Abstract:The introduction of carbon nanotubes (CNTs) in the preparation of nano-lead oxide (PbO) can effectively solve the problem of easy agglomeration of nano-lead oxide. This study used concentrated nitric acid and concentrated sulfuric acid mixed acid (volume ratio 1:3) to oxidize carbon nanotubes at 90 °C temperature for 0.5 h. Using and the oxidized CNTs as carriers, Pb(OAc)2 · 3H2O as precursor, concentrated ammonia as a precipitator, PbO/CNTs complexes were prepared by chemical precipitation. Lead content of Pb… Show more
