Two appealing alternatives for MOFs synthesis: solvent-free oven heating vs. microwave heating

Abstract

Herein we present a solvent-free process to afford the synthesis of imidazolate and carboxylate based MOFs performed under moderate oven-heating or fast microwave irradiation, paying special attention to the yield and adsorption performance of the products. The measured adsorption surface area values of the resulting samples compare well, and in several cases surpass, the maximum surface area previously reported for the same compounds prepared using a solvent based synthesis.
