A new 3-D open-framework cadmium borovanadate with 6-connected topology was hydrothermally obtained and structurally characterized. It not only features new cadmium(II) borovanadate which possesses an open-framework structure with unique plane-shaped channels, but also exhibits interesting absorption properties and high catalytic activities for the oxidation of cyclohexanol.
Insufficient separation of photogenerated electron−hole and feeble CO 2 activation remain the main obstacles in the access to high-performance CO 2 reduction nowadays. Single-atom active sites engineering could be an efficient method through simultaneously promoting charge separation and CO 2 activation. Herein, a model of Bi 4 O 5 I 2 with single-atom Fe implanting and accompanying Bi decorating on surface is proposed to boost the performance. The single-atom Fe implantation decreases the value of surface work function, allowing the fast transition of photon-generated electrons from the surface of catalyst to CO 2 molecule. In situ Fourier transform infrared (FT-IR) spectra, CO 2 adsorption measurements, density functional theory (DFT) calculations, and efficient CO 2 activation are realized on as-established singleatom catalyst. An exceptional yield of CO (23.77 μmol g −1 h −1 ) and CH 4 production (4.98 μmol g −1 h −1 ) is acquired over optimized Bi 4 O 5 I 2 −Fe30 with 1.09 wt % of singleatom Fe, superior to Bi 4 O 5 I 2 , and most other reported photocatalysts. The work paves a insight into rational design of photocatalysts toward simultaneously facilitating carrier separation and CO 2 activation from the angle of atom single metal.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
