Abstract:

Bismuth oxyhalides (BiOX, X= Cl, Br and I) and their composites have been successfully synthesized using different leaf extracts. Leaf extract is known to possess anti-oxidant and stabilizing properties that aids in the immediate reduction and stabilization of the metal ions into their corresponding nanostructures. To obtain a better understanding of the results, the BiOX and their composites were also synthesized by hydrolysis method (without leaf extract) followed by their immobilization on Alumina (Al2O3)-based ceramic fiber sheet and activated carbon block as supporting material. The main objective of the present work was to eliminate the separation problem of the powder photocatalysts from the aqueous medium and evaluate their efficacy for the photocatalytic disintegration of organic contaminants in the long run. The synthesized photocatalyst was characterized using SEM, XRD, FTIR, UV-vis DRS etc, which suggested that the BiOX were successfully embedded in the host matrix of ceramic fibers and carbon block. The results revealed that the higher pH value was more favorable for bisphenol A (BPA) and Ampicillin (AMP) degradation, while the MO was completely degraded at all pH range. Moreover, the stability test was performed, and high stability of the immobilized samples was observed for five cycles without leaching out in the aqueous medium. The present study could offer new outcomes for advancing the large-scale applications of supported materials for environmental remediation. Recent Publications 1. Harshita Chawla, S.
