Effect of Ball-Milling on the Surface Characteristics of Nanobiochar

Nanobiochar has received much recent attention among engineered biochars owing to its useful chemical and physical properties. Research efforts have attempted to discover novel methods for nanobiochar preparation and applications. In the present study, a simple cost-effective method for the synthesis ofnanobiochar particles through ball milling using waste materials and by-products was developed. Results showed that process conditions applied to the parent biochar directly influence the properties of the resulting nanobiochar. For instance, over ۷۰% of nanobiochars derived from biomasspyrolyzed above ۴۵۰ °C demonstrated ۳۲ times greater BET specific surface areas than nanobiochars produced at <۴۵۰ °C
