Herein, we reported the systematic investigation of synergistic photo-thermal-catalysis for NaBH₄ hydrolysis reaction based on zinc orthogermanate. A series of Zn₂GeO₄:xFe³⁺ (x = 0 to 0.10) catalysts were prepared via solvothermal method. The H₂ evolution experiments demonstrated that the photogenerated holes trap OH⁻ not only shifted the equilibrium of NaBH₄ hydrolysis reaction toward the direction of H₂ evolution, but also inhibited the recombination of photogenerated carriers. With the remarkable photo-thermal synergism for the as-prepared catalysts, the H₂ evolution rate in photo-thermal-driven condition had witnessed several times higher than that in mono-energy driven condition. The catalysts remained stable after circulation tests.

在这里，我们报道了基于高锗酸锌协同光热催化NaBH ₄水解反应的系统研究。 通过溶剂热法制备了一系列的Zn ₂ GeO ₄：x Fe ³⁺（x = 0至0.10）催化剂。为H ₂进化实验表明，光生空穴陷阱OH ^-不仅移的NaBH的平衡₄朝向H方向水解反应₂进化，但也能抑制光生载流子的复合。对于所制备的催化剂，H ₂具有显着的光热协同作用光热驱动条件下的演化速率是单能量驱动条件下的几倍。循环测试后，催化剂保持稳定。
