Objective
A comprehensive investigation of catalytic surface reaction on an atomic scale will be performed using field ion (FI), field electron (FE), field de-adsorption (FDM) and scanning tunnelling microscopes (STM). A mechanism of surface wave propagation during the catalytic oscillatory reactions (CO + O2, H2 + O2, NO + H2) on surfaces of platinum group metals will be studied with FIM, FEM, FDM, HREELS, LEED, and TDS methods. Corresponding mathematical models for calculation of the reaction rates and for theoretical description of hysteresis and self-oscillation phenomena will be developed. The study of the influence of alkali-caused surface modification on the dynamics of catalytic surface reaction will be performed. A mutual influence of co-absorbed alkali and CO layers will be studied using field ion AE spectroscopy.
A method to create artificially nanometer-size alkali structures on the catalyst surface using new surface diffusion metal ion source in the STM mode will also be developed.
The possibility of influencing catalytic activity on the atomic scale using alkali nanometer-size structures will be studied.
