Reutilization of silicon- and aluminum- containing wastes in the perspective of the preparation of SiO2-Al2O3 based porous materials for adsorbents and catalysts

XPS characterization of cobalt impregnated SiO2 and γ‐Al2O3

“…5,6 Furthermore, silica and alumina supports can be obtained from wastes containing silicon and aluminum, which could lead to obtaining catalysts in environmentally friendly reutilization processes. 7 Cobalt is a very interesting metal to be used as a component in multimetallic catalyst in different chemical reactions. The oxidationreduction properties of cobalt allow for different oxidation states, as electrons can be easily transferred between reactants and cobalt catalysts.…”

Nanomaterials with Tailored Magnetic Properties as Adsorbents of Organic Pollutants from Wastewaters

“…Within the framework of the circular economy, several efforts have been made to add value to wastes, converting them into renewable raw material for the production of fine, bioplastic and auxiliary chemicals for technological and environmental applications. In particular, the modification of different industrial and household wastes into adsorbent materials has been the subject of much research, since it represents an economically sustainable method of waste valorization [128][129][130]. Among them, the most common are agricultural residues, for example the skin of different fruits and vegetables, remnants of branches and leaves, remnants of rice, corn, olive and many others.…”

Preparation and characterization of tubular cermet membrane for microfiltration separation: application to the treatment of textile wastewater

“…Therefore, the purpose of this study was to join the recent efforts of researchers such as Hamden et al [11], Sayehi et al [12], and Abid et al [13] to valorize this environment pollutant by transforming it into a filtration membrane that can alleviate the dangers of the contaminating textile effluents. To reach this objective, this study purported to design a membrane made of ceramics and metal, called cermet, that would be capable of treating the contaminated effluents to a satisfactory level.…”
