Piezocatalytic generation of H2 is an emerging technology for the collection and application mechanical energy efficient production sustainable nowadays. To enable high-efficiency low-energy H2, we prepared three MoS2-based composites (MoS2/ZnO, MoS2/CuFe2O4, MoS2/ZnO/CuFe2O4) used them as catalysts green synthesis under mild magnetic stirring conditions (namely, hydraulic driving) to replace conventional ultrasonic vibration. MoS2/ZnO/CuFe2O4 displayed highest piezo-photocatalytic activity with a notable rate 3963 μmol g–1 h–1 in 10 vol % methanol–water mixture, accompanied by 1436, 3325, 2538 MoS2, MoS2/ZnO, respectively, at speed 400 rpm (hydraulic gradient, 0.123 s–1) 50 W light irradiation. A series characterizations analyses were performed comprehend insight into catalytic difference related reaction mechanisms. The improved performance can be ascribed enhanced absorption capability, reduced electron transfer resistance, separation efficiency charge carriers, all which are conducive evolution. Holes played major role generation. over was far higher than reported values obtained using ultrasound-driven piezocatalytic slurries. delivery also achieved lower consumption values. In comparison experiments this work, hydraulic-driven catalysis characterized remarkably requirements, less noise pollution, stronger structural stability catalysts. This study provides method renewable energy.
