The uniformity, flexibility and resistance to bending of these films make them one of the most interesting membranes in a wide range of applications. CNT electrodes were characterized by Raman spectroscopy and scanning electron microscopy and their electrochemical performance was assessed employing various redox species such as ferrocenemethanol, hexacyanoferrate (II) and dopamine. Free-standing single-walled CNT electrodes exhibit good conductivity and transparency to UV–vis radiation, making them suitable as optically transparent electrodes. This is exemplified by monitoring, using UV–vis absorption spectroelectrochemistry, the electrodeposition of gold nanoparticles (AuNPs) on one face of the free-standing CNT electrodes, while the other face remained unmodified PB Elsevier SN 1388-2481 YR 2016 FD 2016-11 LK http://hdl.handle.net/10259/4940 UL http://hdl.handle.net/10259/4940 LA eng NO Ministerio de Economía y Competitividad (CTQ2014-55583-R, CTQ2014-61914-EXP, CTQ2015-71955-REDT) and Junta de Castilla y León (BU033U16) DS Repositorio Institucional de la Universidad de Burgos RD 28-mar-2024
