1甘氨酸在SiO_2表面的吸附及热缩合反应显示文摘考察了甘氨酸水溶液平衡浓度和pH值对其在SiO2 表面吸附行为的影响,采用DTG ,XRD和FT IR等手段对甘氨酸在SiO2 表面的吸附量及晶相结构等进行了表征.结果表明,甘氨酸在SiO2 上的吸附不符合Langmuir吸附模型,当甘氨酸水溶液平衡浓度小于0 0 73mol/L时,主要为特定位置吸附,此时SiO2 对甘氨酸的吸附源于其表面≡Si-O-基团与甘氨酸离子的-NH+3 端的相互作用;当平衡浓度大于0 0 73mol/L时,呈多层吸附,形成α和β两种晶型的甘氨酸.用TPD MS对甘氨酸的热缩合行为进行了考察,结合FT IR结果表明,产物为环状二聚体哌嗪二酮(DKP) ,没有检测到线式二聚体以及表面硅酯类物种形成.SiO2 对表面吸附的甘氨酸分子产生了诱导活化,使其热缩合温度与体相α甘氨酸相比降低了5 0℃左右.孟明 Lorenzo Stievano Jean-Franois Lambert 2005催化学报2005,26,5:7

18Mechanisms of electrochemical magnesium(de)alloying of Mg-Sn and Mg-Pb polymorphs显示文摘Different polymorphs of Mg-Sn and Mg-Pb intermetallic compounds were prepared by high-energy mechanical alloying and then investigated as active material in magnesium batteries. Beside thermodynamically stable Mg_(2)Sn and Mg_(2)Pb crystallizing in the anti-fluorite structure, other polymorphs Mg_(~2)Sn and Mg_(~2)Pb were prepared by increasing the ball-milling time. The first dealloying process is almost complete only for the cubic polymorphs, then similar capacities are observed during the subsequent alloying and dealloying sequences.Thanks to operando X-ray diffraction, the electrochemical mechanism is revealed and shows that the cubic polymorphs Mg_(2)Sn and Mg_(2)Pb tend to preferentially form during the alloying whatever the pristine intermetallic. Weak traces of Mg_(~2)Sn and Mg_(~2)Pb are observed during the alloying, suggesting that these polymorphs act as a by-product and/or an intermediate phases of the electrochemical process. Finally, the compatibility of cubic Mg_(2)Sn and Mg_(2)Pb with Mg(TFSI)_(2)-based electrolyte is confirmed in full cell vs. a positive electrode based on the Chevrel phase Mo6S8, although limited performance is achieved. This fundamental work provides new insights in the behavior of alloy-type negative electrodes for magnesium-ion batteries.Clément Pechberty Antoine Klein Bernard Fraisse Lorenzo Stievano Romain Berthelot 2022Journal of Magnesium and Alloys2022,10,6:0
19甘氨酸在无机氧化物表面吸附与热聚合机理研究显示文摘采用DTG、XRD、FTIR和in-situ DRIFT等手段对甘氨酸在SiO2和Al2O3表面的吸附和热聚合行为进行了研究.结果表明,在SiO2表面呈多层吸附,吸附量大,其聚合产物为环状二聚体DKP,SiO2对甘氨酸的吸附活化主要是通过表面≡Si-O-基团;而在Al2O3表面的吸附符合Langmuir吸附模型,吸附量小,吸附位主要是表面Lewis酸位(Al3+)和碱位(O2-),聚合产物为线式二聚体,高温下转化为环状二聚体DKP.孟明 L Stievano J F Lambert 2004石油化工2004,33,z1:0
