Platinum Nanoparticles Loaded on Ta2O5/MWCNTs to Improve Methanol Electrooxidation Activity
The composite materials of Pt-based catalysts and metal oxides have potential advantages in direct methanol fuel cells. However, synthesizing controllable Pt-based catalysts with high electrochemical properties is still challenging. In this paper, commercial Pt/C is improved by replacing commercial carbon black with carbon nanotubes and adding Ta2O5 cocatalyst. The particle size, structure, surface morphology, activity, and stability of the methanol oxidation reaction (MOR) of Pt/Ta2O5/MWCNTs composites were studied. The prepared Pt/Ta2O5/MWCNTs catalysts have higher catalytic activity and durability than commercial Pt/C in methanol electrooxidation reactions. In addition, when the loading of co-catalyst and Pt nanoparticles is adjusted, the catalyst with the loading of 20% Pt/MWCNTs/Ta2O5-15% has better electrochemical activity. This study shows that the Pt/ Ta2O5/MWCNTs catalyst should be a promising DMFC catalyst.
期刊介绍：
Catalysis Letters aim is the rapid publication of outstanding and high-impact original research articles in catalysis. The scope of the journal covers a broad range of topics in all fields of both applied and theoretical catalysis, including heterogeneous, homogeneous and biocatalysis.
The high-quality original research articles published in Catalysis Letters are subject to rigorous peer review. Accepted papers are published online first and subsequently in print issues. All contributions must include a graphical abstract. Manuscripts should be written in English and the responsibility lies with the authors to ensure that they are grammatically and linguistically correct. Authors for whom English is not the working language are encouraged to consider using a professional language-editing service before submitting their manuscripts.
