One pot-synthesis of the fourth category of dinuclear molybdenum(VI) oxalate series: Structure and study of thermal and redox properties

“…SI4, in Supporting information) indicate the presence of oxomolybdic fragments. The (Mo]Ot) stretching modes are observed at 921, 894 and 858 cm −1 for compound (1), 933 and 863 cm −1 for compound (2) and 921 and 873 for compound (3) [36][37][38]. The positions of these bands are consistent with their counterparts in the IR spectra.…”

“…Raman spectroscopy is an appropriate and highly efficient to ol for the identification o f o xomolybdenum s pecies [32][33][34][35][36][37][38]. T he R aman absorption bands in the 1000-600 cm −1 region (See Fig.…”

“…The positions of these bands are consistent with their counterparts in the IR spectra. At lower wavenumbers the bands between 800 and 650 cm −1 are typical for the vibrations of double-bridged MoeOeMo modes [36][37][38]. At higher frequency, the CeO stretching vibrations of the oxalate ligands (1450-1430 cm −1 for the symmetric modes and 1660-1690 for the antisymmetric modes) and the CeH stretching vibrations of the ammonium cations (3000-2800 cm −1 ) range contribute [39].…”

Deoxygenation of Palmitic Acid to Produce Diesel-like Hydrocarbons over Nickel Incorporated Cellular Foam Catalyst: A Kinetic Study

“…Among others, catalytic deoxygenation of fatty acids as renewable resources can be a potential technology to synthesize diesel-like hydrocarbons. During fatty acid deoxygenation, n-alkanes and alkenes will be produced through decarboxylation and decarbonylation [3] reactions, respectively; Decarboxylation: C n H (2n+2) COO → C n H 2n+2 +CO 2 (1) Decarbonylation: C n H (2n+2) COO → C n H 2n +CO+H 2 O…”

Effect of precursor acidity on zeolite supported Pd catalyst properties and hydrodeoxygenation activity for the production of biofuel

“…The presence of the iso-C 18 H 38 was due to FPd/Z increased acidity.Previous studies [32,35]have shown that catalysts with increased acidity are highly favorable forparaffinskeletal isomerization. Typically, the presence of isomerized product is considered an advantage due to the ability of iso-paraffin fractions to lower the biofuel freezing point by about 20 ºC since n-paraffin (C 16 -C 18 ) has comparable high freezing point (between 18 ºC and 28 ºC) which is a disadvantage to their cold flow properties such as cold filter plugging point [32,38]. The increased iso-C 18 H 38 content in FPd/Z compared to Pd/Z was unarguably due to the fluoride ion functionalizationwhich further increased the acidity of FPd/Z.…”
