Photodegradation of Malachite Green Using Immobilized TiO2 and Factorial Design

Abstract

The effect of the variables: initial pH (4-10), concentration of the dye (3-17 ppm), irradiation wavelength (254-360 nm) and sustrate: H

Characterization of a highly efficient N-doped TiO2 photocatalyst prepared via factorial design

“…[39][40][41] In photocatalysis, they have been used mainly on the investigation of the synergic interactions of key physicochemical parameters that affect the photocatalytic efficiency (pH, reaction times, relative concentrations etc.). [42][43][44][45][46][47] Only in a few works in the literature, chemometrics tools have been used to evaluate the synthetic parameters employed in the photocatalyst preparation. 48 In the present study, we have used experimental factorial design (screening and response surface experiments) to identify the most important synthetic variables that affect the photocatalytic activity of N-doped TiO 2 catalysts.…”
