研究固体表面上催化反应的核磁共振(NMR)方法是近十几年来发展起来的较新的波谱学方法.该法特点是可直接观察在固体表面上反应物与产物浓度的变化,了解吸附分子与表面相互作用力的性质,探测在表面上生成的中间产物,推断反应机理,特别是还可获得吸附分子在固体表面上活动性的动态信息.NMR方法主要用于研究液体样品,对固体样品通常只能获得宽线谱图.但对吸附体系来说,由于物理吸附在本质上类似
A newer spectroscopic method for studying the catalytic reaction on a solid surface is a newer spectroscopy method that has been developed over the last decade. This method is characterized by the direct observation of changes in the concentration of reactants and products on a solid surface, Interaction with the surface of the nature of the probe on the surface of the intermediate products generated to infer the reaction mechanism, in particular, can also be obtained on the adsorption of molecules on the solid surface activity of the dynamic information.NMR method is mainly used to study liquid samples, solid samples Normally, only broad line spectra are obtained, but for adsorption systems, physical adsorption is essentially similar
