生物炭制备与应用研究进展OA

Biochar has received wide attention because of its rich indication of functional groups,pore structure,trace alkaline earth metal elements and excellent combustion performance.However,the activity of biochar is affected by many factors,the reaction mechanism is complicated and the selectivity is low.Therefore,this paper summarizes the preparation methods and application scenarios of biochar with the starting point of resource utilization and green chemical industry.The effects of different preparation methods on the activity of biochar are reviewed,and the modification methods of biochar are summarized.Meanwhile,the application examples of biochar in the fields of catalyst,catalyst carrier,environmental treatment and energy chemical industry illustrate its wide application prospects and development potential.Finally,some suggestions are made for the future research direction of biochar.
