Hollow TiO₂–SiO₂ Nanospheres for Photocatalytic Degradation of Organic Dyes

ACS Applied Nano Materials, Journal Year: 2024, Volume and Issue: 7(3), P. 2630 - 2638

Published: Jan. 18, 2024

Water pollution is a serious problem in both developed and developing countries. Several methods have been used to purify wastewater, among which photocatalytic decomposition widely organic pollutants wastewater. In this work, hollow nanospheres of titanium dioxide TiO2 were first prepared by the carbon sphere template method sol–gel method, then, (TiO2) compounded with silicon (SiO2) impregnation generate complexes different ratios nanoparticles dioxide. The best degradation performance h-TiO2/SiO2 materials was achieved when ratio h-TiO2 SiO2 5:1. cyclic efficiency 5:1 composites showed only slight change capacity compared cycle, thus ensuring durability samples. However, quenching experiments yielded that hydroxyl radicals play major role process, possible reaction mechanisms are discussed detail. high environmentally friendly nanosphere photocatalysts makes them ideal for water purification applications offers potential utilization solar energy effectively reduce environmental pollution. nanophotocatalysts can not degrade dyes but also be valuable self-cleaning glass applications.

Published: March 22, 2024

This article describes an affordable method for the synthesis of MnMoO4 nanoflowers through microwave approach. By manipulating reaction parameters like solvent, pH, power, and irradiation duration along this pathway, various nanostructures can be acquired. The synthesized were analyzed by using a powder X-ray diffractometer (XRD), field emission scanning electron microscopy (FE-SEM) with energy dispersive spectroscopy (EDS), Fourier transform infrared (FT-IR), UV–vis diffuse reflectance (UV–DRS) to determine their crystalline nature, morphological functional group, optical properties, respectively. photoelectron (XPS) was performed examination elemental composition chemical states qualitative quantitative analysis. results investigations demonstrated that good crystallinity distinct shape formed successfully. tested efficiency as photocatalyst in degradation studies methylene blue (MB) model organic contaminants aqueous medium under visible light, which showed photocatalytic activity 85%.
