However, oxidation potential of g-C3N4 is not enough for water oxidation. Therefore, we focused on hybridization of g-C3N4 and tungsten(VI) oxide (WO3) which has high oxidation potential for water oxidation. In this study, we examined CO2 reduction by composite photocatalyst of g-C3N4 and WO3, which was prepared by three methods (mixture using an agate mortar, impregnation and planetary mill). As a result, composite photocatalyst prepared with planetary mill showed the highest photocatalytic activity. Photodeposition of silver or gold nanoparticles only on g-C3N4 of the hybrid photocatalyst induced an increase in CH3OH because the loaded metal nanoparticles play an important role in multi-electron reduction of CO2. Photocatalytic activity of the Au-loaded hybrid photocatalyst composed of g-C3N4 and WO3 was 1.7-times higher than that of the hybrid photocatalyst without Au loading. In addition, we investigated photocatalytic reaction mechanism of composite photocatalyst by double-beam photoacoustic spectroscopy. This result revealed Z-scheme reaction proceeds in the composite photocatalyst to maintain high oxidation ability of WO3 and high reduction ability of g-C3N4, resulting in high photocatalytic activity.","subitem_description_type":"Abstract"}]},"item_21_description_60":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Journal
