Evaluation of cobalt nanoparticle deposited graphene oxide and carbon nanotube supports as supercapacitor electrodes

Evaluation of cobalt nanoparticle deposited graphene oxide and carbon nanotube supports as supercapacitor electrodes

Cobalt nanoparticles were deposited on multi-wall carbon nanotubes (CNT) and graphene oxide (GO) carbon supports and evaluated as a potential supercapacitor electrodes. The structure and morphology of the cobalt nanoparticles deposited on carbon supports were studied using XRD, TGA, and Raman spectr...

Supercondensador Óxido de Grafeno Nanotubos de Carbono Nanopartículas de Cobalto. Cobalt nanoparticles were deposited on multi-wall carbon nanotubes (CNT) and graphene oxide (GO) carbon supports and evaluated as a potential supercapacitor electrodes. The structure and morphology of the cobalt nanoparticles deposited on carbon supports were studied using XRD, TGA, and Raman spectroscopy. Cyclic voltammetry was used to measure the electrical charge of the electrode based on the materials and their specific capacitance (Csp) were calculated. GO based electrode showed a higher Csp than CNT electrode which is attributed to a larger surface area of the GO carbon support. Interestingly, the deposition of Co nanoparticles promoted an enhanced Csp in the both GO and multi-wall CNT supports. Las nanopartículas de cobalto se depositaron en soportes de carbono, nanotubos de carbono de pared múltiple (CNT) y óxido de grafeno (GO), y se evaluaron como potenciales electrodos de supercondensadores. La estructura y la morfología de las nanopartículas de cobalto depositadas sobre los soportes de carbono se estudiaron mediante XRD, TGA y espectroscopía Raman. La voltametría cíclica se utilizó para medir la carga eléctrica del electrodo en función de los materiales y se calculó su capacitancia específica (Csp). El electrodo basado en GO mostró un Csp mayor que el electrodo CNT, lo cual se atribuye a un área de superficie mayor del soporte de carbono GO. Curiosamente, el depósito de nanopartículas de Co promovió una Csp mejorada en los soportes GO y en los CNT de pared múltiple.
