Biochar has emerged as a new class of biomass-derived functional materials that can be obtained using plethora thermochemical conversion techniques. Biochar-based environmental catalysts have potential applications toward positive, planet-level impact. Here, recent observations in the activated conversions emerging contaminants are reviewed, highlighting most influential advancements, including metal-free processes. The status quo underlying interaction mechanisms summarized, revealing active moieties, persistent free radicals, graphitic degree and electron transfer capacity collectively synergistically regulate catalytic potency. These remarkable features convey biochar's high activity flexibility into viable chemo-redox, photo-, bio-, sono-, electrocatalysis. Advanced coupling processes some perspectives on future possibilities proposed at end.

Biochars are used globally in agricultural crop production and environmental remediation. However, environmentally persistent free radicals (EPFRs), which stable emerging pollutants, generated as a characteristic feature during biomass pyrolysis. EPFRs can induce the formation of reactive oxygen species, poses huge agro-environmental human health risks. Their half-lives persistence both biochar residues atmosphere may lead to potentially adverse risks environment. This review highlights comprehensive research into these bioreactive radicals, well bottlenecks leading up EPFRs. Additionally, way forward has been proposed, based on two main recommendations. A global joint initiative create an all-encompassing regulations policy document that will improve technological quality control aspects biochars reduce EPFR generation at level. Furthermore, impact risk assessment studies should be conducted extensive applications order protect health. The highlighted key directions proposed herein shape production, research, adoption biochars, mitigate considerable concerns raised
