Biochar for electrochemical applications

Carbon-rich biochar can be produced by pyrolysis of biomass. Depending on the precise production pathway, the surface chemistry and porosity can be tuned and made compatible for a defined application. This shear benefit has persuaded researcher to explore its suitability in various electrochemical applications related to energy storage and conversion. In this article, we succinctly discuss the potentials of biochar in electrocatalysis, fuel cell, supercapacitors, and rechargeable batteries. We have concluded this article with recommendations for future research.
