In this work, the enhanced charge transfer in CaTiO₃/Pr³⁺-Y₂SiO₅/RGO catalyst was achieved by assembled RGO with CaTiO₃ and Pr³⁺-Y₂SiO₅ in visible light driven water splitting. By taking advantage of upconversion luminescence material Pr³⁺-Y₂SiO₅ (Pr³⁺-YSO), visible light was upconverted into UV light and was used to excite UV responded nano-CaTiO₃ to form charge pairs. Then the efficient forward charge transfer to hydrogen generation site Pt was fulfilled over RGO. Longer life time of charges was confirmed by fluorescence spectra in this catalyst. Simultaneously, removing nascent formed oxygen from reaction mixture by an artificial gill significantly inhibited hydrogen–oxygen reverse recombination reaction. By those technologies application, visible-light-driven overall water splitting was accomplished. The photocatalytic activity for hydrogen generation has been raised up to 480% with excellent stability in three recycle reactions. This photocatalyst system is efficient for visible overall split water over UV-responsive photocatalysts.

在这项工作中，在可见光驱动的水分解中，通过将RGO与CaTiO ₃和Pr ³⁺ -Y ₂ SiO ₅组装在一起，可以实现CaTiO ₃ / Pr ³⁺ -Y ₂ SiO ₅ / RGO催化剂中电荷转移的增强。通过利用上转换发光材料Pr ³⁺ -Y ₂ SiO ₅（Pr ³⁺ -YSO），可见光被上转换为紫外线，并用于激发紫外线响应的纳米CaTiO _3。形成电荷对。然后通过RGO实现了高效的正向电荷转移至氢生成位点Pt。通过该催化剂的荧光光谱确认了电荷的更长寿命。同时，通过人工g从反应混合物中除去新生的形成的氧气，显着抑制了氢氧反向重组反应。通过这些技术的应用，完成了可见光驱动的总水分解。在三个循环反应中，具有优异的稳定性，氢气的光催化活性已提高到480％。该光催化剂体系对于可见的总分解水比对紫外线敏感的光催化剂有效。
