Vanadium dopant has reported to enhance its photocatalytic properties toward visible light irradiation. However, vanadium doped TiO2 has several limitations for further practical application such as its low surface area and difficult in recycling due to its superfine particle. Supporting this material into porous and large surface material like zeolite material supposed to improve its photocatalytic properties. In this research, vanadium doped TiO2 (Ti0.997V0.003O2) photocatalyst was supported on Indonesian natural Zeolite using sonochemical method to study the structural and optical properties of supported photocatalyst. Ti0.997V0.003O2 was loaded into zeolite at various concentration ranging from 10 to 30 % w/w. The X-Ray Diffraction (XRD) data showed that Ti0.997V0.003O2/Zeolite at various concentrations have characteristic of anatase, rutile and mordenite phase structure. Infrared spectra showed the typical vibrational mode of TiO2 and mordenite phase. The sharp peak at 1370 cm-1 which is attributed to the lattice vibration of TiO2 became weaker due to vanadium dopant. The Raman spectra showed that the anatase vibration mode position shifted to higher wavenumber caused by the interaction between Ti0.997V0.003O2 and zeolite. Diffuse Reflectance Spectroscopy (DRS) data revealed that 15% of Ti0.997V0.003O2 on Zeolite has the highest visible light absorption and the lowest band gap energy (2.77 eV or 447 nm) in comparison to the others composition.[/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]Diffuse reflectance spectroscopy,Structural and optical properties,Supported photocatalyst,TiO2,Titanium dioxides (TiO2),Ultraviolet light irradiation,Visible light absorption,Visible-light irradiation[/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]anatase,photocatalyst,TiO2,vanadium,zeolite[/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]The authors gratefully acknowledge to Religion Ministry of Republic of Indonesia for providing research funding, BOPTN (Bantuan Operasional Perguruan Tinggi Negeri) in LP2M UIN Maulana Malik Ibrahim.[/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/622/1/012006[/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]
