The photocatalysis stride is highly dependent on the design and construction of photocatalysts, marking high activity, and long-term stability. A novel photocatalyst of plasmonic Ag decorated CoWO4/CdWO4 (Ag-CoWO4/CdWO4) tube-like Z-scheme heterojunction was firstly constructed via two-step electrospinning and in-situ deposition approach. Benefiting from the synergistic effects of Z-scheme heterojunctions, 1D tubular structure, and the localized surface plasmon resonance (LSPR) effect of Ag nanoparticles, the Ag-CoWO4/CdWO4 heterostructured photocatalysts showed strong visible-light absorption, high charge separation, and a photocatalytic activity enhancement in levofloxacin (LVF) photocatalysis. Experimental results reveal that ·OH, h+ and ·O2− act as reactive species, promoting and accelerating LVF oxidation. Our work gives the idea of introducing a dedicated composite photocatalyst, conquering individual materials’ intrinsic limits, for wastewater in practical applications.
期刊介绍：
Journal of the Taiwan Institute of Chemical Engineers (formerly known as Journal of the Chinese Institute of Chemical Engineers) publishes original works, from fundamental principles to practical applications, in the broad field of chemical engineering with special focus on three aspects: Chemical and Biomolecular Science and Technology, Energy and Environmental Science and Technology, and Materials Science and Technology. Authors should choose for their manuscript an appropriate aspect section and a few related classifications when submitting to the journal online.
