Organic sulfur in high sulfur petroleum coke was treated as the S source for synthesis of ZnS photocatalyst. Experimental results showed that with ball milling and subsequent heating treatment, ZnS compound could be successfully synthesized and showed considerable photocatalysis activity for decomposing industrial pollutants. The concentration of methyl orange or ethylene blue may be lowered to less than 5% after being decomposed by the synthesized-ZnS photocatalysis. Results of this study suggested a potential technique of turning high sulfur petroleum cokes from industrial wastes into useful products for environment improvement.
