For instance, studies have shown that nickel oxide (NiO) nanoparticles can be effectively decorated onto carbon nanotubes (CNTs) using a pulsed laser ablation method. This NiO-CNTs nanocomposite ...

13.373) Top-down approaches involve the breakdown of bulk materials into smaller nanoparticles. Examples include mechanical milling, laser ablation, and lithography ... can be used for photocatalytic ...
