Metal Organic Framework (MOF) molecules have been a focus of intense activity in recent years because of their extremely high porosity, tailorable cavity, and variety of applications such as hydrogen storage, selective adsorption and catalyst. However, all reported MOF syntheses so far were through a multiday of solvothermal approach. In this work, we present a new synthetic approach, named as “microwave assisted solvothermal synthesis” by us, which allows a series of MOFs to be synthesized in about one minute with uniform shape. We also demonstrate that crystal size can be varied from micrometer to nanometer simply by changing few reaction conditions. By this approach, MOF synthesis cycle can be largely shortened with controlled size and shape, which can be used from many practical applications.
