Using polystyrene (PS) microspheres as an auxiliary template, a kind of novel gully-like Sr-doped ZrO₂–TiO₂ composites with the heterogeneous structure were successfully prepared by a simple instant centrifugation with one-step hydrolysis method. The Sr-doped ZrO₂–TiO₂ composites consisted of the tetragonal phase ZrO₂, orthogonal phase SrZrO₃ and anatase phase TiO₂, showing a homogeneous concave and convex shape, similared to the naturally occurring gully terrain in nature, with a double-sized mesoporous structure. The SrZrO₃ was prepared by the synthetic method in this study, which provided a new reference for the subsequent synthesis of SrZrO₃. At the same time, Sr-doped ZrO₂–TiO₂ composites showed higher photocatalytic activity compared with the monomer and non-strontium-doped TiO₂-ZrO₂ under multi-mode photocatalytic conditions such as ultraviolet light, visible light, and simulated sunlight. The hydrogen production of Sr-doped ZrO₂–TiO₂ was 2.9 times and 4.4 times higher than that of TiO₂–ZrO₂ and TiO₂, indicating that Sr-doped played a synergistic role in photocatalytic activity experiments. Finally, by the capturing experiment of gully-like Sr-doped ZrO₂–TiO₂, it was confirmed that h⁺, ·OH, O₂^•− were active species in the photodegradation of malachite green, and the possible mechanism of the photocatalytic reaction was deduced.

以聚苯乙烯（PS）微球为辅助模板，通过一步水解简单瞬时离心，成功地制备了一种新型的异质结构沟状掺Sr的ZrO ₂ -TiO ₂复合材料。掺Sr的ZrO ₂ -TiO ₂复合材料由四方相ZrO ₂，正交相SrZrO ₃和锐钛矿相TiO _2组成，表现出均匀的凹凸形状，类似于自然界中的自然沟壑地形，并具有双介孔结构。SrZrO ₃本研究采用合成方法制备了SrZrO ₃，为后续的SrZrO ₃合成提供了新的参考。同时，在紫外线，可见光和模拟阳光等多模态光催化条件下，掺Sr的ZrO ₂ -TiO ₂复合材料比单体和非锶掺杂的TiO ₂ -ZrO ₂具有更高的光催化活性。。掺Sr的ZrO ₂ -TiO _2的产氢量比TiO ₂ -ZrO ₂和TiO _2的产氢分别高2.9倍和4.4倍。，表明Sr掺杂在光催化活性实验中起着协同作用。最后，通过沟状掺Sr的ZrO ₂ -TiO ₂的俘获实验，证实了h ⁺，·OH，O ₂ ^•－是孔雀石绿光降解中的活性物种，以及其光催化作用的可能机理。推断出反应。
