The support used as a substrate for the deposition of catalysts was a commercial aluminumsilicate wool (Lynn Manufacturing, USA) designed to withstand high temperatures. The support was comprised of fibers that were roughly 5-8 μm in diameter as determined by optical microscopy. Sections of the support (1.010g, 60 x 60 x 7 mm) were cut and cleaned using a successive solvent wash of acetone (99%, EMD Millipore Corp), methanol (HPLC grade, VWR Analytical), isopropanol (HPLC grade, VWR Analytical) and water (HPLC grade, VWR Analytical) respectively, all of which were used as received. Once cleaned, the supports were dried at 180 ˚C for 1 hour before a final treatment in a UV-ozone cleaner for 30 minutes. The supports were then used directly for preparing the ALD-synthesized catalysts.
