Summary:
Iowa State University researchers have developed novel catalysts from commercial organic bases that can be used for economical, rapid, and efficient conversion of glucose to fructose for the food and chemicals industries.

Development Stage:
The catalysts have been demonstrated to convert glucose to fructose with a yield of 31% under mild reaction conditions

Description:
High fructose corn syrup, an important component of a variety of food products, is predominately produced through the enzymatic isomerization of glucose.  While the commercially used enzyme has high yield and selectivity, its turnover rate is very low.  Recent advancements in utilizing tin-impregnated zeolites as catalysts have shown potential for high yield, selectivity and catalytic rate, but have not demonstrated long term stability in hydrothermal reaction environments.  In order to address these issues, ISU researchers have developed a hydrothermally stable carbon-based catalyst that incorporates Brønsted base moieties that have been shown to have comparable performance to the Sn/Beta catalysts in terms of rate, yield and selectivity.  Moreover, these carbon-based catalysts have been successfully tethered to multi-walled carbon nanotubes, resulting in a hydrothermally-stable, heterogeneous catalyst for glucose isomerization reactions.

Advantage:
• Hydrothermally stable
• High yield and fast reaction times
• Cost effective compared to Tin-Beta and solid Brønsted base catalysts
Application:
Brønsted base catalysts for the conversion of glucose to high fructose corn syrup
