Process conditions for the manufacture of highly micro-mesoporous eco-friendly activated carbon from artocarpus integer bio-waste by steam activation

In this paper, for the first time, we report the process conditions to obtain highly micro-mesoporous eco-friendly activated carbon (Eco-AC) from Artocarpus integer bio-waste by steam activation. The proposed novel material provides a green alternative to existing chemically activated bio-wastes for...
