Abstract

Abstract: In recent years, the amount of agricultural and industrial wastes being generated is increasing rapidly. This leads to numerous disposals, governance, and environmental issues. Therefore, the re-utilisation of these wastes into value-added products such as mesoporous silica nanoparticles (MSNs) has attracted great attention. MSNs have garnered immense attention in various applications owing to their tuneable pore dimensions, high surface areas, and tailorable structure, suitable for different post-functionalisation. In this review, recent progress on the synthesis of MSNs from waste using a chemical synthesis route is presented. This route offers the possibility to control silica structure, phase, morphology, and sizes by fine tuning the reaction parameters/conditions. The characteristics and applications of the MSNs produced are also analysed to examine the potential of using agricultural and industrial waste as the silica precursor. Although the use of inexpensive waste-derived materials seems promising for both waste reduction and value-added products synthesis, further research is still needed to boost the production of silica especially at a larger scale. Graphical Abstract: ga1 Highlights: The use of agricultural and industrial waste for silica synthesis. Chemical synthesis routes produce high purity silica. Influence of acid leaching treatment on the impurity removal and silica production. Hydrothermal, co-precipitation and sol-gel techniques were discussed. The effect of reaction parameters on the silica properties.
