Aqueous synthesis of porous platinum nanotubes at room temperature and their intrinsic peroxidase-like activity

Platinum nanotubes (PtNTs) exhibiting high porosity were constructed by sacrificing the exterior of tellurium nanowires (TeNWs) and disintegrating the inner part spontaneously in aqueous solution at room temperature, in which the Kirkendall effectmay play an important role. The present PtNTs exhibited intrinsic peroxidase- like activity in the presence of H2O2.
