Description

Currently, bimetallic nanoparticles are of great interest due to their optical, electronic and magnetic properties, since these can be improved compared to their monometallic counterparts. The applications of this type of nanoparticles in industry are of great relevance. For example, in medicine they are used for the treatment of cancer and are also used for water treatment through photocatalysis. In this work, the synthesis of titanium and iron nanoparticles was carried out using the ultrasonic cavitation method, with the purpose of analyzing their properties and composition. For this, three different types of characterization were carried out: TEM to know its composition and structure, RBS to rectify composition and XRD to rectify structure. According to the results obtained from TEM, a composition of iron and titanium oxide nanoparticles was found, with iron found in nanowire structures of approximately 100 nm. This result was corroborated by RBS analysis using a proton beam at 1.5 MeV and also by XRD analysis, where peaks corresponding to different crystal phases of iron and titanium oxides, like ferrite, were detected. Once the properties of the nanoparticles were established, they were subjected to an annealing process, at a temperature of 800°C for 1 hour, to see the effect of a thermal treatment. Thanks to a new XRD analysis, it was observed that after annealing, a simple tetragonal phase was reached for titanium, known as rutile.
