文獻(xiàn)中說的是0.15g五水硝酸鉍和0.75g H3BTC溶于60mL甲醇然后放入反應(yīng)釜120度24小時(shí)。但是問題是硝酸鉍放入甲醇超聲會(huì)立馬水解產(chǎn)生白色沉淀。請(qǐng)問有大神知道如何解決嗎?感謝感謝! 發(fā)自小木蟲Android客戶端 |

多看幾個(gè)文獻(xiàn)吧,我看到的這個(gè)文獻(xiàn)沒有超聲 Synthesis of CAU-17 All chemicals were purchased and obtained from Aldrich, Alfa Aesar, or BASF. They were used without further purification. Synthesis was carried out under solvothermal conditions in a Biotage Initiator microwave oven with 10 mL vials. Suitable single crystals were obtained by mixing H3BTC (62.5 mg, 297 μmol) and ground Bi(NO3)3·5H2O (125.5 mg, 259 μmol) with 5 mL of MeOH at room temperature. The sealed glass vial was shaken by hand for 1 min and subsequently heated in the microwave oven to 120 °C for 20 min with 600 rpm stirring. The obtained colorless single crystals were collected by filtration. X-ray powder diffraction was performed to confirm the purity of the sample 文獻(xiàn)來源 J. Am. Chem. Soc. 2016, 138, 1970−1976 |
