RESUMO

ABSTRACTBoltorn H30 molecule is the third generation of a commercial polyhydroxylated hyperbranched polymer with an almost globular shape of 3,3 nm average diameter, which has an endo-receptor cavity that can be used for ions or some other small molecules inclusion. In this work, we analyze the spontaneous adsorption of Boltorn H30 on carbon substrates with the aim of generating nanostructured surfaces with the ability to capture or retain copper cations (II) inside. Afterwards, the formed films were taken to an electrochemical cell to reduce the cation and generate metallic structures using the hyperbranched polymer as a template. The platforms developed with electrodeposited copper are useful for the electrocatalysis of hydrogen peroxide. Along this work, the studied surfaces were characterized by means of different spectroscopical, microscopical and electrochemical techniques.
