In this study, the retention substance bentonite was used in preparation of a mesoporous silica nanocatalyst. The analysis sorbents from sorption isotherm study and results obtained were summarized. Also discussed are chemical composition Navbahor deposit, types sorbent isotherms by adsorption various gases on sorbents, descriptions phase samples synthesized textures, physic-chemical characteri...

Abstract Achieving superior performance of nanoparticle systems is one the biggest challenges in catalysis. Two major phenomena, occurring during reactions, hinder development full potential catalysts: sintering and contamination with carbon containing species, sometimes called coking. Here, we demonstrate that Ir nanocrystals, arranged into periodic networks on hexagonal boron nitride (h-BN) s...

Alarming environmental changes and the threat of natural fuel resource extinction are concerning issues in human development. This has increased scientists’ efforts to phase out traditional energy resources move on environmentally friendly biofuels. In this study, non-edible castor oil was transesterified with methanol using a manganese-doped zinc oxide (Mn-doped ZnO) nanocatalyst. A heterogene...

TiO2–FeZn nanocatalyst combined with sonolysis were used to activate peroxymonosulfate (PMS) as a highly efficient advanced oxidation process (US/TiO2–FeZn/PMS) for the decoloration of orange II dye (OII) and real textile wastewater. The characterization as-synthesized NPs was performed by SEM, FTIR, EDX XRD analyses. Optimal experimental conditions operational parameters obtained: pH = 3, 15 m...
