Surfaces, Volume 6, Issue 2

June 2023 - 6 articles

Cover Story: Biochar, obtained via thermochemical conversion of biomass, offers high porosity and, importantly, various surface functional groups that can be reacted with numerous compounds, e.g. organics, inorganics, and polymers. The cover schematically illustrates numerous procedures to chemically modify the surface of biochar using coupling agents, surfactants, nitrogen-containing molecules, and polymers, as well as nanocatalysts generated in situ during the thermochemical process or immobilized via post-treatment. Surface modification imparts new functionalities to biochar for high-performance applications in agriculture, water treatment, catalysis, CO₂ capture, and EMI shielding, to name but a few potential applications.
