“…biofuels such as biohydrogen, bioethanol, and biodiesel. 20,[24][25][26][27][28][29] Biomass or biomass residues can undergo chemical transformations where they are turned into solid materials with high added value that can be applied in energy storage devices, such as supercapacitors and batteries. [30][31][32] These biomass *value-added materials, from an environmental and sustainable point of view, can be applied as carbon-based adsorbents (activated carbon, biochar, magnetic biochar, and mesoporous carbon) in the capture of gases such as CO 2 and methane and in the treatment of wastewater.…”
