Abstract Metal organic frameworks (MOFs) are an exciting class of highly porous polymer crystals with superior surface areas, tunable porosities, and rich functionality, enabling them for a variety of applications in energy and environmental sectors. We have developed aerosol-based synthetic strategies to integrate MOFs with semiconductors to form hybrid nanocomposites for various environmental applications, such as CO2 adsorption and photoreduction. With increased charge carrier density and efficient CO2 activation, the hybrid ternary nanocomposite exhibits a high CO2 conversion efficiency and preferential formation of CH4. Systematic measurements by using gas chromatography, photoluminescence spectroscopy, X-ray photoelectron spectroscopy, and time-resolved in-situ diffuse reflectance infrared Fourier transform spectroscopy reveal that the semiconductor heterojunction and the coordinatively unsaturated copper sites within the hybrid nanostructure are attributable to the performance enhancements.
