Z-scheme heterojunction g-C3N4@PDA/BiOBr with biomimetic polydopamine as electron transfer mediators for enhanced visible-light driven degradation of sulfamethoxazole

Construction of a Z-scheme g-C3N4/NBGO/BiVO4 heterostructure with visible-light driven photocatalytic degradation of tetracycline: efficiency, reaction pathway and mechanism

“…The h + , ˙O 2 − and ˙OH are generally the primary active oxidants involved in the photocatalytic process. 65–68 The results are shown in Fig. 11a and b.…”

MOFs Derived Hetero-ZnO/Fe2O3 Nanoflowers with Enhanced Photocatalytic Performance towards Efficient Degradation of Organic Dyes

“…Thus, all electrons and holes would only stay within the sole Fe2O3 component of the composite, and their recombination probability is greatly increased. In particular, the electrons accumulated on the CB of Fe2O3 cannot reduce the O2 molecules adsorbed on the catalyst surface to produce •O2because of its more positive ECB potential than E(O2/•O2 -) (−0.046 eV vs. NHE) [55], and only the slightly left holes on the VB of Fe2O3 can generate reactive species of •OH due to its more positive EVB than E(H2O/•OH, 2.27 eV vs. NHE) and E(OH -/•OH, 1.99 eV vs. NHE) [56]. Based on the above analysis, the introduction of Fe2O3 into ZnO may result in the decrease in concentration of reactive species, and photocatalytic activities are weakened.…”

Enhancing the peroxidase-like activity of MIL-88B by ligand exchange with polydopamine

“…24,25 In addition, it is convincing that the exchange of ligands between PDA and the surface of MOFs is more conducive to electron migration during the Fenton-like reaction, based on the facts that PDA is an organic semiconductor and has good electronic transmission capabilities. 21,26 In summary, it will be a very promising method to enhance the enzyme-like activity of MOF nanozymes through PDA.…”
