Formation and migration of carbon produced in the dissociation of CO on Rh/TiO2(110)-(1 x 2) model catalyst: a scanning tunneling microscopy study

Article Abstract:

An analysis of the formation and thermal-induced migration of carbon nanoclusters produced by the decomposition of CO on Rh/TiO2(110)-(1 x 2) planar catalyst is presented. Adsorption of CO on a Rh-free TiO2(110)-(1 x 2) surface prompted transformation of the (1 x 2) surface structure into the (1 x 4) arrangement at 500 K.

Effects of different gases on the morphology of Ir nanoparticles supported on the TiO29110)-(1 x 2) surface

Article Abstract:

The preparation of Ir nanoparticles supported on the TiO2(110)-(1 x 2) surface and the effects of annealing in different gases by scanning tunneling microscopy are studied. Annealing of Ir-covered surfaces is seen to cause only slight changes below 700K but has led to migration and coalescence of the particles above 700K.

Encapsulation of Rh nanoparticles supported on TiO2(110)-(1 x 1) surface: XPS and STM studies

Article Abstract:

X-ray photoelectron spectroscopy and scanning tunneling microscopy (STM) were used to investigate the encapsulation of Rh nanoparticles supported on a TiO2(110) surface. No indication for a thermally induced decoration of the metal particles by the suboxide phase of titania in the temperature range 300-800 K in ultrahigh vacuum was seen for a stoichiometric and well-ordered TiO2(110) surface. However, a few minutes of annealing on a H2 atmosphere of 10(super -4) mbar at 750K can induce encapsulation. STM imaging clearly showed decoration islands on top of the coin-shaped Rh particles. During the encapsulation process induced by thermal treatment in H2 ambient, the specially grown giant Rh crystallites decompose into smaller particles.
