Abstract 

We have developed a microdroplet-based nanomanufacturing process to fabricate nanomaterials based on Metal organic frameworks (MOFs). the process is rapid, continuous, and scalable ,and the nanomaterials have controlled hierarchical nanostructures. We investigated the mechanisms of rapid formation of MOFs inside the microdroplets by both experimental and theoretical approaches. We also developed several strategies to integrate MOFs with semiconductors to form hybrid nanocomposites for various environmental applications, such as the adsorption and  photoreduction of carbon dioxide and detection of formaldehyde. We also explored the quantitative mechanisms of gas adsorption, activation, and charge transfer within the hybrid nanostructures by various in situ techniques, such as diffuse reflectance infrared Fourier transform spectroscopy, photoluminescence spectroscopy, and x-ray photoelectron spectroscopy.
