups on GCN. 16 Moreover, the rich content of pyridine nitrogen in the triazine/heptazine rings of the GCN framework could offer rich electron lone pairs to capture metal ions, which is favorable to the identification of catalytically active sites.…”

Multi-heteroatom-doping promotes molecular oxygen activation on polymeric carbon nitride for simultaneous generation of H2O2 and degradation of oxcarbazepine

“…In addition, by facilitating charge separation, more available electrons can be captured and participate in surface reactions. [37][38][39] Thus, the degradation of OXC with simultaneous H 2 O 2 generation is of particular interest for the development of wastewater treatment since H 2 O 2 is an environmentally friendly oxidizing agent that under certain conditions can generate the highly reactive • OH.…”
