Nanomagnetic NiFe2O4 was used as the efficient, stable, reusable catalyst for selective oxidation of alcohols to their corresponding carbonyl compounds using oxone (potassium hydrogen monopersulfate) as oxidant in the presence of water as solvent at room temperature. The oxidation of various primary and secondary alcohols has been examined and related corresponding products were obtained wi...

Bulk boron materials, such as hexagonal nitride (h-BN), are highly selective catalysts for the oxidative dehydrogenation of propane (ODHP). Previous attempts to improve productivity these systems involved immobilization on silica and resulted in less catalysts. Here, we report that acid-treated, activated carbon-supported prepared via incipient wetness impregnation with boric acid (B/OAC) exhib...

Supported vanadia catalyst was successfully synthesized using wet impregnation of gamma-Alumina to study Propane Oxidative Dehydrogenation (POD). The prepared catalysts were characterized with XRD, BET, and TPR tests. In a broad temperature range (340 to 630°C), effects of vanadia loading (2.7, 5.4, and 9 wt%) and propane to oxygen ratio (3/1 to 1/3) were investigated on propane conversion as w...

Abstract The catalytic oxidative dehydrogenation of propane (ODHP) is a challenging reaction due to facile competing overoxidation CO x . gaseous disulfur molecule, S 2 , isoelectronic with O and has been shown act as an alternative, “soft oxidant” for the analogous process (SODHP) over bulk metal sulfide catalysts. However, these catalysts suffer from low surface areas ill‐defined active sites...

The reaction of NH2 radicals with C3H8 is crucial for understanding the combustion behavior NH3/C3H8 blends. In this study, we investigated temperature dependence rate coefficients hydrogen abstraction reactions by using high-level theoretical approaches. potential energy surface was constructed at CCSD(T)/cc-pV(T, Q)//M06-2X/aug-cc-pVTZ level theory, and were computed conventional transition s...

An efficient protocol for the selective oxidation of primary alcohols to aldehydes withH5IO6/V2O5 in ionic liquid [bmpy][PF6] has been developed. High yields of the products, mildreaction conditions and simple experimental procedure make this protocol complementary tothe existing methods. The catalyst can be reused for several times without obvious loss of thecatalytic activity.

Microorganisms that biosynthesize broad-specificity oxygenases to initiate metabolism of linear and branched-chain alkanes, nitroalkanes, cyclic ketones, alkenoic acids, and chromenes were surveyed for the ability to biodegrade trichloroethylene (TCE). The results indicated that TCE oxidation is not a common property of broad-specificity microbial oxygenases. Bacteria that contained nitropropan...
