Реферат:
A field-ion microscope (FIM) was used in the investigation of hydrogen oxidation at temperatures between 300 K and 430 K and pressures of p(O-2) = 5.10(-4) mbar, p(H-2) = 3.10(-4) to 7.10(-4) mbar. The H2O molecules produced act as an imaging gas and display the catalytically active surface area. The structure-sensitive H2O formation was studied under steady-state conditions or in the oscillatory regime or in form of chemical waves. The displacement of Pt lattice atoms is spectacular in the Pt(100) plane, where the transformation from (1x1) Pt(100) to hex Pt(100) can be directly imaged.
