“…The latter observation, in particular, indicates minimal (if any) formation of intermediate oxidation states of Mo, which can be readily observed by XPS in nanostructured Mo‐based catalysts [38] . In C 1s region, presented in Figure S4, we do not observe any significant modification after TOS testing [39,40] …”

The cost‐effectiveness and excellent performance of conductive‐carbon‐supported Ni‐based electrocatalysts make them attractive materials for hydrogen oxidation and evolution reactions. However, they were previously unused in gas‐phase hydrogenation reactions. In this work, we have expanded the applicability of commercially available advanced Ni/C, NiMo/C and NiRe/C materials from electrocatalysis to heterogeneous catalysis of CO2 methanation. Our catalytic testing efforts indicate that the monometallic Ni/C material demonstrates the best CO2 methanation properties, achieving an excellent CO2 conversion of 83 % at 400 °C with nearly complete selectivity to CH4 of 99.7 %, plus exhibiting intact performance during 90 h of time‐on‐stream testing. Such catalytic properties are among the highest reported to date among carbon‐supported Ni‐based methanation catalysts. Excellent performance of Ni/C stems from the good dispersion of the Ni nanoparticles over N‐containing carbon support material.

“…In addition, the heterogeneous catalyst can be easily recycled several times without obvious loss of activity and selectivity. Kolen'ko et al 32 synthesized RuO 2 nanoparticles and clusters anchored on TpBD-Me 2 COF as an active and selective catalyst for selective formic acid dehydrogenation. Vaidhyanathan and co-workers 33 loaded Co/Co(OH) 2 nanoparticles onto the methoxy-functionalized highly stable COF (IISERP-COF5), and the as-prepared heterogeneous catalyst exhibited remarkable catalytic performance toward reduction of nitro/nitrile compounds in the presence of readily available and safe NaBH 4 under ambient conditions with good yield, selectivity, and recyclability.…”

Developing non-noble metal-based catalysts with excellent performance for selective hydrogenation of alkynes under mild reaction conditions is highly desirable but still faces challenges. Herein, a non-noble nickel-modified covalent organic framework (Ni/COF) had been synthesized through a facile post-modified method and followed by reduction at a different temperature under a H2/Ar atmosphere. The as-prepared catalysts were characterized by X-ray diffraction, high-resolution transmission electron microscopy, X-ray photoelectron spectroscopy, Brunauer–Emmett–Teller, and Fourier transforms infrared, and the optimal H350–Ni/COF presents excellent catalytic performance in the semihydrogenation of a series of aromatic terminal alkyne substrates, particularly in the partial hydrogenation of phenylacetylene with nearly full conversion and 85% selectivity toward styrene under mild reaction conditions (10 bar of H2, 100 °C, and 1 h). Moreover, such a catalyst also exhibited satisfying stability after three consecutive cycles.
