Influência da fonte de carbono nas propriedades de híbridos Ni/Carbono preparados por carbonização hidrotérmica e tratamento térmico e utilizados como suportes para eletrocatalisadores PtRu/C

Abstract: RESUMO Neste trabalho, híbridos Ni/Carbono foram preparados em duas etapas (carbonização hidrotérmica e tratamento térmico a 900 °C sob argônio) a partir de diferentes fontes de carbono: glicose, amido e celulose. Eletrocatalisadores PtRu/C foram preparados pelo método da redução por álcool utilizando os híbridos como suportes. Os materiais foram caracterizados por espectroscopia por energia dispersiva de raios-X (EDX), análise termogravimétrica (TGA), espectroscopia no infravermelho com transformada de Fourie… Show more

“…In the DTG curve, it is possible to see the degradation peak corresponding to this process, which can be assigned to some residual organic material from the synthesis. [175][176][177] The main weight loss occurs between 400 and 650°C due to the carbon decomposition. [177] For each material, the curves reach stability in The results shows that the more PtCl6 2 we added, more intense are the peaks corresponding to AgCl, Pt and PtO.…”
