“…Thus, these catalysts facilitated cracking instead of the deCOx pathway and increased the formation of light hydrocarbons. 55 Our previous TPD-CO 2 analysis (Table 4) showed that Ni 10 -Mg 15 /MWCNT and Ni 10 -Mn 5 /MWCNT produced a high total amount of basic sites with 2162 and 2925 mmol g À1 , respectively. Other studies have also indicated that basic sites play a major role in promoting decarboxylation by retarding coke formation via a decrease in the deactivation rate of acidic catalysts.…”

“…MoO 3 is also used as a catalyst in the industrial production of acrylonitrile from propylene and ammonia. However, the constant interest in nanomaterials has made also nano MoO 3 attractive, which has been proven to be a promising candidate in many fields, e.g., (photo)catalysis, gas sensing, electrochemical cells, or even in forensic science and photothermal therapy [1][2][3][4][5][6][7][8][9][10][11][12][13].…”

Effects of different reaction parameters in the hydrothermal synthesis of molybdenum oxides (MoO3) were investigated and monoclinic (β-) MoO3 was prepared hydrothermally for the first time. Various temperatures (90/210 °C, and as a novelty 240 °C) and durations (3/6 h) were used. At 240 °C, cetyltrimethylammonium bromide (CTAB) and CrCl3 additives were also tested. Both the reaction temperatures and durations played a significant role in the formation of the products. At 90 °C, h-MoO3 was obtained, while at 240 °C the orthorhombic (α-) MoO3 formed with hexagonal rod-like and nanofibrous morphology, respectively. The phase transformation between these two phases was observed at 210 °C. At this temperature, the 3 h reaction time resulted in the mixture of h- and α-MoO3, but 6 h led to pure α-MoO3. With CTAB the product was bare o-MoO3, however, when CrCl3 was applied, pure metastable m-MoO3 formed with the well-crystallized nanosheet morphology. The gas sensing of the MoO3 polymorphs was tested to H2, which was the first such gas sensing study in the case of m-WO3. Monoclinic MoO3 was found to be more sensitive in H2 sensing than o-MoO3. This initial gas sensing study indicates that m-MoO3 has promising gas sensing properties and this MoO3 polymorph is promising to be studied in detail in the future.

“…Recently, number of studies in the literature have investigated with catalytic effect over sulfide or non-sulfide form of mono-or bi-metals over the metal oxides like Al2O3, SiO2, activated carbon, alumino-silicates and zeolite [14][15][16][17][18][19][20][21][22][23][24]. In few studies, activated carbon has been investigated over methyl or ethyl esters, which produced low pour-point property of diesel-like fuel, but had higher reaction rate on DCA than HDO [15][16][17].…”

Hydrodeoxygenation of vegetal oil and methyl oleate studied using Pt and Pd supported with alumina-beta-zeolite (a-Al2O3-H-a) and comparing its performance with NiMo/a-Al2O3 and Pd/C in a semi-batch reactor, at 300 - 340 oC and 2.0 MPa. This study has used Pd and Pt on H-a zeolites with alumina binder as extrudate and it examines over triglycerides hydrogenolysis. Pd/C showed higher rate of deoxygenation and the selectivity of C18/C17 was higher for NiMo-S/a-Al2O3 and PdPt/a-Al2O3-H-a. PdPt/a-Al2O3-H-a enhanced the hydrogenation and hydrogenolysis, while conversion and yield in deoxygenation and decomposition has reached identicical performance as NiMo-S/a-Al2O3 catalytic deoxygenation process. Both the thermal decomposition and the hydrogenation of unsaturated triglycerides were mainly affected by H2 partial pressure. Transition metals like Pd and Pt on H-a and alumina binder ratio of 40:60 wt% showed effective hydrodeoxygenation of vegetal oil without substituting sulfur feed.
