Abstract:
Herein, we present a visible light assisted high-performance H 2 gas sensor based on a Pt-modified WO 3 nanosphere structure. The obtained results show that the Pt–WO 3 nanospheres have a higher response, faster response/recovery time, and better selectivity than pure WO 3 . At 109 °C, the Pt–WO 3 nanosphere structure exhibits a response of 80.49 to 5 ppm H 2 , which is 80 times higher than that of pure WO 3 nanospheres. The irradiation of visible light lowers the power consumption of the sensor. H 2 response is improved through the introduction of all visible light wavelengths. Under visible light ( λ = 530 nm) illumination at 109 °C, the response of nanosphere structure elevates to 133.71 for 5 ppm H 2 . Additionally, the H 2 gas-sensing mechanism of the Pt-modified WO 3 nanosphere structure sensors under visible light illumination is discussed.
