摘要

摘要综述了(皮秒)非线性红外光谱在沸石催化剂和吸附剂研究中的应用。在这些时间分辨实验中,沸石系统中的一个特定振动(即沸石或吸附质振动)被选择性地用超短(可调谐)中红外脉冲激发。这种激发和随后的能量松弛的影响可以实时监测,提供裸沸石和吸附配合物的结构信息。更重要的是,通过这项技术,可以研究催化部位的皮秒能量流和催化剂-吸附物相互作用的动力学:观察到短暂的瞬态物质(例如,反应中间体),并且在催化部位的皮秒弛缓速率和途径可以在分子水平上深入了解沸石催化剂与其吸附物之间相互作用的动力学。这说明了时间分辨红外光谱在工业领域的潜力。

Dynamical studies of zeolitic protons and adsorbates by picosecond infrared spectroscopy
Abstract The application of (picosecond) nonlinear infrared spectroscopy to investigate zeolite catalysts and adsorbates is reviewed. In these time-resolved experiments, one specific vibration in the zeolite system (i.e., a zeolite or adsorbate vibration) is selectively excited with an ultrashort (tunable) mid-infrared pulse. The effect of this excitation and the subsequent energy relaxation can be monitored real time, providing information on the structure of the bare zeolite and adsorption complexes. More importantly, with this technique the picosecond energy flow at the catalytic site and the dynamics of the catalyst-adsorbate interaction can be investigated: Short-lived transient species (e.g., reaction intermediates) are observed and the picosecond relaxation rates and pathways at the catalytic site render insights into the dynamics of the interaction between the zeolite catalyst and its adsorbates at a molecular level. This illustrates the potential of time-resolved infrared spectroscopy in the inve...
