Silicate‐based chemistry is a common industrial practice to improve peroxide bleaching, however, the transition metal ion‐induced peroxide decomposition is still inevitable. In this study, we investigated the potential to further decrease the peroxide decomposition by adding zeolites to the silicate‐based peroxide system. The peroxide decomposition results showed that the combined effect of zeolites and sodium silicate is more effective than sodium silicate alone in decreasing the manganese‐induced peroxide decomposition. Two types of zeolites, X and Y, were studied. The bleaching experiments showed that an improved peroxide bleaching performance was obtained by adding Y‐zeolites to the conventional peroxide process.
