Ru Supported on p‐phthalic acid‐Mn Derived from a Mn Metal–Organic Framework for Thermo‐ and Electrocatalytic Synthesis of Ethylene‐D4 Glycol

Deuterium-labeled polyols are one of the most extensive applied chemicals in biochemistry and biophysics. However, the deuteriation still is insufficient, exhibiting a low deuterated ratio and indistinct reaction mechanism. Herein, Ru supported on MnBCD (MnBDC, derived from Mn p-phthalic acid metal-organic framework) as nanocatalyst with an agglomerated sheet-type structure; this allows the possibility of achieving both thermo- and electrocatalytic hydrogen isotope exchange (HIE) reaction. Furthermore, XPS characterization confirmed that the specific structural changes in the electron density of Ru outer layers were modulated through the impregnation and reduction processes. According to the change of outer electronic structure, hydrogen spillover and electron-rich flow promote the reaction of the catalyst in thermo- and electrocatalytic systems, respectively. In addition, the results indicate that a high deuterated ratio of 97 % can be obtained, hence the catalytic technology has enormous potential for the synthesis of a broad variety of deuterium-labeled compounds.
