| Bio-carbon can be prepared from a wide range of raw materials and obtained from most of waste through
carbonization. Bio-carbon is a kind of adsorption material with porous structure and diverse functional groups, which has
application prospects in pollution restoration and soil improvement. This paper reviewed various materials that can be used
to prepare bio-carbon, generalized about the commonly used methods of bio-carbon preparation, and the characterization
characteristics of bio-carbon and summarized the research and application of bio-carbon in repairing polluted environment,
improving soil environment, and as a new type of fertilizer in order to find out the key points and direction of resource
application of bio-carbon preparation from current waste, and made a prospect of the quantitative preparation and largescale application of bio-carbon. |
