All rights reserved.Surface area has significant impact on the photocatalytic activity of semiconductor material. It was found that templates as structure directing agent played a role in regulating the surface area of materials. The most widely used as template is cetyltrimethylammonium bromide (CTAB) surfactant. In this research, TiO2 was prepared by solvothermal method used temperature variations of 150, 175, 200, and 225 °C. The X-ray powder diffraction (XRD) data indicated that anatase phase of TiO2 was successfully obtained with I41/amd space group and as the synthesis temperature was increased, the crystallinity increases. The spectra infrared spectroscopy (IR) showed the broad peak situated at wavenumber 400-800 cm-1 which was assigned to the stretching Ti-O vibration. Raman spectra showed peaks at wavenumber 145, 197, 397, 516, and 639 cm-1 which were attributed to vibration modes of anatase. The scanning electron microscopy (SEM) image demonstrated the morphology particle has homogeneous distribution and irregular shape. Furthermore, Brunauer-Emmett-Teller (BET) specific surface area showed the CTAB-assisted TiO2 which was synthesized at 175 °C has the highest surface area of 227.043 m2/g in this research among the others.[/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]Cetyltrimethylammonium bromide,CTAB,Homogeneous distribution,Scanning electron microscopy image,Solvothermal,Structure directing agents,Surface area,TiO2[/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]CTAB,solvothermal,surface area,TiO2[/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]This project was financially supported by Penelitian Kompetitif Mahasiswa (PKM) Faculty Science and Technology, Universitas Islam Negeri Maulana Malik Ibrahim Malang2018.[/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/10.1088/1757-899X/546/4/042003[/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]
