Ferroelectric‐enhanced Photoelectrochemical Water Splitting: A Review of Recent Progress on the Mechanism

Small, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 27, 2025

Photoelectrochemical (PEC) water splitting is a top green tech for renewable energy, turning solar power into storable hydrogen. The efficiency of PEC constrained by charge separation and surface reactions. While traditional material modifications like heterojunction design defect regulation have enhanced efficiency, they are limited properties. ferroelectric provides novel strategy to address these limitations in splitting. Ferroelectric materials, with their spontaneous polarization, can enhance regulate reactions via internal electric fields. This paper summarizes the mechanism polarization its role PEC, especially how promotes bulk It also reviews research progress made recent years regarding enhancement performance through polarization. includes applications two main aspects: separation, which involves pure ferroelectrics, ferroelectric-semiconductor heterojunctions, ferroelectric-plasmonic structures; reactions, cover electronic structure modification, pH regulation, nanostructures. Studies shown that significantly improve optimize reaction kinetics regulating interfacial energy band structure. Finally, future development this promising field prospected.

Photoelectrocatalytic Cl-mediated C(sp3)–H aminomethylation of hydrocarbons by BiVO4 photoanodes

Nature Communications, Journal Year: 2025, Volume and Issue: 16(1)

Published: March 8, 2025

Interfacial photoelectrochemistry at photoanodes has been extensively researched for solar energy conversion, but its application the production of high-value-added chemical compounds in organic chemistry still presents challenges. Herein, we report photoelectrocatalytic Cl-mediated C(sp3)–H aminomethylation alkanes with self-developed and reusable BiVO4 photoanodes. The swift condensation aniline aldehydes, along decrease electricity input by photogenerated holes photoanodes, work together to prevent excessive oxidation aniline, leading high yields desired product. Mechanistic experiments demonstrate that Cl- ions, as key mediators, could be attracted oxidized form Cl2. This is followed light-promoted homolytic cleavage Cl2, generating Cl radicals efficiently abstract hydrogen atoms from hydrocarbons. opens an avenue interfacial photoelectrochemical synthesis demonstrates a potential method optimizing conversion into fuels. A stable recyclable photoelectrode material was developed efficient hydrocarbons cell, which provides promising fuel conversion.
