After ball milling (BM) in a jar with a vibration frequency of 1800 r/min for 15 mins followed by a washing step, a black product (Co-BM-C) was obtained. To investigate the reaction kinetics, the product yield was first investigated based on different milling time (5–30 min). As a result, the highest yield was reached only after 15 mins ...
