Via catalyst‐assisted pyrolysis, Si3N4 and SiC nanowires were produced on the cell walls of polymer‐derived ceramic foams. The pyrolysis atmosphere and temperature were the main parameters affecting their development: silicon nitride single‐crystal nanowires formed under nitrogen, while silicon carb...
