A facile citric acid assisted sol–gel method for preparing monolithic yttria-stabilized zirconia aerogel†
Abstract
A facile and general strategy for the synthesis of yttria-stabilized zirconia (YSZ) aerogels was developed by using citric acid as a gelation accelerator. This is a low-cost, nontoxic approach to prepare zirconia based aerogels which have important application potential in catalysis and insulation materials.
