Higher dye degradation using a visible-light photocatalyst made of mesoporous graphitic carbon nitride prepared with the Tween-40 surfactant

Synergistic redox reactions toward co‐production of H2O2 and value‐added chemicals: Dual‐functional photocatalysis to achieving sustainability

“…It is recognized that the bandgap of g-C 3 N 4 is ∼2.7 eV, with CB and VB positioned at approximately −0.8 and 1.9 eV (vs. normal hydrogen electrode at pH 0), respectively. 16,22,98,99 The characteristics endow g-C 3 N 4 to be visible-light responsive and the satisfactory band positions can provoke the 2e − WOR pathway, as well as a diversified range of photocatalytic reactions such as CO 2 reduction, [100][101][102] pollutant degradation, [103][104][105] and N 2 fixation. 36,106 However, as elucidated by the extensive researches, bulk g-C 3 N 4 itself suffers from detrimental issues such as inefficient charge separation, rapid charge recombination, low accessible surface area, and marginal visible-light harvesting, 39,41,107,108 which severely limit its practicability in performing 2e − WOR or photoredox reactions for H 2 O 2 production and selective chemical synthesis.…”

Synthesis and application of titanium dioxide photocatalysis for energy, decontamination and viral disinfection: a review

“…In recent years, much attention has been paid by the research community to the simultaneous removal of dyes as well as heavy metals (Louangsouphom et al 2019 ; de Lima et al 2020 ; Izzudin et al 2021 ). This methodology minimizes the processing time, operating cost as well as the use of chemicals in comparison with individual treatment methods.…”
