Conversion of waste biomass to designed and tailored activated chars with valuable properties for adsorption and electrochemical applications.

ABSTRACT: Waste biomass, a renewable energy source, is inexpensive material that has great potential in sorption and electrochemical application. The selected waste materials (corncobs, coconut shells, walnuts, and pistachio husks) allow to close the production cycle and enable material recycling, which are important aspects in the hierarchy of waste management. The proposed methodology for production and activation of biochars can be used industrially due to highly porous structure, developed surface area, and sorption ability of the obtained activated carbons (AC). A significant increase (from 4 up to more than 10 times) in specific surface area (SSA) is observed for all samples after the CO₂ activation process (0.5 h at 800 °C) up to 725 m² g^-1 for corncobs, 534.9
