WebOct 16, 2013 · On bare surfaces, C-H bonds cleave via oxidative addition, involving Pd atom insertion into the C-H bond with electron backdonation from Pd to C-H antibonding states and the formation of tight three-center (H3C···Pd···H)(‡) transition states. WebMay 1, 2024 · An electrocatalyst synthesized by solution deposition of amorphous Pd δ+ clusters (Pd 3δ+ and Pd 4δ+) onto mildly oxidized carbon nanotubes (Pd δ+ -OCNT) shows nearly 100% selectivity toward H 2 O 2 and a positive shift of ORR onset potential by ~320 mV compared with the OCNT substrate.
WebDec 28, 2016 · Increasing the basicity of metal center leads to stronger electron backdonation to H–H σ* orbital, which further improves H 2 activation (the cleavage of H–H bond). This process is essentially oxidative addition of two hydrides to the metal center, and as a consequence the oxidation state of metal center increases by two. WebInfrared and density functional theory studies revealed that the highly efficient hydrogenation is due to the favorable activation of the carbonyl moiety of furfural derivatives through the backdonation to its π* orbital from the Co d -electrons.
