Researchers at AIST create nanostructured carbon from modified sugars

A research group at AIST has demonstrated a new method to synthesize nanoporous carbonaceous materials using chemically modified sucrose and fructose.

New synthesis method avoids templates

The team developed a process that creates nanostructured materials solely from sugar molecules bearing an alkyl chain. This approach replaces conventional templating methods that require sacrificial agents and complex procedures. The new technique eliminates the need for harsh chemical processes involving high temperatures.

Hydrothermal treatment drives condensation

Modified sugar precursors undergo hydrothermal treatment where condensation reactions take place to form the final structure. This simple process produces materials with highly uniform pore sizes and shapes. The resulting carbonaceous materials can serve as catalyst supports or electrode materials for secondary batteries.
