Introduction of electron-deficient unit in resorcinol-formaldehyde resin to construct donor–acceptor conjugated polymer for enhancing photocatalytic H₂O₂ production

Abstract

Photocatalytic two electron oxygen reduction reaction is considered a promising approach for green H2O2 production. Herein, for the first time, intramolecular donor-acceptor (D-A) conjugated polymer was constructed in resorcinol-formaldehyde (RF)...

Recent advancements in graphitic carbon nitride based direct Z- and S-scheme heterostructures for photocatalytic H2O2 production

“…A number of semiconductors, namely metal oxides, 30 metal sulfides, 35–37 metal phosphides, 38,39 transition metal dichalcogenides, 40 transition metal oxyhydroxides, 41 metal–organic frameworks (MOFs), 42–44 carbon-based semiconductors, 45–47 metal-free organic semiconductors like g-C 3 N 4 , 48–50 resins, 51–58 covalent triazine frameworks (CTFs), 59 covalent organic frameworks (COFs), 60,61 covalent heptazine frameworks (CHFs) 62 and Bi-containing semiconductors, 63–65 have been extensively investigated for photocatalytic H 2 O 2 production. Despite significant research, the field still faces challenges such as low photoconversion efficiency and rapid e − /h + pair recombination, which limit its practical applications.…”
