| 6. Conclusions and Future Prospects
In this review paper, synthesis, characterization mecha- nisms, and application areas of biosilica were reviewed. Agricultural waste resources such as palm tree, wheat straw, maize leaves, tef straw, sugarcane bagasse, rice husk, rice straw, sugarcane leaf, oat husk, bamboo leaf, and corn cob can be used as a source of silica was presented. From these biomass sources, using diferent approaches such as sol-gel, hydrothermal, chemical vapor deposition, impregnation, electrodeposition, coprecipitation, and leaching method synthesizing of silica gel have been described briefy. Ten, using diferent characterization mechanisms such as BET, XRD, TEM, and SEM were presented. Also, the multipur- pose applications used in the form of catalyst, synthesis of shear thickening fuid, chemically inert material, strong adsorption capacity, ceramics, concrete materials, glass, cement, medicine, supercapacitors, batteries, cosmetics, detergents, adhesive agents, pharmaceutical, fne-chemicals, clean fuels, catalyst support, microflters, thermal super- insulation, controlled release of drugs, and good option to deliver drugs of antibiotics were presented here. Tis review indicates that the results from agricultural wastes source of silica is an alternative one. Terefore, this form of silica basis will contribute benefts used for a low-cost input material, pure silica product, and environmentally-friendly. Besides these, the subsequent features have a necessity to be addressed in upcoming mechanisms: (1) advance studies on agricultural leftover resulting biosilica in order to grow better-quality fresh adsorbent on behalf of removing organic and inorganic wastes from drinking and wastewater. (2) Development of a high-yield and cost-efective biosilica which replace an energy-intensive commercial sale product. (3) Biosilica products have their own merits such as the raw materials that are easily available, cost-efective, pure yield, and environmentally-friendly. (4) Te merits and demerits of each preparation method of biosilica are still not clear. Consequently, scientists are quite challenged with in- complete consideration in this zone of biosilica preparation. On behalf of the advance argument on this fact of view, the reader can denote the reference presented now. (5) In emerging requirements for silica, there is an essential behalf of critical care over the outline of favourable directive that encourages the vast usage of used yields after leftover. tải về 1.86 Mb.
