MOF-derived synthesis of MnS/In2S3 p-n heterojunctions with hierarchical structures for efficient photocatalytic CO2 reduction

MOFs‐Derived Fusiform In2O3 Mesoporous Nanorods Anchored with Ultrafine CdZnS Nanoparticles for Boosting Visible‐Light Photocatalytic Hydrogen Evolution

“…[ 31,33–36 ] Lately, In 2 O 3 photocatalysts derived from the pyrolysis of In‐contained metal–organic frameworks (MOFs) have received increasing attention. [ 37–42 ] It is widely believed that the MOFs‐derived In 2 O 3 can completely retain the high specific surface area and porous framework of MOFs, which can provide a great deal of reaction sites for photocatalytic reactions, thereby promoting the photocatalytic activity. Moreover, the inherited or created pores of MOFs‐derived In 2 O 3 can also act as guests or hosts for in situ incorporating other foreign semiconductor nanostructures to further improving the photocatalytic activity by forming a heterojunction.…”

Challenges and prospects in the selective photoreduction of CO2 to C1 and C2 products with nanostructured materials: a review

“…The type-II heterostructures were also explored because the separation and migration of e − /h + pairs were more appropriate at the electrode–electrolyte interface. The p–n heterojunction-based systems such as Bi 2 S 3 /CdS, 9 CeO 2 /3Dg-C 3 N 4 , 89 MXene/Bi 2 WO 6 , 95 ZnO/Co 3 O 4 , 139 CuO/ZnO, 92 NiO/g-C 3 N 4 , 91 BiFeO 3 /ZnO, 90 Bi 2 WO 6 /BiOI, 88 g-C 3 N 4 /Bi 9 O 7.5 S 6 140 and TiO 2 /ZnO 141 were reported for the photoreduction of CO 2 to valuable products (Table 2). Huang et al reported the Co 3 O 4 @CdIn 2 S 4 p–n junction catalyst for the reduction of CO 2 under visible light.…”

Rational Design of Metal–Organic Framework‐Based Materials for Photocatalytic CO2 Reduction

“…Li's group converted Mn‐adsorbed MIL‐68 to a p–n heterostructure, that is, MnS/In 2 S 3 via a sulfidation process with thiourea. [ 109 ] The obtained MnS/In 2 S 3 nanosheets were assembled to form a nanotube morphology, which could provide a high surface area and increased active sites. The p–n heterojunction composed of MnS and In 2 S 3 could effectively enhance the charge separation in the photocatalytic process.…”
