Titanium (IV) ethoxide, zinc acetate (Zn(CH3COO)2.2H2O) and cobalt acetate (Co(C3COO)2.4H2O) were used as precursors. TiO2 and ZnO posses good photocatalytic ability in photodegradation of water pollutant. The disadvantage and weakness of photocatalytic reaction of TiO2 and ZnO mostly happens at ultraviolet range and less at visible light. This research aimed to decrease the disadventage of TiO2 and ZnO, using cobalt oxide. TiO2-ZnO-CoO nanocomposite photocatalyst was characterized by using SEM-EDS and XRD. SEM analysis showed homogenous and smooth morphology of TiO2-ZnO-CoO nanocomposite photocatalyst. EDS analysis revealed the TiO2-ZnO-CoO nanocomposite photocatalyst had O : Ti : Co : Zn = 32.64 : 37.39 : 11.85 : 18.12. In this study, we expose effect of amount of TiO2-ZnO-CoO nanocomposite photocatalyst, pH, and irradiation time on methylene blue dye photodegradation. Novel TiO2-ZnO-CoO nanocomposite photocatalyst was effective in photodegradation of methylene blue dye.[/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]Cobalt acetate,Irradiation time,Methylene blue dye,Photo-catalytic,Photocatalytic reactions,Photodegradation of methylene blue,Synthesis and characterizations,Water pollutants[/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][/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/10.1088/1755-1315/60/1/012015[/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]
