Graphdiyne as a Hole‐Transport Channel in Carbon Nitride Heterojunctions for Synergistic CO2 Reduction and γ‐Butyrolactone Synthesis

Angewandte Chemie, EarlyView.
A fully metal‐free heterojunction constructed from graphdiyne (GDY) and polymeric carbon nitride (PCN) enables efficient coupling of CO2 reduction and tetrahydrofuran oxidation. GDY serves as a hole‐transport channel, establishing a built‐in electric field that drives spatial charge separation. The optimized catalyst achieves near‐unity selectivity for

W‐N‐C Tandem Catalytic Centers Mediating Efficient Charge Transfer for the Enhanced Radical‐Path U(VI) Photoreduction

Advanced Science, EarlyView.
This work constructed a tandem W−N−C center to simultaneously achieve the regulation of reaction pathways and optimization of charge separation efficiency. The Lewis‐acidic W6+ sites activated O2 to generate O2−$O_2^ - $, with enhanced charge separation via electronic modulation, steering U(VI) reduction down an efficient radical pathway.

Synergistic Lewis Acid Photocatalysis Over Cluster‐Defect‐Engineered UiO‐66 for Efficient Liquid Biomass Upgrading

Angewandte Chemie, EarlyView.
A cluster‐defect engineering strategy is presented for the rational design of Zn‐incorporated UiO‐66 photocatalysts. Selective acid etching mediates hierarchical porosity and abundant Lewis acid sites, tailoring the electronic structure and enhancing light harvesting.

Photoelectrochemical Analysis of Ascorbic Acid

Analytical Chemistry, 1998
Channel electrode voltammetry is used to analyze for ascorbic acid via its photochemical reaction with toluidine blue. On formation by light of wavelength ∼630 nm, the excited state of the dye undergoes an irreversible redox reaction with ascorbic acid producing the reduced form of the dye and oxidized ascorbic acid.

Porous Organic Cages for CO2 Capture and Confined Reduction

Angewandte Chemie, EarlyView.
Porous organic cages (POCs) enable the coupling of CO2 capture and conversion through the interplay of molecular structure and solid‐state organization. Beyond intrinsic cavities, packing‐dependent pore accessibility and mass transport govern local CO2 concentration and catalytic performance, linking adsorption to reactivity in integrated capture ...

Surface Fermi Level Modulation of Photoanode by Optimized Conducting Nanoparticle Heterointerfaces for Enhanced Photoelectrochemical Water Splitting

Advanced Science, EarlyView.
Optimizing the heterointerface coverage of the conducting Ni2P nanoparticles on the surface of BVO photoanode manipulates the surface Fermi‐level modulation, which significantly enhances photoelectrochemical oxygen evolution reaction. Our multiscale simulations and experimental results reveal that an optimal Ni2P coverage of 9.4% pins the surface Fermi

Photoelectrochemical cell with cadmium telluride film

, 1978
ELLIS et al.1 reported studies of single crystal CdX based photoelectrochemical cells when X = S, Se or Te and found that the best efficiencies were obtained when CdTe was used as the photoelectrode. Photoelectrochemical cells using thin films of CdS and
