Wood and Black Liquor-Based N-Doped Activated Carbon for Energy Application

Fuel cells, batteries and supercapacitors are critical to meet the rising global demand for clean, sustainable energy. Biomass-derived activated carbon can be obtained with tailored properties fulfil extensive need low-cost, high-performance, catalyst electrode materials. To investigate possibility of nanoporous nitrogen-doped materials as catalysts in fuel cells electrodes lithium-ion batteries, biomass precursors were thermochemically NaOH at 800 °C, nitrogen was introduced using dicyandiamide doping performed °C. The chemical composition, porous structure, texture electrochemical change depending on precursor used. It has been found that most promising is wood char, both an oxygen reduction which shows better than commercial 20% Pt/C catalyst, anode material Li-ion batteries. However, based black liquor hybrid have comparable considered a cheaper alternative.
