Breakthrough in Nanotechnology: Boosting H2O2 Synthesis for Fenton Oxidation Process

Strategic Insights -

Scientists at the Beijing University of Technology have made a significant breakthrough in nanotechnology, developing a novel piezo-photocatalytic system that enhances charge kinetics related to photogenerated charge separation and transfer. This innovation involves the construction of a supramolecular bi-metallic copper/zinc tetrakis (4-carboxyphenyl) porphyrin and zinc silicate heterojunction, which amplifies piezoelectric response under ultrasonication and facilitates a Z-scheme electron transfer. The research has demonstrated a high apparent quantum efficiency of 45.09% at 420 nm under concurrent ultrasonic and light irradiation, and enables high-efficiency degradation and mineralization of antibiotics, such as ciprofloxacin.
