Summary:
Iowa State University researchers have developed a simple, one-step method for producing carbon materials containing multiple, stable catalytic sites that has utility for the production of low-cost heterogeneous catalysts.

Development Stage:
This method has been used for the synthesis of nano-composite materials with ferro magnetic particles with very high (40%) metal loadings that can subsequently be dispersed into thin films.

Description:
Homogeneous acid catalysts are commonly used for the production of industrially important chemicals.  However, despite their low material costs, homogeneous catalysts add cost to the process because of the expense associated with separation, recycling and treatment of the waste sulfuric acid. To address these drawbacks, ISU researchers have developed a low-cost method for the creation of compounds consisting of a carbon backbone with covalently-bonded acid or base groups that have utility as hydrothermally stable carbon catalyst materials.  For example, these materials could be used as strong acid heterogeneous catalysts for reactors operating under hydrothermal conditions, which is important for reactions involving biological feedstocks.  In addition, the technology enables incorporation of a wide variety of functional groups into carbon materials by simply changing the bifunctional reactant.  This technology may also have application in areas such as electrochemistry and electronics since the functional groups can coordinate metal cations, useful for synthesis of nano-composite materials with a range of metals and metal combinations or used as colloidal materials.

Advantage:
• Low cost and simple chemistry
• Covalently-bonded functional groups are stable under hydrothermal conditions
• Both acid and base functionalities can be combined into catalyst at prescribed ratios
Application:
Heterogeneous catalysts
