This product consists of gold nanoparticles (AuNPs) anchored on TiO₂ powder. The TiO₂ (anatase) powder is derived from ground and sieved NorPro® ST31119 TiO₂ pellets. The NorPro® ST31119 TiO₂ material is a commercial catalyst support from Saint Gobain NorPro with mean pore diameters (MPDs) of 38 nm and a specific surface area (SSA) of 40.7 m²/g.
Our catalyst material is an egg-shell catalyst with AuNPs 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 AuNPs can be chosen independently. The AuNPs feature narrow size distributions with polydispersities of about 20 %. Please choose your desired AuNP 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 AuNPs can slightly differ between batches but we guarantee the mean size within ± 0.5 nm. 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.
