Reactivity Switch of Platinum with Gallium: From Reverse Water Gas Shift to Methanol Synthesis
The development of efficient catalysts for the hydrogenation
of
CO2 to methanol using āgreenā H2 is foreseen to be a key step to close the carbon cycle. In this
study, we show that small and narrowly distributed alloyed PtGa nanoparticles
supported on silica, prepared via a surface organometallic chemistry
(SOMC) approach, display notable activity for the hydrogenation of
CO2 to methanol, reaching a 7.2 molCH3OH hā1 molPtā1 methanol formation
rate with a 54% intrinsic CH3OH selectivity. This reactivity
sharply contrasts with what is expected for Pt, which favors the reverse
water gas shift reaction, albeit with poor activity (2.6 molCO2 hā1 molPtā1). In situ XAS studies indicate that ca. 50% of
Ga is reduced to Ga0 yielding alloyed PtGa nanoparticles,
while the remaining 50% persist as isolated GaIII sites.
The PtGa catalyst slightly dealloys under CO2 hydrogenation
conditions and displays redox dynamics with PtGaāGaOx interfaces responsible for promoting both the CO2 hydrogenation activity and methanol selectivity. Further
tailoring the catalyst interface by using a carbon support in place
of silica enables to improve the methanol formation rate by a factor
of ā¼5
Rank abundance graphs used to differentiate hotspot and coldspot values from background values.
<p>One linear trend within the background values were characteristic of St Kilda whilst two linear trends were primarily seen at Noarlunga. <b>St Kilda: A</b> VLP 1, microplate 2. <b>B</b> HDNA 1, microplate 2. <b>Noarlunga: C</b> VLP 1, microplate 3. <b>D</b> HDNA 2, microplate 2.</p
Single vertical profile of VLP 1 and LDNA populations at Noarlunga.
<p><b>A</b> Microplate three showing little to no association. <b>B</b> Microplate one showing association. Gap in profile indicates a missing data point.</p
Two-dimensional contour plots showing the highest change in heterogeneity due to the presence of hotspots and coldspots within bacterial and viral subpopulations.
<p>Hotspots and coldspots seen across a distance of 6.3Ć11.3 cm using Surfer 10 (Golden Software, Inc.). Noarlunga: A VLP 2 showing a 2585-fold change in abundance over 0.9 cm. B LDNA showing a 12.9-fold change in abundance over 0.9 cm. St Kilda: C VLP 1 showing a maximum 10.52-fold change in heterogeneity seen over 0.9 cm. D HDNA 2 showing a maximum 45.2-fold change in heterogeneity seen over 0.9 cm. There were a range of heterogeneities over 0.9 cm (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0102805#pone.0102805.s004" target="_blank">Fig. S4</a>) indicating a variety of intensities for hotspots and coldspots. Abundance levels are indicated by a colour intensity scale in units of cells/particles ml<sup>ā1</sup>. Solid red circles indicate areas of abundance higher than the maximum contour level selected. A minimum contour interval value of at least 1000 was chosen based on maximum machine error. The faint gridlines show sample interval.</p
