The rather high BET surface area (633.2 m2/g) and total pore volume (0.671 cm3 g−1) of the core–shell structure, make it promising for gas adsorption applications. The gas adsorption measurements were conducted for CO2, N2, H2, O2, CH4, C2H6, C3H8, C2H4, and C3H6 pure gases at ...
As a new material, metal organic framework has attracted wide attention due to its advantages of large specific surface area, adjustable pore size and abundant adsorption sites, and has been applied in the field of gas adsorption and liquid adsorption. ZIFs, as one of the metal organic ...
In contrast, in this work, the response surface method (RSM) was used to investigate the effect of various parameters and their interactions on crystallite size, synthesis yield, total pore volume, and BET surface area. These parameters included L/M, synthesis time, MeOH-DMF solvent composition...
