Strong Interfacial Interaction in Polarized Ferroelectric Heterostructured Nanosheets for Highly Efficient and Selective Photocatalytic CO₂ Reduction

Abstract Heterojunctions are sustainable solutions for the photocatalytic CO 2 reduction reaction (CO RR) by regulating charge separation behavior at interface. However, their efficiency and product selectivity severely hindered inflexible weak built‐in electric field electronic structure of two phases. Herein, ferroelectric‐based heterojunctions between polarized bismuth ferrite (BFO(P)) CdS constructed to enhance interfacial interactions catalytic activity. The intrinsic polarization depending on ferroelectric state causes significant electrostatic potential difference energy‐band bending. This helps overcome unsatisfactory redox that differs from classical mechanism, synergy heterostructure facilitates effective transfer photogenerated charges with an extended lifetime (>20 ns) significantly enhanced photovoltage (1002 times BFO). optimized carrier dynamics allow heterojunction achieve a much higher yield compared state‐of‐the‐art photocatalysts, 85.46 23.47 than those pristine BFO, respectively. Moreover, it maintains impressive 100% together excellent repeatability cycling. work not only sheds light how strong inherent polarity promotes performance photocatalysts but also provides new insights designing efficient RR.

Cd Single Atom as an Electron Mediator in an S‐Scheme Heterojunction for Artificial Photosynthesis of H₂O₂

Abstract Developing conductor‐mediated S‐scheme heterojunction photocatalysts imitating natural photosynthetic systems emerges as a promising approach to hydrogen peroxide (H 2 O ) production. However, achieving precise coupling between two semiconductors with charge shuttle and modulating the interfacial interactions still remain significant bottleneck. Herein, we propose catalyst architecture Cd single atom mediated formed by interfacing CdS TiO nanoparticles. This exhibits an H production rate high 60.33 µmol g −1 min under UV–vis light irradiation, which is attributed efficient transport at interface of thanks S‐scheme. In‐situ X‐ray photoelectron spectroscopy (XPS) electron spin resonance (ESR) spin‐trapping tests confirm transfer route. Femtosecond transient absorption (fs‐TA) other ex‐situ characterizations further corroborate across interface. work offers new perspective on constructing atoms heterojunctions enhance photocatalytic performance.
