The size of Pt particles introduced into the channels of ZSM-5 zeolite by two different preparation methods has been studied with EXAFS. ZSM-5 was loaded with 2 wt 5% Pt by ion exchange and by impregnation. By careful calcination of the catalysts the

Desorption of hydrogen at high temperature leads to a contraction of the Ir–Ir coordination distance of highly dispersed iridium metal particles. The long metal–support oxygen distance (2.55 A) observed if the metal crystallites are covered with

The possibility of direct selective surface activation by photodeposition of autocatalytic Cu particles on photosensitiveTiO2 substrates in an alkaline electroless copper solution has been investigated. The nucleation and growth of particleswere char

In order to be independent of poor availability of synchrotron beamtime a laboratory EXAFS spectrometer has been developed. The X-ray source is a rotating anode generator (max. voltage 60 kV, max. current 300 mA). Monochromatisation and focusing is d
