Data for: High surface area perovskite materials as functional catalyst supports for glycerol oxidation

A series lanthanum perovskite supports (LaBO₃, where B = Cr, Mn, Fe, Co and Ni) were synthesised using a hard templating methodology with a mesoporous silica template (SBA-15). This methodology produced high surface area perovskites with surface areas of 70-160 m² g^-1. 1 wt% AuPt was added to the perovskite supports using sol immobilisation and the resultant catalysts tested for the oxidation of glycerol. When the AuPt/LaBO₃ catalysts were tested for glycerol oxidation the product distributions via either the oxidation mechanism or a dehydration mechanism could be tuned by substituting different transition metals in the B site. In line with previous studies, AuPt/LaMnO₃ and AuPt/LaCoO₃ gave the highest yield of oxidation products (glyceric acid with small amounts of tartronic acid), AuPt/LaCrO₃ gave the highest yield of lactic acid through the dehydration pathway, while AuPt/LaNiO₃ and AuPt/LaFeO₃ gave a mixture of products from both the oxidation and dehydration pathways. The product distributions were found to change over the course of the reaction due to the relative rates of the two reaction pathways. For all catalysts except AuPt/LaMnO₃ the yield of oxidation products stopped after two hours, while all catalysts except AuPt/LaMnO₃ continued to produce lactic acid over the whole reaction. This suggests the porovskite supported catalysts are not stable over the course of the reaction. The most interesting behaviour was found for the AuPt/LaFeO₃ catalyst that gave a high initial selectivity to tartronic acid, although further studies are needed to elucidate the mechanism fully.The data file contains X-ray diffraction data, thermal gravimetric analysis and ammonia temperature programmed desorption data for the perovskite supports, and electron microscopy and catalyst testing data for the AuPt/LaBO₃ catalysts.X-ray diffraction data is given as intensity versus 2 theta in degrees for the perovskites supports: LaCrO₃, LaMnO₃, LaFeO₃, LaCoO₃, LaNiO₃.For the catalyst testing: Conversion of glycerol is given as a percentage<br>For the catalyst testing: <br>Conversion of glycerol is given as a percentageSelectivity to products is given as a percentageCarbon mass balance is given as a percentage of the total moles of carbon before the reaction/total carbon after reaction x 100The amount of the products formed is given in mmolProduct abbreviations used are: <br>GA = Glyceric acid<br>TA = Tartronic acid<br>LA = Lactic acid<br>C-C scission = C1 and C2 products<br>Reaction conditions: glycerol (0.3 M), NaOH: substrate ratio (4:1), O2 (3 bar), substrate:metal ratio =1000, 100 ◦C.
