The importance of cooperation of heterogeneous catalysis with surface science is stressed for simultaneous adsorptive and catalytic measurements. Inverse gas chromatography and reversed-flow gas chromatography offer a suitable research ground for such collaboration. After a short introduction, adsorption physicochemical quantities of heterogeneous catalysts with typical recent results, chemical kinetic properties and surface energy of catalysts are described, stressing the important aspect of time-resolved chromatography, due to the heterogeneity of the solid surface of catalysts. Adsorption energies, local monolayer capacities, local isotherms and energy distribution functions are extensively described. Also, lateral molecular interactions, surface diffusion and adsorption rates on heterogeneous catalysts are described.
强调了多相催化与表面科学合作对于同时进行吸附和催化测量的重要性。反相气相色谱法和反向流动气相色谱法为此类合作提供了合适的研究基础。在简短介绍之后，描述了具有典型近期结果的多相催化剂的吸附物理化学量、催化剂的化学动力学性质和表面能，强调了由于催化剂固体表面的不均匀性而导致的时间分辨色谱法的重要方面。广泛描述了吸附能、局部单层容量、局部等温线和能量分布函数。此外，还描述了多相催化剂上的横向分子相互作用、表面扩散和吸附速率。
