Review of biochar structure and physicochemical properties

As a new emerging technology, biochar and its applications have been rapidly developed in recent years. However, due to large differences in carbonization materials and processes, it is difficult to compare or even contrast the results of biochar application studies, thus hindering the development of biochar applications to some extent. For this reason, our paper focuses on the key factors restricted the function of biochar, namely, the structure as well as physical and chemical properties of biochar, and then systematically presents the main research advances in recent years from the following perspectives of biochar such as definition, formation, structure, elemental composition, and other main physical-chemical properties, and property controlling-technologies. The paper analyses and summarizes the common and differential characteristics of biochar structure and physical and chemical properties and clarifies the relevant basic perspectives, statuses, trends, and consensus on the structure and properties of biochar. The structure and fundamental physical and chemical properties of biochar are believed to be the most important factors affecting the roles, function, and effects of biochar. They also determine the application field, scope, amount, objective, and direction of biochar. Therefore, the modification technology or optimal regulation technique is the key to develop the efficacy advantage, potential and values of biochar. By further combining the research and application of biochar, the basic principles and development directions of biochar physicochemical property research in the future focusing on the physical and chemical properties of biochar are evaluated from cycle and sustainable development of resources and material perspectives. This paper aims to provide the basis and reference for the development of basic scientific science and application technology studies on biochar.
