High throughput methods have been developed for study of the properties of CuxPd1-x and CuxAuyPd1-x-y alloys used in hydrogen purification membranes and as hydrogenation catalysts. These alloys have been deposited on Mo substrates as Composition Spread Alloy Films to form high throughput libraries that span all of composition space, x = 0 ? 1 and y = 0 ? 1-x. Using a high throughput microreactor we have measured the kinetics of catalytic H2 dissociation via H2-D2 exchange and the kinetics for ethylene hydrogenation across all of binary and ternary alloy space. Analysis of the CuxPd1-x alloys using UPS has allowed measurement of the position of the d-band center at all compositions and correlation of the barriers to hydrogen adsorption and desorption with the position of the d-band. XPS has been used to map out the regions of the composition space over which the alloy exists in fcc versus bcc structures.
