BET measurements were carried out to analyze the porosity of the carbon felts. In Figure 4, a comparison between

• the conduction band. Sulfur doping has also been shown to enhance the photocatalytic activity under visible-light illumination. Sulfur can be doped as an anion (S2−), replacing oxygen, or as a cation (S6+), thus replacing titanium [37][38]. Substitutional doping of sulfur in TiO2 narrows the band gap

• was fabricated by a one-pot impregnation co-precipitation method as shown in Figure 12a. The S doping was introduced to narrow the band gap of g-C3N4 by stacking its 2p orbitals on the valence band of bare g-C3N4 which eventually contributes to increase the efficiency. Furthermore, the sulfur doping

• -doped graphitic carbon nitride (CNS) nanosheets. During the synthesis, sulfur could be introduced as a dopant into the lattice of carbon nitride (CN). Sulfur doping changed the texture as well as relative band positions of CN. By growing CN on preformed sulfur-doped CN nanosheets, composite CN/CNS
