The polymer fused iron(III) nano-complex, PPaba-FeEu@GO, has been developed as an environmentally friendly material for treating phytopathogenic bacteria in hypoxia environments. This nano metal complex shows enhanced electron mobility and hole diffusion distance, converting water into oxygen under LED light irradiation without additional co-catalyst, and can also convert near-infrared light into heat.
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, PPabaFeEu@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.
