Analog structure
Product traits
Product appearance, white powder
Off-white Powder
Particle size 2-3 um; irregular
stability
1) Stable in the air, stable for several days in an aqueous solution, decomposed in an acidic solution
2) Moisture molecules in the structure will lose water at 130°C under heating, and the remaining skeleton structure will gradually decompose after it exceeds 450°C
Preservation and activation methods
1) Store in a dry and airtight condition at room temperature or low temperature
2) If activation is required, activate in a 70 degree (vacuum) oven for 2 hours
Other features
Fluorescence: NA
Application field
1) ZIF-7 can be applied to the adsorption and separation of hydrogen and the adsorption and separation of ethane/ethylene
2) ZIF-7 has a high carbon content and can be carbonized at high temperature to obtain a porous carbon material with a certain morphology for gas adsorption
