在这篇手稿中，钌（Ru）纳米粒子功能化与氮烯配体通过钌-氮烯（Ru双键N）π键进行了探索。通过合成氮烯配体，用15 N标记和未标记的氮烯配体，用实验和理论计算的FTIR光谱证实了Ru纳米粒子上存在Ru双键N π键。通过吸附13 CO的Ru纳米粒子的魔角旋转固体碳核磁共振谱（13 C NMR）、光致发光和苯乙烯加氢反应，进一步表征了氮烯配体在Ru纳米粒子表面的配位、界面电荷离域以及氮烯配体对Ru纳米粒子催化性能的影响。
In this manuscript, ruthenium (Ru) nanoparticles functionalized with nitrene ligands through the ruthenium-nitrene (Rudouble bondN) π bonds are explored. By synthesizing the nitrene ligands with and without15N-labelling, Rudouble bondN π bonds on Ru nanoparticles are evidenced by experimental and theoretically calculated FTIR spectra. The coordination of nitrene ligands on Ru nanoparticles surface, the interfacial charge delocalization and the impact of nitrene ligands on the catalytic performance of Ru nanoparticles are further characterized by magic-angle spinning solid-state carbon nuclear magnetic resonance spectroscopy (13C NMR) of13CO-adsorbed Ru nanoparticles, photoluminescence and the hydrogenation of styrene.
