Key Points

To explore the effect of single-atom rhodium on BaTiO3 for improving piezocatalytic H2O2 production.
Utilized surface-anchored rhodium single atoms on BaTiO3
Measured piezocatalytic H2O2 production rates
Analyzed oxidation kinetics associated with rhodium sites
Achieved a 1.5-fold increase in H2O2 production
Observations indicate acceleration of oxidation kinetics
Found that these sites enhance piezocatalytic performance

Abstract

Surface-anchored rhodium single atoms on BaTiO 3 enhance piezocatalytic H 2 O 2 production by 1.5-fold. The atomic rhodium sites accelerate oxidation kinetics rather than reduction, providing a unique design strategy for high-performance piezocatalysis.
