“…Table 2 represents the synthesis techniques and their influential parameters of silicon carbide. Ceballos-Mendivil et al [41] proposed a carbothermic reduction technique that could produce a nanostructure of β-SiC at 1500 • C for 2 h in an argon environment using SiO 2 /C nanocomposite. This has resulted in the introduction of a low-carbon dioxide emission approach that has provided a significant amount of active carbon for composite development and is more thermally stable.…”

Over the past several decades, industrialised and developing nations have attempted to enhance sustainability. Demands for energy and the acceleration in environmental deterioration are the two primary obstacles to progress. The daily generation of municipal solid waste has been a significant factor in the deterioration of the ecology. To address this issue, a considerable amount of municipal solid waste may be used to synthesise SiC nanomaterials from organic and inorganic fractions and use them as carbon and silica sources. Nanomaterials have progressively received widespread prominence as the development of particulate materials accelerates at an incredible rate. One such material is silicon carbide (SiC), which has garnered considerable interest due to its remarkable performance and wide variety of applications. This review article discusses the SiC polytypes, including cubic, hexagonal, and rhombohedral SiC. The characteristics of silicon carbide, such as its biomimetic, surface, and thermal properties, are also discussed. In addition, the synthesis of silicon carbide was described in depth, including microwave sintering, the calcination method, the carbothermal redox reaction, and much more. The final section describes the applications of silicon carbide, including wastewater treatment, medical implants, and gas detection.

“…e XRD pattern generated by 1 mol% Co-1 mol% Ag supported SiO 2 is shown in Figure 1. e wide peaks between 18°and 40°associated with the crystalline phase are not revealed as it was intended for an amorphous structure [34][35][36]. Based on the XRD study, the amount of the doped metal does not affect the amorphous structure of silica.…”

Co-Ag supported on the SiO2 catalyst was synthesized by the sol-gel method and characterized using XRD, FT-IR, TG-DTG, BET, CV, and SEM/EDX analysis. The catalytic performance of the resulting catalyst was examined by the oxidation of mono and sesquiterpenic olefins using hydrogen peroxide and tert-butyl peroxide as oxidant agents. Various parameters such as catalyst amount, temperature, and solvents have been studied. The Co-Ag supported on the SiO2 catalyst showed a high activity, selectivity, and recyclability for the selected oxidation reaction.

“…A square honeycomb SiCSi structure usually used in CSP plants as an absorber material was thermally treated and thermoradiative properties were recorded [21]. Ceballos-Mendivil et al [22] synthesized silicon carbide, in five steps, using solar energy in the last two with lower CO 2 emissions during the process.…”

Polymer-Cement Composites Glazing by Concentrated Solar Energy

et al. 2021

Macro defect free (MDF) cements are polymer-cement composites characterized by high biaxial flexural strength compared to traditional concrete, having as a drawback a low water resistance. Glazing these composite materials with an inorganic enamel containing TiO2 nano-particles has led to a high water-stable material with advanced photocatalytic properties. Classic glazing by thermal treatment of samples, at 1050 °C, requires energy consumption and long-time performing. The purpose of this paper is to test the use of solar radiation as a source of energy in the glazing process. A vertical axis solar furnace has been used, from PROMES-CNRS Solar Laboratory, Font-Romeu Odeillo, France, and it has been observed that a uniform appearance of the glaze coating has been achieved; it shows high scratch resistance, meaning a good hardness and adhesion to the substrate. The obtained film was also characterized by SEM, EDS and XRD, aiming to evidence the coat morphology, the TiO2 distribution and its crystallinity alteration, when compared to the samples obtained by classic thermal treatment. The conclusion of the paper is that using solar radiation in the MDF cement glazing process is a promising approach for obtaining multifunctional materials.
