| 3 | N-doped CoAl oxides from hydrotalcites with enhanced oxygen vacancies for excellent low-temperature propane oxidation显示文摘A series of nitrogen-doped CoAlO(N-CoAlO)were constructed by a hydrothermal route combined with a controllable NH_(3) treatment strategy.The effects of NH_(3) treatment on the physico-chemical properties and oxidation activities of N-Co AlO catalysts were investigated.In comparison to CoAlO,a smallest content decrease in surface Co^(3+)(serving as active sites)while a largest increased amount of surface Co^(2+)(contributing to oxygen species)are obtained over N-Co AlO/4h among the N-CoAlO catalysts.Meanwhile,a maximum N doping is found over N-CoAlO/4h.As a result,N-CoAlO/4h(under NH_(3) treatment at 400℃ for 4 hr)with rich oxygen vacancies shows optimal catalytic activity,with a T90(the temperature required to reach a 90% conversion of propane)at 266℃.The more oxygen vacancies are caused by the co-operative effects of N doping and suitable reduction of Co^(3+) for NCoAlO/4h,leading to an enhanced oxygen mobility,which in turn promotes C_(3)H_(8) total oxidation activity dominated by Langmuir-Hinshelwood mechanism.Moreover,in situ diffuse reflectance infrared Fourier transform spectroscopy(DRIFTs)analysis shows that N doping facilities the decomposition of intermediate species(propylene and formate)into CO_(2)over the catalyst surface of N-CoAlO/4h more easily.Our reported design in this work will provide a promising way to develop abundant oxygen vacancies of Co-based catalysts derived from hydrotalcites by a simple NH_(3) treatment. | Enhui Wu Daifeng Lin Yinye Chen Xiaoshan Feng Kui Niu Yongjin Luo Baoquan Huang Jianbin Qiu Qingrong Qian Qinghua Chen | 2022 | Journal of Environmental Sciences2022，34，6： | 0 |
| 4 | Insights into the Low-temperature Synthesis of LaCoO3 Derived from Co(CH3COO)2 Via Electrospinning for Catalytic Propane Oxidation显示文摘Summary of main observation and conclusion A series of electrospun LaCoO3 perovskites derived from CoX2 (X =CH3COO-,NO3-) were prepared and investigated for total propane oxidation.It is shown that pure rhombohedral perovskite LaCoO3 from Co(CH3COO)2 can be obtained at a relatively low temperature,400 ℃,benefitting from the complexation effect of CH3COO-.On the other hand,CH3COO-can accelerate the complete decomposition of polymer.The low-temperature process can protect LaCoO3 nanoparticles from growing up. | Yingbin Zheng Xiaoshan Feng Daifeng Lin Enhui Wu Yongjin Luo Yufeng You Baoquan Huang Qingrong Qian Qinghua Chen | 2020 | Chinese Journal of Chemistry2020，38，2： | 0 |
