Shuo Chen, Shun‐Feng Jiang, Hong Jiang
Abstract
As a new research focus in the field of biological resources, crayfish shells have great potential for development and utilization. In this review, the typical methods and research progress of separating the primary components such as chitosan, protein, and astaxanthin from crayfish shells and converting crayfish shells into functional carbon-based materials are introduced in detail. Then, the application of crayfish shell and typically modified crayfish-shell biochar in adsorption, antibacterial, electrochemical, etc. is reviewed. Finally, the future research outlook is proposed. This review can provide some perspectives on the development of the application of crayfish shells and crayfish-shell derivatives.
