Low-temperature solution crystallization of nanostructured oxides and thin films. Chemistry. 2020 Mar 25;: Authors: Bretos I, Diodati S, Jimenez R, Tajoli F, Ricote J, Bragaggia G, Franca M, Calzada ML, Gross S Abstract The increasing demand of high-performance crystalline oxide nanomaterials for applications in current and emergent technologies is pushing research on alternative and sustainable synthesis processes, ideally complying with the principles of Green Chemistry. In this framework, wet-chemistry approaches are particularly promising, since they are typically based on soft synthesis processes, in terms of temperature and pressure, or use water and/or non-toxic alcohols as solvents. Solution methods are low-cost and simple approaches to the synthesis of nanomaterials but, to achieve sustainable, environmentally friendly and competitive manufacturing, they should address an additional target, i.e. the reduction of process energy consumption. This is one of the paradigms of Green Chemistry, where low temperatures and mild conditions of synthesis are specifically pursued. Using low temperatures for the preparation of a nanomaterial or of a nanostructured thin film does not necessarily imply sacrificing crystallinity and compositional purity of the obtained sample. Indeed, low temperatures actually afford tighter control on size and size distribution of the obtained nanostructures and of the microstructure and heterostructure of ...
