用于能源和环境应用的高度光响应半导体器件需要明智地选择和优化半导体接口以实现宽光谱能力。本工作的目的是合理设计高活性SrTiO 3/g-C3 N4结与Ag/Fe 3 O 4纳米颗粒桥接，利用Z-计划转移和表面等离子体共振效应的银增强氧化铁。采用SrTiO 3/（Ag/Fe 3 O 4）/g-C3 N4（SFC）催化剂在紫外、可见光、近红外和自然太阳光下进行光催化制氢和左氧氟沙星（LFC; 20 mg/L）光降解，表现出良好的性能。在可见光下（
Highly photoresponsive semiconductor photocatalysis for energy and environmental applications require judicious choice and optimization of semiconductor interfaces for wide spectral capabilities. This work aims at rational designing of highly active SrTiO3/g-C3N4 junctions bridged with Ag/Fe3O4 nanoparticles for utilizing Z-scheme transfer and surface plasmon resonance effect of Ag augmented by iron oxide. The SrTiO3/(Ag/Fe3O4)/g-C3N4 (SFC) catalyst was employed for photocatalytic hydrogen production and photodegradation of levofloxacin (LFC; 20 mg/L) under UV, visible, near infra-red, and natural solar light exhibiting high performance. Under visible light (
