Photoelectrochemistry at bipolar semiconductor electrodes

Journal de Chimie Physique, 1996
Photoelectrochemistry may be performed on semiconductor wafers without application of metal contacts, using a cell in which the semiconductor sample is clamped between two suitable electrolytic solutions. Electrochemical control is obtained by applying a potential difference between two metal electrodes inserted in the solutions.

Dynamic Interfacial Charge Regulation for High-Fidelity Broadband Circularly Polarized Light Detection. [PDF]

Adv Sci (Weinh)
A photoelectrochemical circularly polarized light detector combines a multilayer chiral photonic film with a dynamically regulated BiVO4‐RGO‐MXene transducer. Broadband optical modulation from 360 to 830 nm is converted into stable electrical outputs through low‐noise solid‐liquid interfacial charge transfer, enabling self‐powered CPL discrimination ...

Photoelectrocatalytic Diazidation of Olefins via Synergistic Dual Iron Species. [PDF]

Adv Sci (Weinh)
We report a simple and general approach for 1,2‐diazidation of alkenes by a photoelectrochemical strategy using TMSN3 as an azide source. This transformation proceeds using earth‐abundant iron under mild reaction conditions. It displays broad functional group compatibility and accommodates diverse alkene types‐including unactivated, activated, electron‐

Nickel catalyzed multicomponent stereodivergent synthesis of olefins enabled by electrochemistry, photocatalysis and photo-electrochemistry

Nature Communications, 2022
The construction of trisubstituted alkenes with high stereoselectivity is challenging. Here, the authors realize the stereodivergent synthesis of such compounds via switching between electrochemistry, photochemistry and photoelectrochemistry.

Hydrogen From Simulated Seawater Using Long-Term Stable and Cost-Effective Plasmonic Photocatalysts. [PDF]

ChemSusChem
Can plasmonic photocatalysts withstand a saline environment? Yes! A conductive polyaniline shell stabilizes gold–silver nanoparticles while largely preserving charge transfer to TiO2, achieving 348 ± 108 μmol H2 g−1 h−1. Moreover, the catalyst survived 1 month of storage in simulated seawater, with almost full retention of its initial activity.
