In this study, we report the cost-effective and simple synthesis of carbon-coated α-MnO2nanoparticles(α-MnO2@C) for use as cathodes of aqueous zinc-ion batterie
Galvanic deposition method was used to prepare the Pd/Ni-Al2O3-GD catalyst for the combustion of methane under lean conditions. The new catalyst and compared ca
Nano-sized γ-alumina (γ-Al2O3) was first prepared by a precipitation method. Then, active component of cobalt and a series of alkaline- earth metal promoters
