We report in situ high-pressure NMR kinetic studies of catalytic oxidations inside heterogeneous catalysts exploiting distortionless enhancement by polarisation transfer (DEPT) ¹³C NMR. ¹H NMR diffusion and relaxation time measurements are then used to elucidate trends in reaction kinetics in different solvents. The work shows the feasibility of non-invasively monitoring intra-particle kinetics, transport and adsorption in porous catalysts using a comprehensive NMR toolkit.

Pd / Al2O3催化剂上苯甲醇氧化的原位高压13C / 1H NMR反应研究

我们报告原位高压核磁共振动力学研究内利用异质催化剂通过极化转移（DEPT）¹³ C NMR的无畸变增强催化氧化。然后使用¹ H NMR扩散和弛豫时间测量来阐明不同溶剂中反应动力学的趋势。这项工作显示了使用全面的NMR工具包以非侵入性方式监测多孔催化剂中颗粒内动力学，转运和吸附的可行性。
