Cu-doped hollow tubular ZnInS using MIL-68-NH as templates for efficient photocatalytic synthesis of HO in ambient air and pure water.

Utilizing metal-organic frameworks as templates to synthesize photocatalysts has garnered increasing attention thanks to their substantial advantages. In this study, Cu-doped ZnInS with hollow tubular structures was ingeniously synthesized using MIL-68-NH as a template for photocatalytic HO production in ambient air and pure water under visible light. The hollow tubular structures promote light penetration and reflection, furnish substantial accessible reactive sites and accelerate the diffusion of reactants and products.

Carboxylated cellulose-derived carbon mediated flower-like bismuth oxyhalides for efficient Cr(VI) reduction under visible light.

Exquisitely tailoring the morphologies of photocatalysts could achieve high activities. In this study, the morphological transformation of bismuth oxyhalide (BiOX, X = Br, I and Cl) from disordered lamellae to regular flowers was facilely achieved via the use of carboxylated cellulose-derived carbon (CDC). The sphere-like structure and abundant surface functional groups of CDC induce the formation of such flower-like morphologies of BiOX/CDC, and this morphology results in a pronounced increase in surface area (e.

Metal-Organic Framework Templated Z-Scheme ZnInS/BiS Hierarchical Heterojunction for Photocatalytic HO Production from Wastewater.

Metal-organic framework derived materials received a lot of attention due to their significant benefits in photocatalytic reactions. In this work, a Z-scheme ZnInS/BiS hierarchical heterojunction is first developed by a one-pot method using CAU-17 as a template. The specific preparation method endows an intimate interface contact between these two monomers, and CAU-17-derived BiS possesses a high surface area and porosity, resulting in an efficient charge separation and O capture.

Interspersing CdS nanodots into iodine vacancy-rich BiOI sphere for photocatalytic lignin valorization.

Flower-like BiOI was decorated by CdS nanodots and followed by the introduction of iodine vacancies (V) for photocatalytic sodium lignosulfonate (SLS) valorization under visible light. The iodine vacancies could adjust the band configuration, strengthen the light absorption and act as electron traps, while the intimate contact between BiOI and CdS nanodots provides a high-speed channel for charge transfer. As a consequence, the photocatalytic performance of SLS conversion into value-added vanillin was greatly improved over CdS/BiOI-V compared with those of CdS, BiOI and CdS/BiOI.

Cellulose-Derived Carbon Dot-Guided Growth of ZnIn S Nanosheets for Photocatalytic Oxidation of 5-Hydroxymethylfurfural into 2,5-Diformylfuran.

Cellulose-derived carbon (CC) dot-directed growth of ZnIn S was achieved through hydrothermal treatment of carboxylated cellulose followed by in situ growth of ZnIn S nanosheets. The carbon dots inherited from carboxylated cellulose equip plenty of surface carboxyl groups, which induce the ionic interaction with Zn and In and the guided growth of ZnIn S . As a result, the nanosheets of ZnIn S are evenly and intimately grown on the small carbon dots, providing high-speed channels for charges transfer.
