Abstract Transition metal‐catalyzed transfer hydrogenation (TH) with in situ negative hydrogen (H − ) has received extensive attention as an alternative to conventional high‐pressure processes. However, the insufficient activity of production and unclear conversion process remain a great challenge. In this work, brand new bimetallic ternary‐structured catalysts (Ru 1+n M 1 ‐TiO 2 , M=Co, Cu, Fe, Ni) were synthesized efficiently generate H donors from ammonia borane (AB, NH 3 BH for nitrobenzene under moderate conditions. The Ru Co exhibited highest form AB hydrolysis TOF value 2716 min −1 . achieved >90 % yields within 3–4 hours converting anilines using AB. Mechanistic studies revealed that high was due SA sites bimetallic‐ternary‐structured catalyst required lowest energy activation O, respectively. Remarkably, clusters obvious synergistic effect TH process, which promoted tandem nitroaromatics. This work demonstrated efficient approach donor further provided inspiration on development multifunctional catalysts.

Magnesium hydride (MgH2) has been recognized as a promising hydrogen storage material because of its low cost and high capacity. However, the sluggish kinetics operating temperature hindered utilization. Herein, vanadium-substituted titanium-based bimetallic MXene (Ti3-nVnC2) was prepared to boost efficiency MgH2. The incorporation 5 wt % Ti2.2V0.8C2 dramatically decreased dehydrogenation MgH2 improved cyclic stability. MgH2-5 started release at 165 °C, it released 7.0 H2 in 30 min 220 °C took 5.3 2 h 75 showing excellent kinetics. In addition, activation energy MgH2-added 80.81 ± 3.29 kJ mol-1, which is lower than that most Ti-/or V-based catalyst-doped systems. Mechanism analysis reveals remarkably enhanced performance ascribed stable existence uniform distribution Ti-species (Ti0 Titanium hydride) V-species (V0 V5+), facilitated rapid absorption/desorption ensured This study offers valuable perspectives for assembly design catalysts within realm solid-state materials.
