Photocatalytic paraquat degradation over TiO2 modified by hydrothermal technique in alkaline solution

Abstract

In the present research, titanium nanotubes were synthesized via the soft hydrothermal method. A study on the effect of the synthesizing parameters such as aging temperature and time of the hydrothermal process on the photocatalytic paraquat degradation was explored. Central Composite Design (CCD) was used to determine the influence of the preparation parameter on the optimal condition, main and interaction effects on crystalline size, percent paraquat removal by adsorption and photocatalytic degradation as responses. The XRD pattern of the synthesized nanomaterial reported the anatase phase of titania nanotubes. SEM image of the prepared nanomaterial clearly indicated the agglomerated with tubular structure. Band gap energy of the nanotubes was found lower than that of the pure anatase TiO

Green Synthesis of TiO2 Nanoparticles Using Averrhoa Bilimbi Fruits Extract and DPT-PEG Polymer Electrolyte for Enhance Dye-Sensitized Solar Cell Application

“…Generally, TiO 2 nanoparticles were prepared using a different type of physical and chemical methods, including microwave method, chemical vapor deposition, solvothermal, hydrothermal, sonochemical method, sol-gel, and electrophoretic deposition [17][18][19][20][21][22][23]. All of these methods are very expensive, require a lot of pressure, a lot of energy, and pollute the environment, whereas the green synthetic method has been found to be more advantageous than the other methods reported.…”

Coprecipitation aided synthesis of bimetallic silver tungstate: a response surface simulation of sunlight-driven photocatalytic removal of 2,4-dichlorophenol

“…To complement the photocatalytic degradation, the present study employed response surface methodology (RSM). RSM is a powerful design tool for developing new processes, modifying the design, and optimizing their performances (Nagaraju et al 2017;Rafaely et al 2021). By systematically adjusting all variables at the same time, it is the most reliable and empirical statistical technique for analyzing the in uence of various process parameters on photocatalytic degradation.…”
