The cooling system of an Automobile plays an important role in its performance, consists of two main parts, known as radiator and fan. Improving thermal efficiency of engine leads to increase the engine's performance, decline the fuel consumption and decrease the pollution emissions. Water and ethylene glycol as conventional coolants have been widely used in radiators of an automotive industry ...

Zinc ferrite (ZnFe2O4), one of the major forms zinc in electric arc furnace dust and leaching residue, is very difficult to chemically dissolve either acidic or alkaline solutions. It therefore necessary study extraction from achieve full recovery resources. In this paper, CaO was used degrade structure then ammonia method applied recover zinc. The thermodynamic analysis indicated that could re...

The selective oxidation of tetrahydrofuran (THF) to gamma-butyrolactone (GBL) on spinel ZnFe2O4 nanoparticles (ZFNPs) was investigated. catalyst prepared with the coprecipitation method and characterized by FTIR, XRD, TEM, SEM, EDS, TGA, XPS, BET surface area. characterization techniques showed that a nonuniform spherical spinal oxide an average particle size 26 nm formed. reaction carried out ...

Severe surface photocarrier recombination and poor electronic conductivity are the major factors behind sluggish photoelectrochemical water oxidation kinetics of ZnFe2O4 photoanode. Here, CeOx catalyst overlayer has been coupled with reduced nanorods (NRs) to reduce charge on photoanode significantly. The density functional theory (DFT) studies indicate that oxygen vacancy defect-rich construct...

ZnFe2O4 microspheres were prepared by solvothermal method, and a novel ZnFe2O4@TiO2 core-shell composite photocatalyst was ultrasonic (denoted as ZT-x) mechanical stirring ZTM-1.2). The morphology, structure, magnetic, optoelectronic properties of the catalyst investigated comprehensively, degradation performance explored through photocatalytic Rhodamine B (RhB) under UV light. concentration Rh...
