Development of Sulfur-Doped Graphitic Carbon Nitride for Hydrogen Evolution under Visible-Light Irradiation

“…0.326 nm) of motifs existing in the conjugated aromatic systems, revealing the formation of the pronounced graphitic structure of g-C 3 N 4 [ 33 , 46 ]. Noticeably, the XRD peaks of both PCN and S-doped CN samples are highly similar, implying a well preserving of the general structure of g-C 3 N 4 even after S doping [ 58 ]. Nevertheless, two distinguished changes have been found after S doping, i.e., the weakening in the intensity and the shifting of 2θ angle to a higher angle value, for the both diffraction peaks.…”

Effects of K-doping on the microstructure and photocatalytic performance of porous g-C3N4 nanosheets

“…12 However, the large interlayer distance of a graphite-like layered structure limits the transport of photogenerated electrons, and serious recombination of photogenerated carriers affects its external quantum efficiency. 13 To improve the photocatalytic performance, modifications of g-C 3 N 4 are commonly used, 14 including morphology control, 15,16 element doping, 17,18 previous metal deposition, 19,20 and semiconductor compounding. 21,22 Morphology control and element doping are simple and effective methods.…”

Boosted photocatalytic performance on molecule/semiconductor hybrid materials: conversion of sunlight energy into hydrogen fuel

“…To solve these issues, construction of an efficient photocatalytic system is of the utmost significance. Under these circumstances, ever more endeavors have contributed to the development of semiconductor materials through doping, 4,5 sensitization, 6,7 construction of heterojunctions, 8,9 Z-scheme systems, 10,11 establishment of microsize architectures, 12,13 annexing appropriate molecular catalyst [14][15][16] and other thermodynamic and kinetics methods. Among them, loading a suitable molecular catalyst is widely perceived to be a promising method to enhance catalytic application of a single semiconductor that can synchronously implement dissociation of the exciplex, accelerate surface reaction kinetics, and suppress counterreactions.…”
