要点3.电化学原位FTIR光谱和理论计算表明,特殊的p-d杂化作用和拉伸应变效应能有效地降低C-C键断裂活化能,加速CO*氧化,促进EG的完全氧化,提高催化剂的催化性能。 Yuchen Qin, et al, Extraordinary p-d Hybridization Interaction in Heterostructur...
(Princeton Applied Research). All spectroscopic measurements were collected with 4 cm−1resolution and at least 128 coadded scans using a FTIR spectrometer (Nicolet iS50, Thermo Scientific) equipped with a liquid nitrogen-cooled MCT detector. Nuclear magnetic resonance spectra were collected on ...
Decomposition via C-C bond scission and reaction with O_2 are competing fates of the cyclohexoxy radical. In 700-750 Torr total pressure at 296 +- 2K, the rate constant ratio k_(decomp)/k_(O2) = (8.1 +- 1.5) * 10~(18) molecule cm~(-3). At 296 K in 1 atm of air, 61% ...
Lignin depolymerisation via photocatalytic cleavage of the selective interunit linkage in lignin could be a sustainable approach to produce monomeric aromatic chemicals. However, the insufficient investigation of interunit C–C bond fragmentation has obstructed the rational design of efficient photocatalytic ...
