1Catalytic activities and mechanism of formaldehyde oxidation over gold supported on MnO2 microsphere catalysts at room temperature显示文摘有各种各样的表面结构的 MnO 2 microspheres 用热水的方法被准备,并且 Au/MnO 2 催化剂用大音阶的第五音胶化方法被综合。我们获得了三件 MnO 2 microspheres 和 Au/MnO 2 样品:与 nanoplatelets 和 nanorods 被像电线的 nanostructures,有 nanosheets 的稳固的范围,和层次空 microspheres 盖住的协调稳固的范围。我们在房间温度调查了性质和甲醛氧化的催化活动。MnO 2 的水晶的结构是影响这些样品的催化活动的主要因素,并且 -MnO2 显示出高催化的性能。优秀氧化还原作用性质为 -MnO2 的催化能力负责。支持黄金的相互作用能改变催化剂的氧化还原作用性质并且加速表面氧种类转变,它能说明 Au/MnO 2 的催化活动改进。我们也学习了中间的种类。dioxymethylene (DOM ) 和在催化剂表面上形成的甲酸盐种类被认为中介,并且最终被转变成 hydrocarbonate 和碳酸盐然后把 2 分解了成公司。在 Au/MnO 2 催化剂上的甲醛氧化的建议机制也被获得。Guanglong PANG Donghui WANG Yunhong ZHANG Chunyan MA Zhengping HAO 2016Frontiers of Environmental Science & Engineering2016,10,3:5
2Layered sphere-shaped TiO_2 capped with gold nanoparticles on structural defects and their catalysis of formaldehyde oxidation显示文摘We describe here a one-step method for the synthesis of Au/TiO_2 nanosphere materials,which were formed by layered deposition of multiple anatase TiO_2 nanosheets.The Au nanoparticles were stabilized by structural defects in each TiO_2 nanosheet,including crystal steps and edges,thereby fixing the Au-TiO_2 perimeter interface.Reactant transfer occurred along the gaps between these TiO_2 nanosheet layers and in contact with catalytically active sites at the Au-TiO_2 interface.The doped Au induced the formation of oxygen vacancies in the Au-TiO_2 interface.Such vacancies are essential for generating active oxygen species(~*O^-) on the TiO_2 surface and Ti^(3+) ions in bulk TiO_2.These ions can then form Ti^(3+)-O^--Ti^(4+)species,which are known to enhance the catalytic activity of formaldehyde(HCHO) oxidation.These studies on structural and oxygen vacancy defects in Au/TiO_2 samples provide a theoretical foundation for the catalytic mechanism of HCHO oxidation on oxide-supported Au materials.Chunyan Ma Guanglong Pang Guangzhi He Yang Li Chi He Zhengping Hao 2016Journal of Environmental Sciences2016,28,1:1
