The photocatalytic degradation activity of two-dimensional Mo/g-C nanosheets was explored by simulating the ore dressing wastewater with isobutyl sodium xanthate solution. The re? sults showed that the degradation rate of isobutyl sodium xanthate was 90.12% by Mo/g-C nanosheets under the conditions of pH=7Qinitial concentration of xanthate 50 mg/L and degradation time of 6 hQby five times circulationQthe degradation rate can also up to 81.2%.The photocatalysis stability of Mo/g-C is well.
