Photocatalytic Degradation of 5‐Fluorouracil by Diatomite‐Supported Titanium Dioxide under UV‐A Irradiation

Abstract

The aim of this work is the photocatalytic degradation of 5‐fluorouracil from water with titanium dioxide supported on Algerian diatomite. Different methods and amounts of titanium dioxide (30 and 50% weight) are used to synthesize photo‐catalysts which are characterized (X‐ray powder diffraction (XRD), Scanning electron microscopy (SEM), The specific surface area (BET) and X‐ray fluorescence). The degradation efficiency is enhanced by the increasing of TiO2 amount in diatomite matrix. Under our experimental conditions, diatomite supported commercial TiO2 showed the higher performance for the removal of 5‐fluorouracil.

Catalytic Oxidation of Carbon Monoxide over CeO2 and La2O3 Oxides Supported Nickel Catalysts: The Effect of the Support and NiO Loading

“…In particular, based nickel catalysts have also attracted significant devotion in variety of oxidation applications such as hydrocarbon, alcohols and CO [8,9] . Based supported catalysts have recognized very effective in several catalytic and photocatalytic reactions at moderate temperatures, due to synergy between active species and support [10–12] . Supported metal cover the most important class of heterogeneous catalysts in industrial practice.…”

[8,9] Based supported catalysts have recognized very effective in several catalytic and photocatalytic reactions at moderate temperatures, due to synergy between active species and support. [10][11][12] Supported metal cover the most important class of heterogeneous catalysts in industrial practice. Indeed, for supported catalysts, the active sites mainly located on the surface witch the support provides huge surface to separate the active phase and supply the space where the catalytic reactions take place.…”

Deep Characterizations and Rietveld Refinement of Natural Phosphate Mining from Kef Esnoun, Algeria

“…In addition, they are of great importance in the petrochemical industry and environmental science fields. [1,2] Algeria is a country rich in various useful natural materials, most of which are still undeveloped like natural phosphate (noted as NP). In fact, Algeria is one of the world's richest countries in phosphate, with resources of up to 2.1 billion metric tons, whereas the annual mine production was estimated at 1.2 million metric tons in 2019.…”

“…The transformation of natural phosphate into phosphoric acid and fertilizers has widely been applied in certain industrial uses. However, NP can be used in numerous other industrial material applications due to its versatile physico‐chemical properties [1,11–13] . Therefore, detailed physico‐chemical identification of NP is required to find new materials with high performance based on it.…”
