Abstract

The performance of electrogenerated metals supported on HY zeolite (EGZrO2-EGFe2O3/HY) was studied under sunlight irradiation for the decolorization of methylene blue (MB) and Congo red (CR) in aqueous solutions. The prepared photocatalysts were examined using X-ray diffraction (XRD), transmission electron microscopy (TEM), and Brunnauer-Emmett-Teller surface area analysis (BET). An amount of 0.375 g L−1 EGZrO2-EGFe2O3/HY was found to be the optimum dosage for 10 mg L−1 dyes, which gave almost complete photodecolorization of both MB and CR dye after 2 hours of contact time at pH 9 and pH 7, respectively. In addition, a control experiment was also conducted under similar conditions to confirm the efficacy of the prepared photocatalyst. The simple preparation of the photocatalyst and low amount of metal loading required, with simultaneously existence of synergistic effect from both metal oxides exhibits the great potential of the system that could be applied in textile or other industries wastewater treatment.

Abstrak

Keupayaan logam elektrogenerasi disokong pada zeolit HY (EGZrO2-EGFe2O3/HY) telah dijalankan di bawah sinar matahari untuk penyahwarnaan metilena biru (MB) dan Congo merah (CR) dalam larutan akues. Fotomangkin telah dikaji menggunakan pembelauan sinar X-ray (XRD), mikroskopi elektron transmisi (TEM), dan analisis luas permukaan Brunnauer-Emmett-Teller (BET). Sejumlah 0.375 g L−1 EGZrO2-EGFe2O3/HY telah didapati sebagai dos optimum untuk 10 mg L−1 larutan pewarna, yang memberikan penyahwarnaan hampir lengkap bagi kedua-dua pewarna MB dan CR selepas 2 jam tindak balas pada pH 9 dan pH 7. Di samping itu, satu eksperimen kawalan juga telah dijalankan pada keadaan yang sama untuk mengesahkan keberkesanan fotomangkin yang disediakan. Penyediaan yang mudah untuk fotomangkin dan jumlah muatan logam sedikit yang diperlukan, pada masa yang sama dengan kewujudan kesan sinergi dari kedua-dua oksida logam mempamerkan potensi besar untuk sistem ini digunakan dalam industri tekstil atau industri rawatan air sisa yang lain.
