Step-scheme (S-scheme) heterojunctions have exhibited great potential in photocatalysis due to their extraordinary light harvesting and high redox capacities. However, inadequate S-scheme recombination of useless carriers weak abilities increases the probability with useful ones strong capabilities. Herein, a versatile protocol is demonstrated overcome this impediment based on insertion nano-piezoelectrics into heterointerfaces heterojunctions. Under excitation, piezoelectric inserter promotes interfacial charge transfer produces additional photocarriers recombine electrons holes, ensuring more thorough separation powerful for CO2 reduction H2 O oxidation. When introducing extra ultrasonic vibration, polarization field established, which allows efficient charges generated by embedded piezoelectrics expedites carriers, further increasing number participating reactions. Encouraged greatly improved utilization, significantly enhanced photocatalytic piezophotocatalytic activities CH4 , CO, O2 production are achieved designed stacked catalyst. This work highlights importance strengthening necessary presents an novel strategy synergize piezocatalysis renewable fuels value-added chemicals production.
