Efficient Photocatalytic Selective Oxidation of Benzylamines over Cobalt Molecular Catalyst Covalently Bonded to Carboxyl Functionalized Carbon Nitride

Advanced Energy & Sustainability Research, 2023
Photocatalysis is accepted as a promising method for selective oxidative coupling of amine to imine. However, owing to the rapid dehydrogenation of the generated imine intermediate of α‐amino hydrogen to butyronitrile, it remains a huge challenge to ...

Furfuryl Alcohol‐Driven Proton Supply Enables Efficient Photocatalytic H2O2 Production Beyond Water‐Based Systems

Advanced Science, EarlyView.
A ZnIn2S4–carbon dot heterojunction enables photocatalytic H2O2 production coupled with furfuryl alcohol oxidation. In this redox system, furfuryl alcohol acts as both the electron donor and oxidation substrate, producing furoic acid with 100% selectivity and 98% conversion while supporting efficient H2O2 generation with a solar‐to‐chemical conversion (

Programming Structural Symmetry and Emission in Low‐Dimensional Hybrid Perovskites via Time and Temperature

Advanced Science, EarlyView.
We demonstrate programmable structural symmetry and emission in benzylammonium‐based low‐dimensional hybrid perovskites. Continuous shaking transforms orthorhombic platelets into a lower‐symmetry monoclinic phase with broadband emission, whereas thermal activation drives the reverse pathways toward a higher‐symmetry configuration resembling the ...
