“…several days for hydrothermal and solvothermal methods, or several weeks for diffusion method) and have to be performed at high reaction temperature (usually 373-523 K) and pressure (1-10 MPa) in many cases. Recently, a highly efficient route to MOFs has been developed through a microwave assisted hydrothermal method, but the reaction is still carried out at high reaction temperature and pressure [8,9]. Furthermore, compared with the rapid developments and numerous studies on their applications in selective adsorption, molecular exchange and separation, especially the latest howling successes in hydrogen storage [10][11][12], application of MOFs in sensor technology remains largely unexplored [13,14].…”
