Photocatalysis is considered to be a promising technique for the degradation of organic pollutants. Herein, a 0D/1D composite photocatalyst consisting of Au nanoparticles (NPs) and CuBiO microrods (Au/CBO) was designed and prepared by a simple thermal reduction-precipitation approach. It shows excellent photocatalytic performance in the degradation of tetracycline (TC). The maximum photocatalytic degradation rate constant for Au/CBO composites with 2.5 wt % Au NPs was 4.76 times as high as that of bare CBO microrods. Additionally, the 0D/1D Au/CBO composite also exhibited ideal stability. The significant improvement of the photocatalytic performance could be attributed to the improved light harvesting and increased specific surface area, enhancing photoresponse and providing more active sites. Our work shows a possible design of efficient photocatalysts for environmental remediation.
光催化被认为是一种用于降解有机污染物的很有前景的技术。在此，通过一种简单的热还原沉淀法设计并制备了一种由金纳米颗粒（NPs）和CuBiO微棒组成的0D/1D复合光催化剂（Au/CBO）。它在四环素（TC）的降解中表现出优异的光催化性能。含2.5 wt%金纳米颗粒的Au/CBO复合材料的最大光催化降解速率常数是裸CBO微棒的4.76倍。此外，0D/1D Au/CBO复合材料还表现出理想的稳定性。光催化性能的显著提高可归因于光捕获的改善和比表面积的增加，增强了光响应并提供了更多的活性位点。我们的工作展示了一种用于环境修复的高效光催化剂的可能设计。
