Abstract: Fabricated halloysite and halloysite supported Fe-Ni (Fe-Ni@HNTs) nanostructure is successfully fabricated by immobilization of precursor metal over the surface of amino siliane modified HNTs. The as-sythesized HNTs supported metal nanostructures were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM) and energy dispersive X-ray spectrometry (EDX). Peaks patterns obtained from XRD confirm the formation immobilized HNTs and Fe-Ni@HNTs.12 mol % Fe-Ni@HNTs shows better photocatalytic oxidation of methylene blue (MB) than 6 mol % Fe-Ni@HNTs under the influence of UV irradiation. The effect of loading of catalyst had also been studied under this report.
