We focused on iron oxide nanotube arrays (FNA) and graphitic carbon nitride (g-C₃N₄) among photocatalyst. And, we have been working toward the structural control of the composite by the thermochemical vapor deposition (CVD) method and the enhancement of its photocatalytic activity. As a result, we confirmed that the measurements of absorbance changes upon nitroblue tetrazolium (NBT) reduction showed that the absorbance reduction rate of the FNA/g-C₃N₄ sample exceeded that of the FNA and g-C₃N₄ samples. Presumably because the Z-scheme was formed at the FNA/g-C₃N₄ interface.
