Thermoelectric Methylene Blue Degradation by SnSe-Doped Low-Content Copper

In important applications, thermoelectric technology has been widely applied for precise temperature control in intelligent electronics. This work synthesized and characterized low-content copper-doped SnSe thermoelectric catalysts using an easy and effective hydrothermal method. It was discovered that doping increased the crystal plane spacing of SnSe, increased the carrier concentration, and improved the thermoelectric properties. The best degradation was attained at x = 0.0025. The thermoelectric degradation performance of low-dose copper-doped tin selenide Sn1−xCuxSe (x = 0, 0.0005, 0.001, 0.0015, 0.002, 0.0025, 0.003), for the degradation of methylene blue from organic wastewater at 75 °C, was examined. Our research indicates that by using this approach, we can create more high-performance catalysts.
