Thermal characterisation of molybdenum and platinum-molybdenum catalysts
Abstract Alumina supported Mo and Pt-Mo catalysts was subject to temperature programmed reduction (TPR) using $ H_{2} $ and CO. After earlier oxidation step TPR–$ H_{2} $ profiles shows different surface species, which depends on the composition of the catalysts and reduction temperature. Change in...

Thermal characterisation of molybdenum and platinum-molybdenum catalysts |
| abstract |
Abstract Alumina supported Mo and Pt-Mo catalysts was subject to temperature programmed reduction (TPR) using $ H_{2} $ and CO. After earlier oxidation step TPR–$ H_{2} $ profiles shows different surface species, which depends on the composition of the catalysts and reduction temperature. Change in reducing gas from $ H_{2} $ into CO results in significant changes in catalyst system. Hydrogen causes a decrease in oxidation number of metals, while carbon monoxide reacts with chemisorbed chemicals. © Springer-Verlag 2007 |

After earlier oxidation step TPR–$ H_{2} $ profiles shows different surface species, which depends on the composition of the catalysts and reduction temperature. Change in reducing gas from $ H_{2} $ into CO results in significant changes in catalyst system. Hydrogen causes a decrease in oxidation number of metals, while carbon monoxide reacts with chemisorbed chemicals.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Mo/Al</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">O</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Pt-Mo/Al</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">O</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">catalysts</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">TPR–CO</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">TPR–H</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Jóźwiak, W.
