In spite of the relatively low specific surface areas presented, the catalysts achieved significant ethanol conversion values at the beginning of the test.
As shown in Fig. 3, all the catalysts present the diffraction peaks at 31.2, 36.8, 44.8, 59.4 and 65.3°, suggesting that the catalysts contain the face-centered cubic spinel of crystalline Co3O4.
Thus sulfur groups present on the catalyst surface form the key components for the reactions.
The specific nature of the gallium species present on the catalyst was investigated by collecting Ga MAS NMR (magic-angle spinning NMR) and XPS (X-ray photoelectron spectroscopy) spectra of the fresh Pt3Ga and 3Ga catalysts.
From Fig. 22c one can conclude that zeolite Y is a randomly distributed, although the embedded zeolite material is not entirely homogeneously present in the catalyst matrix, and some hot spots of high amounts of zeolite Y are found.
It presented the highest catalyst activity and electrochemical active surface area value as 274.72 mand−1 and 226.75m2 g−1 PtRu, respectively, compared with the other samples.
Presented by the Catalyst Collaborative@MIT, the science theater collaboration betweenUnderground Railway Theater (URT) and MIT.
Analytical solutions are presented for the catalyst distribution that results when the impregnated catalyst is dried rapidly immediately after soaking.
This study presents the effects of catalyst loading, temperature, and electrolyte concentration.
The non-annealed catalyst (ZNST) and the annealed catalyst (ZNT) presented the highest and the lowest catalyst activity, respectively.
