Plasmonic and bi-piezoelectric enhanced photocatalysis using PVDF/ZnO/Au nanobrush

Abstract The photocatalytic degradation, as an environmental-friendly technology, has great significance for cost-effective and efficient catalysis processes, wherein piezo-photocatalysis can significantly increase the catalytic degradation rate using both solar mechanical energy. Here, a ternary heterostructure PVDF/ZnO/Au (PZA) nanobrush photocatalyst with high piezo-photocatalytic efficiency was presented via low-temperature hydrothermal chemical reduction methods. Under energy, current response of as-synthesized PZA all compared that under alone energy alone, excellent recyclability is investigated. It found ultrasonic-assisted completely degrade MO 20 mg/L in 60 min, which exhibits greater enhancement activity than stirring-assisted due to higher power. attributed surface plasmon resonance (SPR) coupling Au built-in electric field originating from ZnO PVDF, absorption visible light, promote charge transfer separation photogenerated electrons/holes. This work introduces SPR bipiezotronic effect improve plasmonic photocatalysis heterostructures, offers new solution green technologies design high-performance catalysts environmental remediation.
