Phytopathogenic bacteria have been a prominent problem for the growth of plant and agricultural development. Iron-based oxygen generators will be environmental friendly materials for the treatment of phytopathogenic bacteria in hypoxia environment. To develop environmental friendly materials for bacterial treatment, a polymer fused iron(III) nano-complex (PPaba-FeEu@GO) was constructed. The PPaba-FeEu@GO was synthesized by polymerization of 4-aminobenzoic acid Fe(III) complex on the surface of 0.1 % Eu(III)-doped GO. This nano metal complex (PPaba-FeEu@GO) shows enhanced electron mobility and hole diffusion distance, hence it converts water into oxygen under LED light irradiation without adscititious cocatalyst. Moreover, PPaba-FeEu@GO can convert near-infrared light into heat. The photothermal conversion efficiency was calculated as 40.6 %. Therefore, PPaba-FeEu@GO is a light driven oxygen generator and bacterial inhibitor. Our results demonstrate that polymer fused metal-EuGO system will be kinds of reusable materials for bacterial treatment.

植物病原菌一直是植物生长和农业发展的突出问题。铁基氧气发生器将是低氧环境中治疗植物致病细菌的环保材料。为了开发用于细菌处理的环保材料，构建了聚合物熔铁（III）纳米复合物（PPaba-FeEu @ GO）。PPaba-FeEu @ GO是通过在0.1％Eu（III）掺杂的GO表面上聚合4-氨基苯甲酸Fe（III）配合物而合成的。这种纳米金属配合物（PPaba-FeEu @ GO）表现出增强的电子迁移率和空穴扩散距离，因此在LED光照射下将水转化为氧气而没有助催化剂。此外，PPaba-FeEu @ GO可以将近红外光转换为热量。计算出光热转化效率为40.6％。因此，PPaba-FeEu @ GO是一种光驱氧气发生器和细菌抑制剂。我们的结果表明，聚合物熔融金属-EuGO系统将是可重复使用的细菌处理材料。
