Studies on the degradation of Congo red compounds using ZnO / zeolite catalysts by photolysis have been done. Congo red compounds are dyes used for textile dyes whose wastes will be harmful to society. ZnO / zeolite is a simultaneous catalyst between degradation and adsorption. From the result of research of 10 mg/L Congo red got a percentage of degradation without catalyst 13.83%, 0.2 g ZnO / zeolite, 0.97%, 0.007 g ZnO, 58.86%, with irradiation time 60 minutes, and degradation of Congo red waste was, 52.68%. The result of degradation of Congo red waste was 52,68% with 60 minutes, irradiation time. The FTIR Congo red analysis shows a shift in the number of waves which means there has been degradation. While the characterization of ZnO/zeolite catalyst by FTIR, XRD, and SEM shows that there is no change of structure of ZnO /zeolite catalyst before and after degradation.
