Structure and dynamics of carbon dangling bonds in activated carbon materials from biomass†
Abstract: Activated carbon materials are inevitable for energy-related applications. Production of such materials from biomass is sustainable. Microporous activated carbon materials with high specific surface area and pore sizes of less than 2 nm find life-saving applications apart from their utility in environmental remediation. The free electron density of these materials is tunable and is a measure of electrical conductivity that is useful for the development of green and renewable energy …
