Abstract

Biochar derived from rich biomass has been considered as a sustainable alternative in the development of electrochemical devices for environmental remediation because of its good electroactivity, cheapness, and eco-friendliness. In this review, we investigated the electrochemical applications of biochar in water purification and soil remediation. The electrochemical properties of biochar depend on the preparation conditions, including feedstock, pyrolysis temperature, and crushing and sieving. Multiple modification methods can be applied to improve its characteristics of specific surface area, pore structure, conductivity, heteroatom active sites, and surface functional groups. Furthermore, it has been widely used as an electrode material or electrode modifier in water/wastewater treatment and desalination. The common water purification devices include electrochemical advanced oxidation process, microbial fuel cell, microbial electrolysis cell, three-dimensional biofilm electrode reactor, and capacitive deionization. Biochar exhibits a great potential in soil electrochemical remediation as an electrode material or transmission medium of soil microbial fuel cell. Finally, we summarized the technical challenges of biochar in practical applications and discussed the possible development directions of biochar-based electrochemical remediation technology.

期刊介绍： The Chemical Engineering Journal is an international research journal that invites contributions of original and novel fundamental research. It aims to provide an international platform for presenting original fundamental research, interpretative reviews, and discussions on new developments in chemical engineering. The journal welcomes papers that describe novel theory and its practical application, as well as those that demonstrate the transfer of techniques from other disciplines. It also welcomes reports on carefully conducted experimental work that is soundly interpreted. The main focus of the journal is on original and rigorous research results that have broad significance. The Catalysis section within the Chemical Engineering Journal focuses specifically on Experimental and Theoretical studies in the fields of heterogeneous catalysis, molecular catalysis, and biocatalysis. These studies have industrial impact on various sectors such as chemicals, energy, materials, foods, healthcare, and environmental protection.
