“…20,21 Recent studies have demonstrated the feasibility of using bio-based IHPCs for the removal of heavy metals 22 and organic pollutants, 23 carbon capture, 24 and enhancing anaerobic digestion (AD) processes, 25 antimicrobial treatment, 5 and oil-water separation. 26 Bio-based IHPCs have also been used for desalination or water soening based on the electrosorption mechanism, 27,28 supercapacitors and the hydrogen evolution reaction. [29][30][31] However, the majority of previous review papers focused solely on the role of hierarchical porous structures in traditional HPC without chemical doping.…”
