Efficient tuning: The photocatalytic activity of SrTiO₃ depends strongly on the donor density, which can be modified by Mg incorporation. After decreasing the donor density and modification with suitable co-catalysts, the water-splitting activity of Mg-modified SrTiO_x is found to be 20 times higher than of SrTiO₃.

通过控制镁掺入SrTiO3光催化剂促进光催化总水分解

高效调谐：SrTiO ₃的光催化活性在很大程度上取决于供体密度，该密度可以通过掺入Mg来改变。在降低供体密度并用合适的助催化剂改性后，发现Mg改性SrTiO _x的水分解活性比SrTiO ₃高20倍。
