Fabrication of CuO nanoparticle interlinked microsphere cages by solution method

<p>Abstract</p><p>Here we report a very simple method to convert conventional CuO powders to nanoparticle interlinked microsphere cages by solution method. CuO is dissolved into aqueous ammonia, and the solution is diluted by alcohol and dip coating onto a glass substrate. Drying a...
