Hydrogen migration as a potential driving force in the thermal decomposition of dimethoxymethane: New insights from pyrolysis imaging photoelectron photoion coincidence spectroscopy and computations

Autor: Andras Bodi, Xiangkun Wu, Tongpo Yu, Xiaoguo Zhou, Patrick Hemberger

Publikováno v: Combustion and Flame. 222:123-132

Pyrolysis and low-temperature oxidation of dimethoxymethane (methylal, MeOCH2OMe) play an important role in the ignition of blended diesel fuels, but the underlying mechanisms are still debated. In these kinetic models, bimolecular hydrogen abstracti

Publikováno v: Journal of Catalysis. 382:347-357

Heterogeneous single-metal-site catalysts (HSMSCs) have been attracting increasing interest because of their unique traits. However, deactivation induced by metal agglomeration restrains the application especially when they have high metal loading. H

Dissociative photoionization of CF3Cl via the C2E and D2E states: competition of the C–F and C–Cl bond cleavages

Autor: Fuyi Liu, Xinhua Dai, Xiaoguo Zhou, Liusi Sheng, Xiangkun Wu, Shilin Liu, Tongpo Yu, Yan Chen

Publikováno v: Physical Chemistry Chemical Physics. 21:4998-5005

The dissociative photoionization of CF3Cl was investigated using threshold photoelectron photoion coincidence (TPEPICO) imaging in the energy range of 12.30–18.50 eV. The coincident time-of-flight mass spectra and three-dimensional time-sliced imag

Publikováno v: Chemical Physics Letters. 785:139144

We investigate single photon double ionization (spDI) of substituted benzenes (toluene, chlorobenzene and fluorobenzene) in photon energy of 20–40 eV. We observe that a resonance-like enhancement of spDI, which deviates from the prediction of the �
