Creating inverse opal structures! Here we introduce examples that enhance photocatalytic capabilities.
An example of creating a two-layer TiO2/BiVO4 framework with an inverse opal structure to enhance photocatalytic ability. It has been confirmed that the photocatalytic ability increased by 8.5 times and 2.2 times compared to single-layer and single-film inverse opal structures, respectively. The high periodicity of the inverse opal structure allows for light absorption and exhibits high photocatalytic activity, but it traps slow photons within a narrow wavelength range. Therefore, the usable wavelengths are limited. To overcome this, a two-layer TiO2/BiVO4 inverse opal structure with different pore sizes was created to form two photonic band gaps, enabling the capture of slow photons. *For more detailed information, please refer to the related links.

The advent of nanoscale materials has made it possible for materials science to have direct connections with biology, optics, and other fields. Photonic crystals and structural colors found in birds and insects are good examples of this. Until now, we have worked with various materials such as semiconductors, carbon materials, metals, oxides, and polymers. Leveraging this experience, we hope to be able to assist you in solving your "problems."
