Chalcogen Elements in Regulating the Local Electron Density of Cu2X for an Efficient Heterogeneous Fenton-like Process

“…Considering the low utilization efficiency of H 2 O 2 , a number of studies have proposed various strategies to enhance the Fenton reactivity, including introducing external electric fields and injecting electrons from electron-rich materials, semiconductors, or doping metals in Fenton catalysts to promote the decomposition of H 2 O 2 . − For instance, it was reported that H 2 O 2 utilization efficiency was 33-fold higher with carbon quantum dots (CQDs)-mediated Fe­(II/III) redox owing to the unpaired electron defects and carboxylic groups at the edge of CQDs that improved the sluggish Fe­(II) generation . In addition, Pan et al found that the presence of electron-rich regions around Cu atoms played important roles in the generation of • OH and electron transfer between Fe and Cu when Cu was substituted in LaFeO 3 .…”
