▎ 摘　　要

NOVELTY - A nanopore ordered copper-doped tin oxide sensor is prepared by preparing graphene oxide/interdigital electrode by using 0.01-10 mg/ml polar graphene oxide solution. The pH of the polar graphene oxide solution is adjusted. The polar graphene oxide solution is spin coated on graphene oxide film and interdigital electrode, followed by preparing sensing device by dissolving copper salt and tin salt in polar solvent, adding surfactant, and regulating pH to obtain clear solution, which is spin-coated on a sensing material, dried, and subjecting to under UV irradiation and reduction reaction. USE - Nanopore ordered copper-doped tin oxide sensor for sensing hydrogen sulfide gas. ADVANTAGE - The tin oxide sensor has better sensing performance, and reduced low concentrations of hydrogen sulfide gas response time and recovery time. DETAILED DESCRIPTION - A nanopore ordered copper-doped tin oxide sensor is prepared by preparing graphene oxide/interdigital electrode by using 0.01-10 mg/ml polar graphene oxide solution. The pH of the polar graphene oxide solution is adjusted to 9-10. The 0.01-10 mg/ml polar graphene oxide solution is spin coated on graphene oxide film and interdigital electrode, followed by preparing sensing device by dissolving copper salt and tin salt in polar solvent in mass ratio of 1: 100-8: 100, adding surfactant, and regulating pH to obtain clear solution. The clear solution is spin-coated on a sensing material, and dried under hot steam for 1-4 days. The device is subjected to under UV irradiation and reduction reaction to obtain a finished product.
