Development of novel solid-solution photocatalysts for environmental remediation under visible light irradiation

我们的日常生活暴露于多种有害化合物，如VOC（挥发性有机化合物）。为了我们的安全生活，清除这些有害化合物是很重要的。光催化技术被认为是解决这些问题的一种潜在方法。然而，由于已经开发的光催化剂对可见光不敏感，目前光催化技术很难用于室内应用。因此，在本研究中，我们试图找到新的可见光敏感的光催化剂，其带隙控制的固溶体的制备。因此，我们成功地开发了新型可见光敏感的光催化剂，并找到了开发高活性材料的新方法。

Our dairy life is exposed to many kinds of harmful compounds, such as VOCs (volatile organic compounds). For our safe life, it is important to remove these harmful compounds. Photocatalytic technology is regarded as a potential method for solving these problems. However, since the photocatalysts which have already developed are not sensitive to visible light, the photocatalytic technology is difficult to be utilized for indoor application, at present. Therefore, in this study we tried to find novel visible light sensitive photocatalysts, of which band gaps were controlled by preparation of solid solutions. As a result, we succeeded in developing of novel visible light sensitive photocatalysts and finding novel methods for development of high active materials.
