Simple SummaryContent extracted from patent full text and abstract with AI.

This invention discloses a novel method for producing metal-containing, spherical, porous carbon particles. The process involves polymerizing a carbon precursor with a structural template in a solvent, adding a metal compound to the resulting polymer solution, and then forming the particles via aerosol spray and thermal treatment. The method enables uniform distribution of metal nanoparticles within the porous carbon spheres, which can be further processed into inks and serve as catalysts, especially for various chemical and electrochemical applications.

Patent Abstract

The invention relates to a process for producing metal-containing spherically porous carbon particles. To this end it is preferable when in a first step a carbon precursor is polymerized with a structure-forming template in a solvent to afford a polymer solution, in a second step the metal compound is added to the polymer solution and finally in a third step the metal-containing spherically porous carbon particles are formed by an aerosol spraying process. The invention further relates to a process for producing an ink and to a use of the metal-containing spherically porous carbon particles as catalyst.
