| 似乎水滑石類的催化劑都很難合成啊,有人合成過鎂鋁水滑石嗎?這方面有什么經(jīng)典的方法或文獻? |

鎂鋁水滑石確實是最好做的,兩種元素價態(tài)都定下來了,沒有變價,而且兩種元素比例范圍也很大,直接去知網(wǎng)上面搜碩博論文就行了,不需要太高端的文獻……難做的是變價金屬的水滑石,我之前做鈷錳的水滑石,第一次就失敗了,時隔一年之后,參考JACS上一篇文獻才合成出來 發(fā)自小木蟲Android客戶端 |

In fact, it is easy to prepare. You can use double titration or single titration. The literatures are listed as follow: 1. Mechanism of reconstitution of hydrotalcite leading to eggshell-type Ni loading on MgAl mixed oxide Journal of Catalysis, Volume 231, Issue 1, 1 April 2005, Pages 92-104 Katsuomi Takehira, Tomonori Kawabata, Tetsuya Shishido, Kazuhiro Murakami, Takenori Ohi, Daisuke Shoro, Masahide Honda, Ken Takaki 2. High activity of Mn-MgAl hydrotalcite in heterogeneously catalyzed liquid-phase selective oxidation of alkylaromatics to benzylic ketones with 1 atm of molecular oxygen Journal of Catalysis, Volume 247, Issue 2, 25 April 2007, Pages 214-222 Suman K. Jana, Yoshihiro Kubota, Takashi Tatsumi 3. NiAl hydrotalcite as an efficient and environmentally friendly solid catalyst for solvent-free liquid-phase selective oxidation of ethylbenzene to acetophenone with 1 atm of molecular oxygen Journal of Catalysis, Volume 240, Issue 2, 10 June 2006, Pages 268-274 Suman K. Jana, Peng Wu, Takashi Tatsumi 4. Cobalt-substituted polyoxometalate pillared hydrotalcite: Synthesis and catalysis in liquid-phase oxidation of cyclohexanol with molecular oxygen Journal of Catalysis, Volume 255, Issue 1, 1 April 2008, Pages 40-47 Suman K. Jana, Yoshihiro Kubota, Takashi Tatsumi 5. exchanged Mg–Al hydrotalcite: a stable and reusable/environmental-friendly catalyst for selective oxidation by oxygen of ethylbenzene to acetophenone and diphenylmethane to benzophenone Journal of Catalysis, Volume 227, Issue 1, 1 October 2004, Pages 257-261 Vasant R. Choudhary, Jayant R. Indurkar, Vijay S. Narkhede, Rani Jha 6. Catalytic performance and mechanism of potassium-promoted Mg–Al hydrotalcite mixed oxides for soot combustion with O2 Journal of Catalysis, Volume 271, Issue 1, 12 April 2010, Pages 12-21 Zhaoliang Zhang, Yexin Zhang, Zhongpeng Wang, Xiyan Gao |
