The use of mesoporous silica as a template for the nanocasting of metal oxide arrays
… of metal oxide nanowire arrays using the nanocasting approach. This approach utilizes solutions that fill the mesopores of the silica template with a metal salt precursor, which is converted to the oxide by heating to high temperature. The template can be removed by dissolving with an …

Nanostructured Porous High Surface Area Ceramics for Catalytic Applications
… found to be useful as a hard template for the nanocasting of silicon carbide and allowed the preparation of high temperature stable mesoporous silicon carbide ceramics. Chemical vapor infiltration of SBA-15 with dimethyldichlorosilane at elevated temperatures yields SiC/SBA-15 nanocomposites. …

Novel carbon materials with hierarchical porosity : templating strategies and advanced characterization
… templating strategies were developed using the nanocasting approach. The synthesized (monolithic) materials combined for the first time the advantages of a hierarchical interconnected pore system in the macro- and mesorange with the advantages of mesophase pitch as carbon precursor. In the first …

"Reactive hard templating" : from carbon nitrides to metal nitrides
… and macroporous powders could be obtained by nanocasting or nanocoating. Due to the special semi-conducting properties of the graphitic carbon nitride matrix, the nanostructured graphitic carbon nitrides show unexpected catalytic activity for the activation of benzene in Friedel-Crafts type …

Nanostructured carbohydrate-derived carbonaceous materials
… surface functionality were synthesised by the nanocasting of uniform, linear macropores of an AAO template (~ 200 nm). In this example, material porosity could be controlled, showing increasingly microporous tube wall features as post carbonisation temperature increased. Additionally, by taking …

Synthesis and characterization of nanostructured materials for Li-ion secondary batteries
… nanostructured α-Fe2O3 samples were prepared by nanocasting strategy, using different kinds of mesoporous silica (i.e. SBA 15, MCM 41, MCM 48) as hard templates. The selected approach allowed to easily tune the characteristics of the final products. Indeed, opportunely selecting the template …
