Generation of active oxygen species on solid surfaces. Opportunity for novel oxidation technologies over zeolites

Recent decades show impressive progress in oxidation catalysis, resulting in many novel industrial technologies. However, there is a difficult and challenging field, that of oxidation reactions which cannot be selectively implemented via traditional approaches. In the present paper, we discuss recent progress achieved in this particular field through the discovery of unique oxidation chemistry involving nitrous oxide.

Active oxygen in selective oxidation catalysis

Owning to its biobased organic acid, low cost and multiple reactive functionalities as it contains both one carboxylic acid group and hydroxyl group, lactic acid has been described as a commodity chemical sleeping giant. In this review, the conversion of lactic acid to other important commodity chemicals, such as, poly L‐lactic acid, acrylic acid, 2, 3‐pentanedione, pyruvic acid, propanoic acid, 1, 2‐propanediol, acetaldehyde, ethyl lactate, using chemical or biological catalysts, and the economy analysis of conversions are depicted. The conversion would provide a new way for the solution of the present oil crisis.

Properties of oxygen sites at the MoO_3(010) surface: density functional theory cluster studies and photoemission experiments

Partial oxidation of acrolein is a commercially important reaction, its product—acrylic acid—being widely used industrially for producing resins, dyes, glues, nonwoven fabrics, etc. Partial oxidation of acrolein is also a convenient model reaction because: (1) the number of reaction products is moderate (CO, CO2, acrylic acid) and (2) their difference in acid-base properties from the starting material makes it possible to select desirable catalysts by applying directly and efficiently Boreskov's concept of intermediate chemical interaction of a catalyst with reaction mixture components. According to this concept [1], the transformation of surface intermediates (SI) formed in the interaction of reactants with a catalyst's surface is determined by the structure and bond energy of these SI. The study of the reaction mechanism includes determination of structures and energy characteristics of the surface intermediates and the elucidation of their connection with catalyst chemical composition and reac...
