The research procedures include caustic fusion process involving the mixing of NaOH and ilmenite with a ratio of 1: 4 at 650°C for 120 minutes. The result from this caustic fusion process, i.e. frit, was then washed with water and followed by acid leaching using sulfuric acid 45% to obtain precursor TiOSO4. This precursor was then hydrolyzed to produce white precipitates in the form of sol TiO(OH)2 which was then condensed for 24 hours. The precipitate was washed and dried before calcined at a temperature of 500°C for 1 hour. X-ray diffraction (XRD) and scanning electron microscopy coupled with energy dispersive X-ray spectroscopy (SEM-EDX) analysis is included to show the phases, morphology and the final composition of the synthesized TiO2 powder. UV-Vis Spectrometry was also used to calculate the band-gap energy and the photocatalytic ability of the synthesized TiO2 in the purification process of rhodamin-B.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]caustic fusion,Fe dopant,ilmenite extraction,photocatalyst,titanium dioxide powder[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1063/1.4974421[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
