Hydrogen as an energy vector in combination with fuel cells is one of the emerging energy solution in terms of sustainability and low environmental impact. H2 sustainable production is therefore one of the key target of today. Recently, the Materials, Environment and Energy research group at the University of Trieste, coordinated by Professor Paolo Fornasiero investigated various options for H2 production and purification by using a Hiden HPR 20 quadrupole mass spectrometer.

The mass spectrometer was used to prove the superior thermal stability, during methane partial oxidation Figure 1, of an innovative embedded Rh@Al2O3 catalyst with respect to conventional impregnated material (1).

More recently, the same research group used the mass spectrometer to investigate methanol steam reforming and Water Gas Shift Reactions over an embedded Pd@CeO2 (2) and the Preferential Oxidation Reaction over an embedded Au@CeO2 catalyst under (3). Furthermore, it was used to characterize an embedded Ru@ZrO2 based catalyst during ammonia decomposition reaction (4). Finally, the Hiden HPR 20 quadrupole mass spectrometer was determinant to evaluate the amount and nature of coke deposited during ethanol steam reforming on Cu/ZnO/Al2O3 based catalysts (5).
