In this work, we suggested that an efficient ZnO-based photocatalyst can be prepared utilizing energy transfer among organic dyes for visible light-driven hydrogen evolution. Followed this idea, a photocatalytic system containing Eosin Y, Rose Bengal, ZnO nanorod array and Pt was fabricated. Meanwhile, photocatalytic H₂ evolution over the as-prepared photocatalytic system was explored. The results indicate that the visible photocatalytic activity of ZnO nanorod array can be obviously enhanced utilizing the energy transfer between Eosin Y and Rose Bengal. This photocatalytic system possesses high activity for visible light-driven H₂ evolution. A rate of H₂ evolution of approximate 0.52 L m⁻² h⁻¹ was achieved under optimal condition, which is 130% and 58% higher than those of the photocatalytic systems containing individual dye, respectively. The present results may reveal a new strategy for preparation of efficient visible photocatalyst.

在这项工作中，我们建议可以利用有机染料之间的能量转移来制备有效的基于ZnO的光催化剂，用于可见光驱动的氢气释放。遵循此想法，制造了包含曙红Y，孟加拉红，ZnO纳米棒阵列和Pt的光催化系统。同时，探索了在所制备的光催化体系上光催化H _2的逸出。结果表明，利用曙红Y和玫瑰红之间的能量转移，可以明显提高ZnO纳米棒阵列的可见光催化活性。该光催化系统对于可见光驱动的H ₂析出具有很高的活性。H ₂的释放速率约为0.52 L m ^-2  h ^-1在最佳条件下获得了最佳光催化效果，分别比包含单个染料的光催化体系高出130％和58％。目前的结果可能揭示了一种制备高效可见光催化剂的新策略。
