  • With zinc acetate and urea as raw materials, the porous single crystalline ZnO nanoplates were prepared by hydrothermal method combined with the heat treatment process.The Au nanoparticles were synthesized by the citric acid reduction method.Then, polyethylenimine (PEI) was used to modify the porous single crystalline ZnO nanoplates followed by anchoring Au nanoparticles (NPs) on their surface through electrostatic interactions.The as-prepared products were characterized by X-ray diffraction (XRD),scanning electron microscopy (FE-SEM) and energy dispersive spectrum (EDS).The porous ZnO nanostructures and the successful modification of Au nanoparticles were observed.The gas sensitivity experiment showed the as-prepared products exhibited the remarkable selectivity to formaldehyde,the best working temperature was 300℃ and a favorable linear response range was 10~500×10-6.
