On the electrooxidation of kraft black liquor on boron-doped diamond

Black liquor (BL) is a highly alkaline byproduct from pulp mills. BL is rich in inorganic and organic compounds, with lignin (a natural polymer) being the most abundant. Following a waste biorefinery concept, the electrolysis of BL comprises lignin oxidation at the anode and hydrogen evolution at the cathode. These paired electrochemical...
