Description
Summary:Nanocasting is a powerful method for creating materials that are more difficult to synthesize by conventional processes. We summarize recent developments in the synthesis of various structured porous solids, covering silica, carbon, and other nonsiliceous solids that are created by a nanocasting pathway. Structure replication on the nanometer length scale allows materials' properties to be manipulated in a controlled manner, such as tunable composition, controllable structure and morphology, and specific functionality. The nanocasting pathway with hard templates opens the door to the design of highly porous solids with multifunctional properties and interesting application perspectives. The nanocasting pathway from hard templates, a versatile synthetic strategy, has successfully been applied for the creation of porous solids (see figure). The obtained structures can be precisely tailored by selecting a suitable template, precursor, and synthetic conditions, and the resulting materials lend themselves to further, spatially controlled modification.
