manufacture Embodiment 1
[0133] The HF alumina material InnoCep-N-800 supplied by HyFlux CEPAparation Technologies Europe was used and the Ni carbon growth catalyst was introduced using the following process steps:
[0134] Hollow alumina fibers without any previous treatment were immersed in Ni nitrate solution (0.5mg / 80ml). The Ni nitrate solution was adjusted to pH = 3.5 using dilute nitric acid (concentration 1%). To precipitate Ni onto the alumina, 20ml of concentrated urea solution (1.06g / 20ml) was added dropwise to initiate the precipitation of Ni. The temperature was then adjusted to 100°C and maintained at 100°C to achieve the decomposition of urea. After a deposition time of 2 hours, the sample was rinsed according to ISO 3696 with type 1 ultrapure water (Milli Q water supplied by Millipore Corporation) and dried under vacuum at 80° C. for 2 hours.
[0135] CNFs were then introduced into the catalyst element by flushing the catalyst element with ethylene gas at a temperature of about 600°C...
manufacture Embodiment 2
[0142] Catalyst Element Production Example 2 was the same as Catalyst Element Production Example 1 except for the following. In this example, the noble metal precursor palladium acetylacetonate (6 mg / ml) was used. The deposition time was 17 hours in toluene. After impregnation the catalyst element was vacuum dried at 80°C for 2 hours. Then pass as Example 1 The dip coating method used in coats a layer of PDMS with a thickness between 5 and 150 μm on the first surface to produce a catalyst element impregnated with noble metals.
manufacture Embodiment 3
[0144] The catalyst element obtained by Catalyst Element Production Example 1 was modified by adding Cu to the noble metal-containing material to form a bimetallic catalyst. Copper is introduced using a reduction step, however other alternative methods of introducing copper or other non-noble metals will be apparent to the skilled person. The catalyst element with Pd noble metal material was immersed in an aqueous solution containing copper nitrate salt. Make H 2 Bubble through this aqueous solution for 24 hours (although other reducing agents known to the skilled person can be used, such as formic acid). Copper is reduced at the surface of Pd, creating a good contact between the two metals (Pd and Cu). The catalyst element was then dried at 80°C for 2 hours, calcined and reduced, and then passed through as Example 1 The dip coating method used in coated a PDMS layer with a thickness between 5 and 150 μm on the first surface to obtain modified catalyst elements.
