We prepared antimony metal films via electrodeposition, followed by the synthesis of Sb2S3 through a chemical vapor phase reaction. Finally, an Sb2O3 film was deposited onto using bath method, successfully constructing heterojunction photocathode Sb2S3/Sb2O3; synthesized Sb2S3/Sb2O3 is classified as Type I heterostructure. The resulting exhibited photocurrent density −0.056 mA cm−2 at −0.15 V (vs. RHE), which 1.40 times higher than that alone under simulated solar illumination. Additionally, demonstrated lower carrier recombination rate and faster charge transfer compared to Sb2S3, evidenced photoluminescence electrochemical impedance spectroscopy tests. For these reasons, obtained hydrogen precipitation 0.163mL h−1, twice condition 60 min light exposure. significant enhancement in photoelectrochemical performance attributed formation heterojunction, improves both separation efficiency. This strategy holds promising potential for visible light-driven water splitting.

Unveiling Mechanically Driven Catalytic Processes: Beyond Piezocatalysis to Synergetic Effects

ACS Nano, Год журнала: 2025, Номер unknown

Опубликована: Май 6, 2025

Mechanically driven catalysis (MDC) has emerged as an effective strategy for environmental remediation, renewable energy conversion, and cancer therapy; this functions by converting mechanical forces to drive catalytic reactions. This review examines four primary mechanisms, namely, piezocatalysis, flexocatalysis, tribocatalysis, sonocatalysis, each involving specific pathways harnessing at the nanoscale. However, significant challenges arise in decoupling effects related individual mechanism order better understand manipulate their synergies. In review, fundamental principles underpinning MDC are systematically interpreted. Beyond mechanistic insights, recent advancements performance enhancement strategies these catalysts highlighted. Potential applications using approaches remediation (pollutant antibiotic degradation microbial disinfection), conversion (hydrogen production greenhouse gas conversion), biomedical treatments (particularly therapy) discussed. Finally, synergies limiting factors explored, addressing overlooked combined of ultrasound activation source, complexities force interactions nanoscale, need targeted application strategies. Additionally, industrial potential processes with consideration scalability practical deployment is evaluated. While remain, provides a roadmap advancing mechanically catalyst design implementation toward real-world applications, offering into its future trajectory transformative impact across numerous fields.

Multidimensional Engineering of Nanoconfined Catalysis: Frontiers in Carbon-Based Energy Conversion and Utilization

Catalysts, Год журнала: 2025, Номер 15(5), С. 477 - 477

Опубликована: Май 12, 2025

Amid global efforts toward carbon neutrality, nanoconfined catalysis has emerged as a transformative strategy to address energy transition challenges through precise regulation of catalytic microenvironments. This review systematically examines recent advancements in systems for carbon-based conversion (CO2, CH4, etc.), highlighting their unique capability modulate electronic structures and reaction pathways via quantum confinement interfacial effects. By categorizing architectures into dimension-oriented frameworks (1D nanotube channels, 2D layered interfaces, 3D core-shell structures, heterointerfaces), we reveal how geometric constraints synergize with mass/electron transfer dynamics enhance selectivity stability. Critical optimization strategies—including heteroatom doping optimize active site coordination, defect engineering lower barriers, surface modification tailor local microenvironments—are analyzed elucidate roles stabilizing metastable intermediates suppressing catalyst deactivation. We further emphasize the integration machine learning, situ characterization, modular design essential establish structure–activity correlations accelerate industrial implementation. work provides multidimensional perspective bridging fundamental mechanisms practical applications advance carbon-neutral systems.
