“…The resulting materials scored an impressive specific quantity capacity value of 9.88 mAh g −1 , while the specific capacitance of the derivatized carbon material prepared with CFA-FumMOF as precursor displayed a significant value of 306.59 F g −1 under the same conditions, providing a feasible path for high-value reuse of solid wastes [83]. Yuan's group [84] prepared MIL-53(Al) by employing high alumina coal fly ash (HAFA) and its sintered product obtained by alkali melt activation reacted with terephthalic acid in a one-pot process, respectively, and proposed the concept of ecological MOFs (eco-MOF). The synthesized eco-MIL-53(Al) maintained a firm backbone at 500 • C. The surface area and pore volume of eco-MIL-53(Al) treated with hydrochloric acid can reach 16.3 m 2 g −1 and 0.075 cm 3 g −1 , respectively.…”

Coal fly ash (CFA) is the primary solid waste generated by the coal-fired industry, and the predominant treatment methods include accumulation, landfill, and the production of cement-based building materials. However, the availability of these methods is relatively limited, and there is a need for technological upgrades. The extensive accumulation not only leads to environmental pollution but also has detrimental effects on human health. With its loose structure and main chemical components of Al2O3 and SiO2, CFA is conducive to the synthesis of promising nanoporous materials for applications in adsorption. The use of CFA as a raw material can significantly reduce preparation costs, improve comprehensive utilization efficiency, and manufacture more valuable products, aligning with the current strategy of sustainable development. Currently, the most widely used synthesis method is hydrothermal synthesis. This review focuses on the principles, methods, and influencing factors of synthesis, with particular emphasis on CFA-based mesoporous silica, zeolites, and metal–organic frameworks (MOFs), which have not been systematically reviewed previously. The quality of these synthesized nanoporous materials can be finely adjusted through the synthesis process. A comparison of the advantages and disadvantages of each process will be made, and the impact of the synthesis conditions on the synthetic products will be analyzed. Additionally, a brief discussion on the latest research advances in their applications in adsorption will be provided. Finally, relevant challenges and issues have been proposed.

“…Due to the stable mineral phases of mullite and quartz contained in the y ash, 8,9 it is difficult to extract Al, Si and other resources efficiently. 10 So far, several processes have been reported to extract valuable metals from coal y ash, including the soda-lime sintering process, 11,12 ammonium sulfate sintering process, 13 alkaline leaching 14 and acid leaching process, 15 etc. Metallurgical grade alumina could be produced by soda-lime sintering process, which has the disadvantages of high-energy consumption and large slag discharge.…”

“…Agriculturally based industries produce a lot of garbage as a result of their operations. Non-consumable plant portions are referred to as agro-waste, while edible parts are the primary source of energy for humans [4]. Biological oxygen demand (BOD), chemical oxygen demand (COD), and suspended solids are all significant in this vast volume of agro-waste [5].…”

Biogeneration of Valuable Nanomaterials from Agro-Wastes: A Comprehensive Review

et al. 2023

View full text Add to dashboard Cite

The exponential growth of agricultural output is a result of the increasing world population. Agro-wastes are now acknowledged as an alternative material for the manufacture of renewable, inexpensive, and sustainable bio-composite-based products. Huge amounts of agricultural produce are often lost owing to a lack of processing facilities or storage space. Agriculture wastes contain a significant concentration of carbohydrates as well as various multifunctional groups and organic substances, such as polymeric proteins. Interestingly, nanotechnology provides better potential to transform agricultural wastes easily into valuable and cost-effective products, removing the need to utilize noxious chemicals, which can create a variety of health and environmental difficulties. Recently, there has been an increase in interest in eco-friendly nanomaterial (NM) production techniques that utilize extracts generated from agricultural waste. Such nanoparticles (NPs) have been extensively studied for numerous uses, including antibacterial agents, water purification, the breakdown of industrial colours, and many others. Consequently, the purpose of this review is to investigate the different sources, characteristics, and nano-management of agro-waste; valuable NMs derived from agro-waste; and their possible applications.
