Introduction In the past few decades, the use of heteropolyacids (HPAs) as catalysts has become a significant area of research. HPAs have received much interest in the area of acid and oxidation catalysis because of their

Introduction Bi-component catalysts including platinum group metals and heteropoly compounds are used in the oxidation of hydrocarbons [ 1 ]. Catalytic action depends on the composition and the inherent interaction between

nitrate on decomposition gives rise to oxides of nitrogen and oxygen as detected by TG–MS (Scheme 1 ) which in turn would oxidize the liberated ammonia [ 2 ]. In TG curve, simultaneous deamination and decomposition appear as a single stage whereas in DTA

Introduction In the field of thermal plasma deposition, it has been recently shown [ 1 ] that the pre-oxidation of steel substrates enhanced the adhesion of ceramic coatings, compared with the classical method, where the

atmosphere, this mass increase and the corresponding heat released can be related to molybdenum oxidation. The results obtained from the phase studies ( Fig. 2 ) also prove the presence of (MoO 2 ) oxide products resulting from this reaction among the

Introduction The selective oxidation of alkylbenzenes with a green oxidant (molecular dioxygen) to oxygen-containing compounds such as alcohols, ketones and carboxylic acids is a very important industrial process. Traditional

materials are likely to contain additives such as wood preservatives, coatings, and fire-retardants. Wood preservatives contain metal oxides that can generally act as a catalyst [ 1 – 4 ]. Copper(II) oxide (CuO) is a major component of wood preservatives and
