This product consists of palladium nanoparticles (PdNPs) anchored on α-Al₂O₃ powder. The α-Al₂O₃ powder is derived from ground and sieved NorPro® SA5102 Al₂O₃ pellets. The NorPro® SA5102 Al₂O₃ material is a commercial catalyst support from Saint Gobain NorPro with mean pore diameters (MPDs) of 1.2 µm and a specific surface area (SSA) of 1 m²/g.
Our catalyst material is an egg-shell catalyst with PdNPs in the outer shell of the support. This outer shell has a thickness of less than 2 µm. The size of the support material (from each sieved fraction) and of the PdNPs can be chosen independently. The PdNPs feature narrow size distributions with polydispersities of about 30 %. Please choose your desired PdNP size, metal loading and sieve fraction of the support material (see drop down menu for options). Every catalyst material is custom made and therefore the mean size of the PdNPs can slightly differ between batches but we guarantee the mean size within ± 0.5 nm for the small nanoparticles and ± 1 nm for the larger. Choose the optional TEM analysis to receive images as well as the size distribution for your catalyst material. In addition to the numerous offered combinations we also provide materials made according to your specifications. Please contact us for a quote or any further information.
