SYNTHESIS OF NOVEL HIGHLY POROUS CuS GOLF BALLS BY HYDROTHERMAL METHOD AND THEIR APPLICATION IN AMMONIA GAS SENSING

A novel kind of porous CuS golf balls with an average diameter of 2 µm have been successfully synthesized by using CuCl powders as source PVP as soft template based on a template-directed approach. This process involves the conversion of CuCl to CuS via reaction with H2S, which is produced by hydrol...
