Abstract Effective and recyclable water treatment technologies are crucial for practical heavy metal removal. Photocatalysis an improved oxidation process is widely used in energy production environmental remediation. However, the reaction efficiency of photocatalysis restricted by rapid recombination photogenerated electron–hole pairs, although it promising under solar light illumination conditions, remains challenging because seasonal variations, weather diurnal cycles. Alternatively, piezo catalysis, transferring mechanical to chemical energy, vital cleansing regeneration. Therefore, lead zirconate titanate (PZT) with a MgAl layered double hydroxide graphene oxide (GO) prepared herein efficient piezo‐photocatalytic. The proposed material PZT‐MgAl‐GO combination UV sonication remove hazardous metallic Cr(VI) species. reduction efficiencies increase order PZT<MgAl‐GO<PZT‐MgAl‐GO. amount decreases ≈99% through involving both exposure. main active species photocatalytic assumed be e − •O 2 radicals. With these advantages high decomposition ratio, simple preparation method, its use considered potential removing metals from wastewater.
