Dependence of solvents, pH, molar ratio and . The main advantages of this method are that (1) organic solvents can be avoided, (2) room temperature is sufficient, (3) side products formed are harmless and (4) MOF can be obtained in short reaction time (Klimakow et al., 2010, Pilloni et al., 2015, Friščić, 2011, Yan et al., 2013, Singh et al., 2013). 2.6.
