Natural Anthraquinone‐Like Compound Extracted from Green Husk of Walnut Improves Photocatalytic H2O2 Production Catalyzed by TiO2 Nanoparticles

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
In this work, a novel biomolecule/semiconductor hybrid catalyst was prepared by loading anthraquinone‐liked juglone onto anatase TiO2. This catalyst exhibited high photocatalytic activity for H2O2 production. Hydrogen peroxide (H2O2) is a vital oxidant with broad industrial applications, and its production via photocatalysis represents a highly ...

Precisely Constructed Asymmetric Coordination Tuned High‐Spin Co Sites for Sacrificial Agent‐Free H2O2 Photocatalytic Production

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The asymmetric Co–N2O2 coordination structure was precisely constructed through the assembly of Salen COF. The high‐spin (t2g4eg3$$ {\mathrm{t}}_{2\mathrm{g}}^4{\mathrm{e}}_{\mathrm{g}}^3 $$) Co center enables Pauling‐type O2 adsorption, inhibiting the cleavage of the O–O bond. π‐d conjugation enhances charge separation and transport.

Design, Synthesis, and Photophysical Studies of Functionalized Polyaromatic Isonitriles as Visible Light Photoredox Catalysts

European Journal of Organic Chemistry, EarlyView.
A new series of structurally rich polyaromatic isonitriles is presented as photoredox catalysts. Their photophysical properties are investigated by UV–Vis absorption and fluorescence measurements, combined with experimental and theoretical studies to evaluate both ground‐ and excited‐state redox properties.
