CoZnFeO4 prepared by waste ferrous sulfate as iron source: synthesis, characterization and photocatalytic degradation of methylene blue

Synthesis and Characterization of Ag-Ag2O/TiO2@polypyrrole Heterojunction for Enhanced Photocatalytic Degradation of Methylene Blue

Hybrid multi-functional nanomaterials comprising two or more disparate materials have become a powerful approach to obtain advanced materials for environmental remediation applications. In this work, an Ag-Ag2O/TiO2@polypyrrole (Ag/TiO2@PPy) heterojunction has been synthesized by assembling a self-stabilized Ag-Ag2O (p type) semiconductor (denoted as Ag) and polypyrrole (π-conjugated polymer) o...

Preparation, characterization and photocatalytic degradation of methylene blue by Fe3+ doped TiO2 supported on natural zeolite using response surface methodology

The photocatalytic degradation of methylene blue was investigated with TiO2 and Fe2O3 nanoparticles supported on natural zeolite. The synthesized photocatalyst was characterized by XRD, XRF, FT-IR, EDX, FE-SEM, and BET analyses. The results of XRD, FT-IR, and EDX confirmed the successful loading of Fe3+ doped TiO2 nanoparticles on natural zeolite. Further, the FE-SEM results confirmed the depos...

Photocatalytic Degradation of Methylene Blue under UV Light Irradiation on Prepared Carbonaceous TiO2

This study involves the investigation of altering the photocatalytic activity of TiO2 using composite materials. Three different forms of modified TiO2, namely, TiO2/activated carbon (AC), TiO2/carbon (C), and TiO2/PANi, were compared. The TiO2/carbon composite was obtained by pyrolysis of TiO2/PANi prepared by in situ polymerization method, while the TiO2/activated carbon (TiO2/AC) was obtaine...

Kinetics of photocatalytic degradation of methylene blue by ZnO-bentonite nanocomposite

The present study reports, the synthesis of ZnO-bentonite nanocomposite by the incorporation of ZnO with bentonite clay. The nanocomposite was characterised by XRD and SEM. ZnO-bentonite was effectively used for removal of Methylene Blue (MB). Removal of MB takes place by photocatalytic degradation and adsorption. Photocatalytic degradation of MB occurs by advanced oxidation process. The factor...
