CONTEXT

Due to numerous benefits porous carbon materials offers (high specific surface, high pore volume, surrounding chemicals insensitivity and good mechanical properties), these materials are highly interesting for many applications. There are currently a high number of processes leading to such materials but all of them involves disadvantages. There is nowadays a demand for easy one-step process leading to such material.

TECHNICAL DESCRIPTION

In the present work, the inventors have developped an easy one-step process to prepare a porous carbon material mixing Pyrolysis and Boudouard equilibrium from oxocarbones (and especially from squaric acid, ie starting material (I-7) with R21=R24= OH and R22=R23=O).

Material’s characteristics:

• Sp2 carbon configuration;
• Interconnected pores (size 40A);
• Specific surface (BET) 750 m²/g;
• Expanded foam (monolithic);

​

DEVELOPMENT STAGE

• Suitable process for multi-gram scale synthesis;
• Electrochemical tests;

BENEFITS

Apart from the material’s own advantages such as a high specific surface, high pore volume, surrounding chemicals insensitivity and good mechanical properties, the process is easy to set up, fast, non expensive and non toxic. 

INDUSTRIAL APPLICATIONS

Porous carbon materials can be used in numerous applications:

• Electrodes, electrochemical storage;
• Light wave detection device; 
• Separation chemistry (chromatography,…);
• Heterogeneous catalysts; 
• Absorbant materials.
