Abstract:
A citric acid and sodium citrate buffer solution based lead acid battery paste recycling process has been advanced by our group. It was found that the intermediate recycling products, lead citrate, could be used as precursors to produce hierarchical porous carbon monoliths and lead/carbon composites. Lead/carbon composite with nanosized lead particles anchored on porous carbon monolith could be produced by paralyzing of lead citrate precursors under Ar atmosphere at various temperatures. The size of lead particles was controlled by applying different pyrolysis procedures. By coating lead citrate precursors with PVP gel, the size of lead particles reached to as low as several nanometers. The lead particles inside the lead/carbon composite can be used to produce other lead containing compounds like PbS, PbI and PbO for energy materials application by taking advantage of the high activity of its nanosize. In addition, by washing away the nanosized lead particles, porous carbon materials with high specific surface area and hierarchical porous nanostructure was produced. The as prepared carbon materials can also be used as energy materials in new energy storage systems.
