1Ni/Al_2O_3 catalysts for CO methanation: Effect of Al_2O_3 supports calcined at different temperatures显示文摘The correlation between phase structures and surface acidity of Al2O3 supports calcined at different temperatures and the catalytic performance of Ni/Al2O3 catalysts in the production of synthetic natural gas(SNG) via CO methanation was systematically investigated. A series of 10 wt% NiO/Al2O3 catalysts were prepared by the conventional impregnation method, and the phase structures and surface acidity of Al2O3 supports were adjusted by calcining the commercial γ-Al2O3 at different temperatures(600–1200 C). CO methanation reaction was carried out in the temperature range of 300–600 C at different weight hourly space velocities(WHSV = 30000 and 120000 mL·g-1h-1) and pressures(0.1 and 3.0 MPa). It was found that high calcination temperature not only led to the growth in Ni particle size, but also weakened the interaction between Ni nanoparticles and Al2O3 supports due to the rapid decrease of the specific surface area and acidity of Al2O3 supports. Interestingly, Ni catalysts supported on Al2O3 calcined at 1200 C(Ni/Al2O3-1200) exhibited the best catalytic activity for CO methanation under different reaction conditions. Lifetime reaction tests also indicated that Ni/Al2O3-1200 was the most active and stable catalyst compared with the other three catalysts, whose supports were calcined at lower temperatures(600, 800 and 1000 C). These findings would therefore be helpful to develop Ni/Al2O3 methanation catalyst for SNG production.Jiajian Gao Chunmiao Jia Jing Li Meiju Zhang Fangna Gu Guangwen Xu Ziyi Zhong Fabing Su 2013Journal of Energy Chemistry2013,22,6:16

4各向异性金纳米粒子的制备及其在催化中的应用(英文)显示文摘尽管有关金纳米粒子催化的研究工作很多,但其中大多数都是采用传统的浸渍法将金盐负载到载体上、共沉淀或沉积-沉淀法制得负载的纳米粒子,但这些方法并未吸收最新的纳米技术.最近,金催化剂的研究者开发了在胶态悬浮液中制取金属纳米粒子,然后进行固载,从而使得单金属和双金属催化剂的催化活性和形貌控制取得较大进展.另一方面,最近十年出现了金纳米粒子合成的高级控制技术,得到了许多各向异性的金纳米粒子,且很容易制得新的形貌,可以控制纳米粒子的表面原子配位数和光学特性(可调的等离子体带),这些都与催化密切相关.这些形貌包括纳米棒、纳米星、纳米花、树枝状纳米结构或多面体纳米粒子等.除了高度关注各向异性金纳米粒子的最新开发的制备方法和性质,本综述也清楚地总结了这些纳米粒子独特的催化性能,以及通过提供更高催化性能的金催化剂、控制暴露的活性位,以及热、电和光催化的鲁棒性和可调性,从而给多相催化领域带来令人惊奇的潜在变革.Peter Priecel Hammed Adekunle Salami Romen Herrera Padilla Ziyi Zhong Jose Antonio Lopez-Sanchez 2016Chinese Journal of Catalysis2016,37,10:5

9Single-atom Sn-Zn pairs in CuO catalyst promote dimethyldichlorosilane synthesis显示文摘Single-atom catalysts are of great interest because they can maximize the atom-utilization efficiency and generate unique catalytic properties;however,much attention has been paid to single-site active components,rarely to catalyst promoters.Promoters can significantly affect the activity and selectivity of a catalyst,even at their low concentrations in catalysts.In this work,we designed and synthesized CuO catalysts with atomically dispersed co-promoters of Sn and Zn.When used as the catalyst in the Rochow reaction for the synthesis of dimethyldichlorosilane,this catalyst exhibited much-enhanced activity,selectivity and stability compared with the conventional CuO catalysts with promoters in the form of nanoparticles.Density functional theory calculations demonstrate that single-atomic Sn substitution in the CuO surface can enrich surface Cu vacancies and promote dispersion of Zn to its atomic levels.Sn and Zn single sites as the co-promoters cooperatively generate electronic interaction with the CuO support,which further facilitates the adsorption of the reactant molecules on the surface,thereby leading to the superior catalytic performance.Qi Shi Yongjun Ji Wenxin Chen Yongxia Zhu Jing Li Hezhi Liu Zhi Li Shubo Tian Ligen Wang Ziyi Zhong Limin Wang Jianmin Ma Yadong Li Fabing Su 2020National Science Review2020,7,3:2

