Abstract: Biochar,produced by the thermal decomposition of various biomass sources,is applied in different fields of research due to its distinctive properties. With the recent explosion of methods for a large-scale synthesis of biochar,the number of literatures relevant to biochar and biochar based materials has increased exponentially. This review exclusively focuses on the current development of biochar based functional catalysts,and applications in（trans）esterification. Thus,this review firstly presents a brief description of the design and synthesis of the biochar based catalyst,and then summaries the applications of these biochar based catalyst based upon（trans）esterification. Finally,the current advances and the future perspectives of the biochar catalyst is presented. Hopefully,this review will offer a perspective and guidelines for the future research and development of biochar based catalysts for biodiesel production.
