The approach comprises deposition-precipitation (DP) of Au(OH)3 onto the hydroxide surfaces of metal oxide supports from an alkaline solution of HAUCI4 [26] and grafting of organo gold complexes such as dimethyl gold (Ill)acetylacetonate (hereafter denoted as Au acac complex) [27] and Au(PPh3)(N03) [28] either in gas and liquid phase are advantageous in that a variety of metal oxides commercially available in the forms of powder, sphere, honeycomb can be used as supports. [Pg.184]

In the grafting method, a gold complex in solution reacts with the surface of a support, forming species convertible to a catalytically active form. Thus, the compounds [Au(PPh3)]N03 and [Au9(PPh3) ](N03)3 have been grafted onto the surface for a number of freshly precipitated wet hydroxides [18,68-73]. [Pg.384]

MgO-supported mono-nuclear gold complex catalysts have been evaluated for ethene (or ethylene) hydrogenation at 353K [464]. The results provided evidence of the stability of the metal complex, complex-support interactions... [Pg.430]

Platinum has been deposited onto single-walled nanotubes by reduction of K2PtCl4 by ethylene glycol at 393 to 403 K [66]. Gold deposition onto carbon supports has been realized using an aqueous chloride-stabilized gold complex... [Pg.169]