11Ordered mesoporous Cu-Ca-Zr:A superior catalyst for direct synthesis of methyl formate from syngas显示文摘It is still a big challenge to obtain both highly active and stable Cu-based catalysts for direct synthesis of methyl formate(MF)from syngas.To address the issue,we have designed and synthesized a series of ternary Cu-Ca-Zr catalysts,namely,the ordered mesoporous Cu-Ca-Zr catalyst prepared by one-pot evaporation-induced self-assembly(EISA)method,and the supported CuO/CaO-ZrO_(2)catalysts by impregnating with copper precursor or by immobilizing copper nanoparticles.In the latter two catalysts,the ordered mesoporous CaO-ZrO_(2)support was also prepared by the EISA method.The catalysts were characterized by techniques such as ICP,XRD,TEM,N2 isotherm adsorption-desorption,XPS and H2-TPR,and used for direct synthesis of MF.The results indicated that the catalyst prepared by onepot EISA method,in which the CuO species are highly dispersed in frame of CaO-ZrO_(2),exhibits much better activity and stability as compared with the other two catalysts with most of CuO located on the outer surface of the CaO-ZrO_(2)support,because the former has a higher specific surface area,enhanced synergistic effect and stronger interaction between the CaO-ZrO_(2)support and CuO active constituent.Jiahao Zhuang Bin Lu Fangna Gu Ziyi Zhong Fabing Su 2018Carbon Resources Conversion2018,1,2:2
12Molecular catalysis for the steam reforming of ethanol显示文摘In this paper,the application of molecular catalysis for steam reforming of ethanol(SRE)is reviewed.Eight metals(Ni,Co,Cu,Pt,Rh,Pd,Ir and Ru)have shown high catalytic activity for SRE.Among them Ni and Rh are very promising because of high d character in the metal bond and low metal-oxygen bonding(vs.metal-carbon).They can effectively promote C–C bond cleavage in the rate-determining process during SRE.However,Rh is weak in water-gas-shift so that CH4 and CO become the main by-products at low reaction temperatures,while Ni catalysts suffer from rapid deactivation due to coking and sintering.Two low-temperature CO-free catalysts have been developed in our lab,namely Rh-Fe/Ca-Al2O3 and carbonyl-derived Rh-Co/Ce O2,in which the presence of iron oxide or Co can promote water-gas-shift reaction and significantly improve the SRE performance.On the other hand,adding 3 wt%Ca O to Ni/Al2O3 can greatly improve the catalyst stability because the Ca modification not only increases Ni concentration on the Ni/Ca-Al2O3 surface and 3d valence electron density,but also facilitates the water adsorption and coke gasification via water-gas-shift.The availability of abundant surface OH groups helps the formation and conversion of adsorbed formate intermediate.Hence,ethanol reaction on Ca-Al2O3-supported Ni,Pt,Pd and Rh catalysts are found to follow the formate-intermediated pathway,a new reaction pathway alternative to the traditional acetate-intermediated pathway.Jianyi Lin Luwei Chen Catherine Kai Shin Choong Ziyi Zhong Lin Huang 2015Science China Chemistry2015,58,1:1

18Efficacy and safety of Sancai powder in patients with type 2 diabetes mellitus: a randomized controlled trial显示文摘OBJECTIVE: To assess the efficacy and safety of Sancai powder in patients with type 2 diabetes mellitus(T2DM) inadequately controlled with single oral metformin in a randomized controlled trial(RCT).METHODS: A total of 132 patients with T2 DM were enrolled in the study, who only took metformin(500-1000 mg/day) for at least three months and with inadequate glycemic control(7.0% ≤ hemoglobin A1 c ≤ 9.0%) in the past three months.The patients stopped taking metformin with lifestyle interventions for three weeks, and 105 patients qualified for the program. They were randomly divided into the Sancai powder group and the metformin group(1500 mg/day). The follow-up period was for 12 weeks. Comparisons of several variables were analyzed.RESULTS: No significant differences were found between the two groups in hemoglobin A1c(Hb A1c),fasting plasma glucose(FPG) and 2 h post-meal glucose(2h PG), although they had decreased significantly(P < 0.01). Homeostasis model assessment of beta cell function index was significantly improved in Sancai powder group(P < 0.01), and there were significant differences in the changes of homeostasis model assessment of insulin resistance and insulin sensitivity index in the two groups(P < 0.05). Sancai powder significantly reduced triglyceride level(P < 0.05), although there was no significant difference in the body weight and body mass index in the two groups.CONCLUSION: In this 12-week study, Sancai powder could significantly reduce hemoglobin A1 c,FPG and 2h PG levels, improved beta-cell function and insulin resistance of the T2 DM inadequately controlled with metformin.Guo Qiang Zhang Hengyao Li Mindian Zhao Ziyi Luo Yunlin Luo Yulei Cao Wenzhai Zhao Huan Zhu Ranran Lei Xingxing Chen Huizhen Gan Huakui Zuo Zhihuang Chen Qi Shi Cuimei Zhang Xinli Guo Jian Zhong Sen Chen Qiu 2016Journal of Traditional Chinese Medicine2016,36,5:1
