Properties of amorphous carbon microspheres synthesised by palm oil-CVD method

Amorphous carbon microspheres were synthesized using a dual‐furnace chemical vapour deposition method at 800–1000° C. Palm oil‐based cooking oil (PO) and zinc nitrate solution was used as a carbon source and catalyst precursor, respectively with PO to zinc nitrate ratio of 30:20 (v/v) and a silicon...
