Highly efficient photocatalytic degradation over rose-like 1D/2D La(OH)₃/(BiO)₂OHCl heterostructures boosted by rich oxygen vacancies and enhanced interfacial charge transfer

Abstract

In this paper, novel rose-like photocatalysts constructed by 1D/2D La(OH)3 nanorod/(BiO)2OHCl nanosheet heterojunctions were successfully fabricated. The optimal sample (BOL-2, synthesized with Bi/La molar ratio of 4:1) showed significantly boosted...

One-pot molten-salt construction of channels for hole transport and mass transfer over CoS2 nanocubes for visible-light-driven CO2 reduction

“…4e), indicating that loading CuSCN can inhibit the charge recombination of photogenerated electrons and holes over the heterojunction, and more photogenerated electrons will participate in the reduction of CO 2 . 47 The results of the time-resolved fluorescence also confirm this result. As shown in Fig.…”

Crystal facet and Na-doping dual engineering ultrathin BiOCl nanosheets with efficient oxygen activation for enhanced photocatalytic performance

“…Up to now, surface defect particularly oxygen vacancies (OVs) engineering has been widely explored to improve the visible-light-driven O 2 activation and the ROS generation in BiOCl and other Aurivillius phase materials such as (BiO) 2 OHCl and Bi 2 MoO 6 . 18,19 Various strategies have emerged for the construction of surface defects, such as nonmetal or metal doping, solvothermal reduction and liquid-exfoliation, of which, the nonmetal or metal doping has been proved as one of the most facile and effective strategies. For example, Deng et al prepared BiOCl x Br 1−x and BiOCl x I 1−x solid solutions by in situ doping of nonmetal ions (Br − and I − ) during the synthesis of BiOCl.…”
