S-Scheme Heterojunction Based on Resorcinol–Formaldehyde Resin Nanosheets and Bi-Based Metal–Organic Frameworks for Efficient Photocatalytic H2O2 Production

“…In recent years, metal–organic frameworks (MOFs) have attracted great interest due to their unique pore structure, abundant reactive sites, and excellent catalytic activity. − Due to the nontoxic and harmless properties of Bi-metal, its relatively low price, and various coordination environments, people’s attention has gradually shifted to bismuth-based MOFs. , As a result, various effective heterojunctions based on inorganic semiconductors and Bi-MOFs have been developed, such as Cs 3 Bi 2 Br 9 /Bi-MOF, Bi/BiO 2 -X–Bi 2 O 2 CO 3 /BiOCl@Bi–MOF, Bi 2 WO 6 /Bi-MOF, and Bi-MOF@BiOX (X = I, Br and Cl), which were developed to improve their photocatalytic performance significantly. However, the wide band gap of Bi-MOF makes it only accept ultraviolet light, which hinders its practical application.…”
