I have synthesized Nickle MOF using the microwave irradiation technique. However, I am unable to get the surface area of the material. What could be the possible reasons?
I have tried both mesoporous and microporous synthesis.
Hello,
Here are my suggestions:
First of all, characterizing your MOF by PXRD and indexing to know which phase your product is crystallized in. Is it porous or non-porous? An easy way to know your product is searching the fragments by using CCDC or scifinder or reaxys, which leads to your results quicker.
After ensuring your MOF is porous, please choose a way for activating your product (like solvent exchange, vacuum heating, SC-CO2, and so on), or find a supporting article that provide a route suitable for you.
Finally, for calculating BET surface area, there are multiple techniques to choose, like gas adsorption, dye adsorption, etc. The probing molecules can be varied depending on your material.
Wish you best of luck :)

Kevin Xiao Thanks for the reply.
I have done the XRD of the material which confirms that Ni MOF has been synthesized successfully. However, the porosity of the material is doubtful (not sure whether it is mesoporous or microporous, although literature reports it as mesoporous material ). Before BET analysis the material was degassed at 170 degrees celsius which assures the removal of DMF from the pores of the material. Still, on analysis, I am not getting significant results.
hello Garima Chaturvedi
It will be better if you find out a method that reported in the article and follow the procedure, i guess. After degassing, was your MOF still stable at that circumstance?
