Selective nano alumina supported vanadium oxide catalysts for oxidative dehydrogenation of ethylbenzene to styrene using CO2 as soft oxidant

Process Development and DFT‐Assisted Mechanism of the Vapour Phase Ammoxidation of 2,6‐Dichlorotoluene to 2,6‐Dichlorobenzonitrile over the V2O5/γ‐Al2O3 Catalyst

“…The specific surface area and the total volume of mesoporous Al 2 O 3 are 188 m 2 g −1 and 0.62 cm 3 g −1 , respectively. After the V 2 O 5 modification however, a decrease in the value of the surface area and pore volume was observed with increasing vanadium ratio . This is attributed to the partial blockage of catalyst pore by vanadium species during the preparation of the V 2 O 5 /γ‐Al 2 O 3 catalysts.…”

“…(Gregg and Sing 1982) . The BET surface areas and textural properties of the catalyst having different vanadia loading are presented in Table .…”

“…SEM analysis of AlV20 catalyst was carried out under different magnifications which are shown in Figure A. SEM image reveals that the agglomerated spheroidal vanadium oxides particles were homogeneously deposited on the γ‐Al 2 O 3 support surface …”

Flower-shaped ALOOH nanostructures synthesized by the reaction of an AlN/Al composite nanopowder in water

“…Currently, the synthesis of alumina nanoparticles for use in adsorption [1,2], catalysis [3][4][5] composite materials [6], biomaterials [7], and additives to pigments and dyes [8] is an actively developing scientific direction at the interface of physical chemistry and nanotechnology. Typically, alumina nanoparticles are produced by a sol-gel method [9], hydrothermal method or mechanosynthesis.…”

Hydrotreating Activity of Co-Mo/Al2O3 Promoted with Boron and Phosphorous

“…The effect of boron addition to essential activity of the CoMo-S structure supported on Al2O3, we have shown [15,16] that the addition of an appropriate amount of boron (about 0.6 wt% B) weakens the interactions between the surface of oxides molybdenum and alumina [17].…”
