Recent research development of hierarchical porous carbon in capacitive deionization
This review comprehensively introduces and summarizes the roles of various pore structures and the research progress on different hierarchical porous carbon(HPC)materials used as capacitive deion-ization(CDI)electrodes.The study also highlights the challenges faced by HPC as a CDI electrode mate-rial in practical applications,such as the limited development and utilization of environmentally friendly activators,the necessity for a deeper understanding of the structure-performance relationship between HPC and pseudocapacitive materials,and the lack of research on system design.Furthermore,it outlines the fu-ture development directions in the capacitive deionization field,offering valuable insights for researchers aiming to create environmentally friendly,low-carbon,and high-performance CDI electrode materials.
