The rational development of heterogeneous catalysts is a prerequisite for improving current catalytic technologies. One of the most successful approaches to achieve this goal is the grafting of organometallic complexes onto a given support, via surface organometallic chemistry (SOMC). In such cases, the immobilization of (transition) metal centres onto an inorganic support affords single-site catalysts with precise tuning of the coordination sphere and thus target-specific catalytic reactivity. In this context, the precise characterization of the surface sites by several spectroscopic techniques in parallel is of paramount importance. Solid-state NMR, in particular for half-integer quadrupolar nuclei, is a method that has increased its scope in the field of catalysis, especially due to recent methodological breakthroughs, occasionally combined with DFT calculations. In this tutorial review, we provide an overview of the most robust and efficient NMR experiments for half-integer quadrupolar nuclei, from simple one-dimensional acquisition under static and MAS conditions up to high-resolution and heteronuclear correlation two-dimensional spectra, as illustrated by selected examples.

用于研究负载型有机金属催化剂的四极核的固态NMR：范围和前沿

合理开发多相催化剂是改进现有催化技术的前提。实现此目标的最成功方法之一是通过以下方法将有机金属配合物嫁接到给定的载体上表面有机金属化学（SOMC）。在这种情况下，将（过渡）金属中心固定在无机载体上可提供具有精确调节配位范围并因此具有目标特异性催化反应性的单中心催化剂。在这种情况下，通过几种并行的光谱技术精确表征表面位点至关重要。固态NMR，特别是对于半整数四极核而言，是一种在催化领域中扩大了应用范围的方法，特别是由于最近的方法学突破，偶尔与DFT计算结合使用。在本教程的评论中，我们概述了半整数四极核的最健壮和高效的NMR实验，
