A highly N-doped carbon phase "dressing" of macroscopic supports for catalytic applications.

The straightforward "dressing" of macroscopically shaped supports (i.e.ß-SiC and α-Al2O3) with a mesoporous and highly nitrogen-doped carbon-phase starting from food-processing raw materials is described. The as-prepared composites serve as highly efficient and selective metal-free catalysts for promoting industrial key-processes at the heart of renewable energy technology and environmental protection.
