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

Advanced Energy Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 13, 2025

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.

A Size-Adaptive Nanomicrobicide for Synergistic Photothermal and Gaseous Dismantling of Multidrug-Resistant Biofilms

Nano Letters, Journal Year: 2025, Volume and Issue: unknown

Published: March 6, 2025

Biofilms significantly impede the efficacy of conventional antimicrobial agents, particularly in multidrug-resistant (MDR) infections. In this work, we developed a size-adaptive, bismuth-based nanomicrobicide encapsulated with neutrophil membranes (Bi2S3/SNP@CM), designed to selectively generate nitric oxide (NO) within acidic biofilms under near-infrared (NIR) irradiation. The nanomicrobicide's adaptive size ensures deeper biofilm penetration and accumulation, while membrane coating enhances biocompatibility targeting at infection sites. Upon NIR irradiation, localized heating NO release synergistically eradicate MDR biofilms. Furthermore, interactions between glutathione, as well reactions ROS, disrupt intracellular redox balance, further amplifying antibacterial efficacy. This innovative design affords promising for effectively treating

Abstract As a typical representative of Metastable intermolecular composites (MICs), the energy release nano‐thermites relying on aluminum‐oxygen reaction is limited by formation high boiling point condensed phase products. Low pressure output performance constitutes another pivotal factor influencing their efficacy. In this work, metal fluorides BiF 3 at different scales were incorporated into as oxidants, thereby facilitating tunability released energy. The points all resultant products fall below combustion temperature, theoretically abolishing agglomeration condensed‐phase products, thus preventing entrapment active metals. Additionally, it facilitates smooth conduction heat flux, averting losses in biphasic flow dynamics. n‐Al/n‐BiF system exhibits significant amplification reactive kinetic properties stark contrast to n‐Al/n‐Bi 2 O system. reduction ignition threshold ascribed novel kinetics mechanism within n‐Al/BiF highly electronegative fluorine corrodes Al shell, inducing “pre‐ignition” reaction. application Density Functional Theory (DFT) evaluations has further corroborated system's preeminence electron transfer capacity between oxidizing agent and fuel, furnishing an molecular‐electronic basis for its potent properties.
