Ni-MOF/Zn0.5Cd0.5S合成及其光催化废水制氢研究
Synthesis of Ni-MOF/Zn0.5Cd0.5S and the photocatalytic hydrogen production performance from wastewater
摘要
Abstract
In order to enhance the photocatalytic hydrogen production performance of Zn0.5Cd0.5S,Ni-MOF modified Zn0.5Cd0.5S composite photocatalyst was prepared by hydrothermal method.The structure and photoelectrochemical properties of the prepared samples were characterized by XRD,SEM,TEM,XPS and other analytical methods.The results show that Zn0.5Cd0.5S mainly presents a nano particle structure,and Ni-MOF is mainly composed of ultra-thin square sheets with a length of about 10 μm and a width of about 9 μm.When Ni-MOF is combined with Zn0.5Cd0.5S,the Zn0.5Cd0.5S nanoparticles deposit on the surface of the Ni-MOF square sheet,and the particle size is significantly reduced,reducing the aggregation of Zn0.5Cd0.5S nanoparticles.In addition,there is a blue shift in the light absorption range for the composite,but still excellent visible light response ability.In the landfill leachate mixed shale gas flowback wastewater,the 15％Ni-MOF/Zn0.5Cd05S shows the best photocatalytic hydrogen production performance.Under simulated sunlight,the hydrogen production after 3 h of illumination is up to 1887 μmol.The hydrogen production process satisfies the zero-level reaction,with a hydrogen production rate of 685.9 μmol/h,which is approximately 5.7 times as high as the hydrogen production rate of Zn0.5Cd0.5S.关键词
