“…In parallel with the first two methods, we have successfully synthesized several nanosized particles of ␣-Fe 2 O 3 , ZrO 2 , ZnO, CuO, and ␣-FeOOH supported on zeolites or silica by a simple electrochemical method [7][8][9][10]. Their outstanding uses as photocatalysts in the photodegradation of organic pollutants as well as in isomerization encourage additional modification.…”

“…The band at about 983 cm 1 in the spectra of FAZ-X (Figure 2(b)) is shifted to high wavenumber 1075 cm 1 (Figure 2(c)) indicative of exchanging Na + by Cu 2+ cations [27,28]. All the above-mentioned peaks, except the broadband at 1075 cm 1 , appear either weak or overlapped/merged with neighboring peaks or shifted to higher wavenumber side in CuO/FAZ-X (Figure 2(c)) [29,30]. Thus, IR spectra provide evidence for zeolite formation from PFA, and then CuO/FAZ-X from FAZ-X.…”

Abstract. Copper oxide incorporated y ash-derived zeolite X (CuO/FAZ-X) was synthesized from solid waste coal y ash by ion exchange with Cu 2+ followed by calcination process. The synthesized materials were characterized by XRF, FTIR, SEM, EDX, and BET methods. In the application of the catalysts for wet peroxide oxidative decolorization of the model dye MB (Methylene Blue), the e ects of major parameters, such as CuO loading, initial H 2 O 2 concentration, initial dye concentration, catalyst dosage, and pH, were investigated to assess the activity of the catalysts. In comparison with the activity of either y ash-derived zeolite X (FAZ-X) or CuO, the combined catalyst (CuO/FAZ-X) showed an enhanced wet catalytic activity. Under the optimal condition (catalyst dose 250 mg/L, 100 ppm dye, pH = 6.8, 1 ml H2O2, and room temperature or 30 C), the decolorization of MB was about 100% in 120 min by CuO/FAZ-X and only 31% and 44% by FAZ-X and CuO, respectively. Based on the decolorized products identi ed by HPLC-(-ESI)-TOF-MS, the decolorization pathway of MB was proposed. Consequently, incorporation of CuO remarkably improved the catalytic activity of FAZ-X, such that CuO/FAZ-X emerged as a novel, reusable heterogeneous Fenton-like catalyst for oxidative decolorization of model dye MB. Thus, the present work demonstrates a simple and facile route for the conversion of waste coal y ash into a valuable catalyst.
