Efficient hydrothermal deoxygenation of methyl palmitate to diesel-like hydrocarbons on carbon encapsulated

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 2,   Pages 139-155 doi: 10.1007/s11705-022-2217-4

Abstract: Porous carbon-encapsulated Ni and Ni–Sn intermetallic compound catalysts were prepared by the one-potextended Stöber method followed by carbonization and tested for in-situ hydrothermal deoxygenationcatalysts than in carbon-encapsulated Ni catalysts.During the in-situ hydrothermal deoxygenation, the synergism between Ni and Sn favors palmiticparticles under harsh hydrothermal conditions.

Frontiers of Chemical Science and Engineering 2016, Volume 10, Issue 1,   Pages 103-107 doi: 10.1007/s11705-015-1552-0

Abstract: Water induced decomposition of Cu (BTC) (BTC= benzene-1,3,5-tricarboxylate) metal-organic framework (MOF) was studied using dynamic water vapour adsorption. Small-angle X-ray scattering, Fourier transform infrared spectroscopy and differential scanning calorimetry analyses revealed that the underlying mechanism of Cu (BTC) MOF decomposition under humid streams is the interpenetration of water molecules into Cu-BTC coordination to displace organic linkers (BTC) from Cu centres.
