Biochar from Spent Malt Rootlets and Its Application to an Energy Conversion and Storage Device

Activated carbon obtained from biomass wastes was presently studied in order to evaluate its applicability an energy storage device. Biochar by the carbonization of spent malt rootlets and further processed mild treatment NaOH. The final product had a specific surface 362 m2 g−1 carried Na, P few mineral sites. This material first characterized several techniques. Then it used make supercapacitor electrode, which reached capacitance 156 F g−1. electrode combined with photocatalytic fuel cell, making simple three-electrode device functioning single alkaline electrolyte. allows solar conversion at same time, promoting use for applications.
