Summary: This study demonstrates the improved thermoelectric performance of Bi2Te3 nanosheets grown on reduced graphene oxides (rGO) through the formation of heterointerfaces. The phonon scattering effect and extra carrier transport channels induced by the rGO-Bi2Te3 heterointerface lead to an enhanced power factor value and reduced thermal conductivity. Furthermore, the photo-thermoelectric catalysis of rGO-Bi2Te3 significantly increases the yield of reactive oxygen species. This study provides new insights into heterointerface design in photo-thermoelectric catalysis.
