They were calcined at 500 to 700 °C and then characterized by X-ray Diffraction (XRD), Energy Dispersive X-ray Fluorescence (EDXRF), Scanning Electron Microscope-Energy Dispersive X-ray (SEM-EDX). The XRD results suggested that the pure TiO2 powder formed at 500 °C was in the anatase phase, whereas the materials formed at 600 were mixing of a few anatase phases and rutile phases, and a pure rutile phase at 700 C. Therefore, the phase transition temperature of TiO2 was 600 °C in this synthesis. The average crystallite sizes of prepared TiO2 range from 25.50 to 96.39 nm. The average crystallite size was increased with increasing calcined temperature. The other path followed is the study of the addition of AgNO3 to the TiO2 (doping) through ions materials by XRD analysis were synthesised by the sol-gel method using titanium tetra isopropoxide, isopropanol, and silver nitrate and calcined at 500 to 700 °C. The presence of silver in the TiO2 network has been established by XRD and SEM-EDX techniques. The XRD results of prepared Ag-TiO2 materials suggested that the anatase phase in the tetragonal crystal structure at 500 °C and pure rutile phases appeared to be the predominant phase of rutile in the tetragonal crystal structure at 600 °C and 700 °C. The average crystallite sizes of prepared Ag-TiO2 materials by XRD analysis were in the range of 15.79 to 54.53 nm. Thus, the prepared Ag-TiO2 nanoparticles of pure anatase phase and pure rutile phase were calcined at 500 C and 700 C. The XRD study revealed that the prepared TiO2 and Ag-TiO2 materials were nanomaterials and anatase and rutile phases of a tetragonal crystal system."}]},"item_1583103108160":{"attribute_name":"Keywords","attribute_value_mlt":[{"interim":"TiO2 nanoparticles"},{"interim":"Ag-TiO2 nanoparticles"},{"interim":"sol-gel method, phase transition"}]},"item_1583103120197":{"attribute_name":"Files","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-02-12"}],"displaytype":"preview","filename":"Hay Mar Oo (273 to 282).pdf","filesize":[{"value":"824 KB"}],"format":"application/pdf","licensetype":"license_0","url":{"url":"https://meral.edu.mm/record/9299/files/Hay Mar Oo (273 to 282).pdf"},"version_id":"c1ab4361-82d4-4866-8d5b-07d496f13097"}]},"item_1583103131163":{"attribute_name":"Journal articles","attribute_value_mlt":[{"subitem_issue":"2022","subitem_journal_title":"University of Yangon Research Journal","subitem_pages":"273-282","subitem_volume":"11, No. 1"}]},"item_1583105942107":{"attribute_name":"Authors","attribute_value_mlt":[{"subitem_authors":[{"subitem_authors_fullname":"Hay Mar Oo"},{"subitem_authors_fullname":"Hlaing Hlaing Oo"},{"subitem_authors_fullname":"Cho Cho"}]}]},"item_1583108359239":{"attribute_name":"Upload type","attribute_value_mlt":[{"interim":"Publication"}]},"item_1583108428133":{"attribute_name":"Publication type","attribute_value_mlt":[{"interim":"Journal article"}]},"item_1583159729339":{"attribute_name":"Publication date","attribute_value":"2022-12-31"},"item_title":"Synthesis and Characterization of TiO2 and Ag Doped TiO2 Nanoparticles by Sol-Gel Method","item_type_id":"21","owner":"12","path":["1582967633684"],"publish_date":"2024-02-12","publish_status":"0","recid":"9299","relation_version_is_last":true,"title":["Synthesis and Characterization of TiO2 and Ag Doped TiO2 Nanoparticles by Sol-Gel Method"],"weko_creator_id":"12","weko_shared_id":-1},"updated":"2024-02-12T09:33:04.510911+00:00"}
