•Photoelectrocatalysis was firstly developed without external applied voltage.•It is realized via the assistance of graphene oxide coated thermoelectric device.•Infrared light was converted into electricity by this technology.•This electricity could improve the efficiency of solar light driven photocatalysis.
The infrared light, accounting for almost half of the sun light, has not been utilized effectively by traditional semiconductor-based solar energy conversion technology that is mainly active in the region from ultraviolet to visible light. Thermoelectric device coupled with infrared-active photothermal material provides a unique way to convert the infrared light into electricity. Here we designed a new strategy by coating graphene oxide on a thermoelectric device to realize infrared light generated electricity. By this approach, we successfully achieved harvesting infrared-generated photo-voltage to improve the efficiency of solar light driven photocatalysis via a photoelectrocatalytic process.
