First, 5.70 g of Zn(NO3)2·6H2O (Aladdin, AR) and 4.73 g of 2-methylimidazole (Aladdin, AR) were dissolved in 45 mL methanol (Sinopharm, AR) one after another to make a high concentration of the reactant solution. Then, around 4 g of washed polystyrene template was soaked in the above-mentioned reactant solution for 1 h and then placed under a negative pressure of −0.8 MPa for 10 min to guarantee as much reactant immersing into the void of polystyrene templates as possible. The treated templates were taken out and dried at 60 °C overnight (denoted as preZIF-8@Fcc-PS). Furthermore, preZIF-8@Fcc-PS were soaked in 60 mL of methanol and ammonia (Sinopharm, AR, 25–28%) mixed solvent (1 : 1 ratio, by volume) under −0.6 MPa for 3 min before the mixture stood at normal temperature and pressure for 24 h. At this stage, preZIF-8@Fcc-PS would split into pieces resulting from the crystallization force. Subsequently, the mixed solvent was poured away and the obtained fragments were dried for several hours (ZIF-8@Fcc-PS). At last, ZIF-8@Fcc-PS was immersed into dimethyl formamide (DMF, Sinopharm, AR) for 24 h to remove the polystyrene sphere templates, and this process was repeated 5 times in order to wash completely.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
