AI Technical Summary
Existing technologies make it difficult to efficiently recover tin oxides from tin sludge and apply them to H2S sensing materials. Furthermore, the preparation process is complex and costly, which is not conducive to industrial production, and the tin resource shortage problem is serious.
Sulfur-containing SnO2 materials were prepared by activating tin mud through acid washing combined with solvothermal method, and Ni/S-SnO2 sensitive materials were prepared by surface modification of metallic Ni for use in low-concentration H2S gas sensors.
This technology enables the green recycling of tin oxides, reduces enterprise costs, improves the sensitivity of H2S gas sensors, aligns with the concept of green development, and enhances the porosity and surface area of the material.
