Background: Ceria (CeO2) is the focus of constant and diverse research interest due to its wide industrial applications. In particular, ceria-based mixed oxides with nanostructures exhibit better catalytic properties owing to high specific surface area, improved sintering properties and high oxygen storage-release characteristics in comparison to the individual bulk materials. This work is aimed at analyzing the significance of Read More

Background: Acid catalysis of alkanes is very important as it is the basis of refining. They can be converted into other alkanes or alkenes by isomerization, cracking or alkylation. Heteropolyacids have unique acid - base and redox properties, which render them valuable in a number of applications. Their strong acidity makes them attractive candidates to tackle the current challenges in alkanes. The aim of this review is Read More

Background: The development of theoretical insights into heterogeneous catalysis is hindered by the lack of knowledge on the detailed reaction mechanisms. In order to gain such knowledge, it is important to collect information on the nature of intermediates, and their reaction ability Methods: The spectrokinetic method is successfully applied to the studies of intermediates in heterogeneous catalytic reactions. Results: Read More

Background: Selective oxidation of chemical warfare agent (CWA) simulants including the 2-chloroethyl ethyl sulfide (2-CEES) and other analogs through a green method in the presence of keplerate Cu20-Polyoxotungstate [Cu20Cl(OH)24(H2O)12(P8W48O184)]25- supported on magnetic nanoparticles was investigated. Keplerate nano-polyoxometalates, a new class of polyoxometalates which commonly known as “Giant”, Read More

Background: Dehydrozingerone is a biosynthetic intermediate and structural analog of curcumin. It is a flavoring ingredient and has antioxidant and antimutagenic properties. Dehydrozingerone can be efficiently synthesized from vanillin and acetone by cross-aldol (or Claisen-Schmidt) condensation using heterogeneous base catalysts. Vanillin can be sourced from the valorization of biomass. Green chemistry aspects su Read More

Background: There are various conventional ways for the synthesis of aromatic ketones but suffer from disadvantages like the use of toxic reagents, stoichiometric reagents producing huge amount of byproducts, thus causing hazard to the environment, whereas homogeneous protocols or the noble metal which support catalytic processes are not economically viable. On this ground, an effort was made to devel Read More

Background: V2O5 is significantly soluble in water so the use of this oxide or mixed oxides systems based on V2O5, in photocatalytic processes in water, may release vanadium species in the aqueous medium, generating a certain amount of additional contamination. The present report is devoted to study the physical-chemical properties of V2O5-TiO2 composition and its use in photocatalytic processes in aqueous media. T Read More

Background: Utilization of crude glycerol obtained during the bio-diesel production for the synthesis of fine chemicals and fuel additives by catalytic routes is very important from cost-effective and environmental perspectives. Among all alkylpyrazines, the 2,6-DMP is one of the valuable compounds for the production of various agro-chemicals, food flavoring agent and as a ligand for catalyst synthesis. In this study, 2,6-di Read More
