摘要：
Novel ZnS/CuS nanocomposites with different mole ratios were successfully prepared by the cation exchange reaction and characterized by AAS, FTIR, SEM, and EDX. The catalytic activities of ZnS/CuS nanocomposites were evaluated against the oxidation of thymol (T) at room temperature in acetonitrile. The obtained ZnS/CuS (20% and 50% Cu) nanocomposites exhibited excellent catalytic activity (100% conversion and selectivity in 60 min. and 20 min., respectively) using tert-butyl hydroperoxide (TBHP) as an oxidant. Recycling studies of the nanocomposite showed high conversion values throughout four catalytic cycles (four cycles with 98% conversion in 4 h). [GRAPHICS] .
