Aerogels, which have highly porous nanostructures that contain 90%–99% air by volume, are considered as a very attractive option in various applications. The potential of utilising agricultural and industrial wastes for aerogel preparation makes them more interesting. Its high surface area and porosity could make it an interesting material for water vapour or other gases adsorption. Despite its promising potential as a desiccant, only a few research studies were conducted to investigate aerogel as a desiccant material. This study attempted to present the essential concepts and studied research on aerogels as desiccant materials to illustrate the achieved goals, current limitations, and future opportunities.

气凝胶作为干燥剂的前景：可能性与挑战

气凝胶具有高度多孔的纳米结构，按体积计包含90％至99％的空气，被认为是各种应用中非常有吸引力的选择。利用农业和工业废物制备气凝胶的潜力使它们更加有趣。它的高表面积和孔隙率使其成为用于水蒸气或其他气体吸附的有趣材料。尽管其潜在的干燥剂潜力，但仅进行了少量研究来研究气凝胶作为干燥剂。这项研究试图提出基本概念，并研究了作为干燥剂的气凝胶的研究，以说明已实现的目标，当前的局限性和未来的机遇。
