Carbon Nanofibers Supported Ultra-Small Palladium Oxide Nanoclusters as an Efficient and Continuable Catalyst for Suzuki Coupling Reaction

Stabilization of palladium nanoparticles inside chitosan derived N‐doped carbon nanofibers for Heck reaction

“…The Raman spectra had two bands at 1348 and 1589 cm −1 , which were known as D band and G band, respectively. The D band at 1348 cm −1 could be attributed to the disordered carbon atoms with the sp 3 electronic structure of graphitic carbon while the G band at 1589 cm −1 could be ascribed to in‐plane vibrations of sp 2 carbon 20,35 . The intensity of ratio of the D band to the G band (I D /I G ) could be used to characterize the disordered degree of carbon materials.…”

“…The D band at 1348 cm À1 could be attributed to the disordered carbon atoms with the sp 3 electronic structure of graphitic carbon while the G band at 1589 cm À1 could be ascribed to in-plane vibrations of sp 2 carbon. 20,35 The intensity of ratio of the D band to the G band (I D /I G ) could be used to characterize the disordered degree of carbon materials. When the annealing temperature was increased from 400 to 800 C, the I D /I G ratio decreased from 1.05 to 0.86, which implied an increased ratio of graphitized carbon under higher carbonization temperature.…”

New Palladium – ZrO2 Nano‐Architectures from Thermal Transformation of UiO‐66‐NH2 for Carbonylative Suzuki and Hydrogenation Reactions

“…[35,36] The high catalytic activity of PdO supported on different materials was also reported. [37][38][39][40][41] For example, PdO on graphene oxide [37] and PdO x on NiO [29] were found to be better catalysts than Pd/C. Advantages of PdO catalysts dispersed on the CNFs surface, [38] carbon nanotubes, [39] CeO 2 [40] or Ce x O y [41] were underlined.…”

Our studies were aimed at the comparison of the catalytic activity of Pd-1 precursor and composites obtained by its pyrolysis.…”

Heterogeneous catalysis by ultra-small bimetallic nanoparticles surpassing homogeneous catalysis for carbon–carbon bond forming reactions

“…21 By controlling these parameters and careful selection of the support, such catalysts have the potential to rival their homogeneous counterparts in terms of activity and stability. [22][23][24] Although considerable advances have been made in this area, only very few catalysts have activity comparable to established homogeneous catalysts. 6,[25][26][27] Thus, there is an urgent need for highly active heterogeneous catalysts for SCC reactions.…”
