Catalytic Properties of Ni3Al Foils for Methanol Decomposition

“…Native Ni oxide may form, but probably it is too thin to be detected. After 1 h, the Al met and AlO x peaks disappeared and were replaced by a peak at higher binding energies corresponding to those of Al 2 O 3 and/or Al(OH) 3 . The corresponding O 1s spectra (figure 4b) can be well fitted by two components at binding energies of 532.7 and 533.9 eV, which correspond to the binding energies of Al 2 O 3 and Al(OH) 3 , respectively [22].…”

“…We have overcome this problem by directional solidification [11,12] and have succeeded in cold-rolling this compound into thin foils 23 lm in thickness [13]. Recently, we also found that intermetallic compound Ni 3 Al powder showed high catalytic activity and selectivity for methanol decomposition (CH 3 OH fi 2H 2 + CO) after alkali-leaching treatment [14,15]. These results suggest a possibility of the Ni 3 Al foils to be used both as catalysts and as structural sheets in the microreactors.…”

“…Ni 3 Al is known as a high-temperature structural material because of its excellent high-temperature strength and oxidation/corrosion resistance [10]. Its brittleness at ambient conditions, as with many other intermetallic compounds, used to be a serious problem.…”

“…Efficient and low-cost hydrogen production from alcohol or hydrocarbon is an important part of fuel cell technologies [1][2][3][4]. A microreactor is a promising device for this process because of a high surface-to-volume ratio and high rates of heat and mass transfer compared with conventional reactors [5,6].…”

Low Temperature and H2 Selective Catalysts for Ethanol Steam Reforming

“…Commercially, hydrogen has been produced from catalytic steam reforming of fossil fuels, for example, methane [1]. To reduce greenhouse gas emissions, hydrogen should be derived from renewable energy sources such as bioethanol [2][3][4]. As a consequence, ethanol steam reforming has been studied, as it provides an alternative fuel source for hydrogen production [4][5][6].…”
