Control of atmospheric CO2 emission has become a central issue worldwide due to its potential impact on global climate change. Capturing CO2 and converting it into chemicals, materials, and fuels using renewable energy, is an important path for sustainable development. The fossil fuels that make up over 80% of the global primary energy supply today all originated from CO2 millions of years ago. As a new direction of sustainable energy development, capture and catalytic conversion of CO2 can be used for production of carbon-based chemicals and fuels as well as materials which are currently produced using fossil energy. This presentation will discuss some new design approaches to CO2 capture and catalytic CO2 conversion to chemicals and fuels. One of the new approaches for CO2 capture is based on solid “Molecular Basket” sorbent (MBS) being developed at the Pennsylvania State University. MBS consists of functional polymers and nano-porous materials which shows high selectivity to CO2 at high capacity. MBS has been successfully demonstrated for CO2 capture and separation at pilot plant scale. The structures of the nano-porous materials and the functional polymers are major factors affecting the working capacity, rates of uptake and release of CO2, and stability. Due to its low reactivity as the product of combustion, CO2 activation and conversion are challenging tasks. We have been exploring various new bimetallic catalysts and multi-functional catalysts for the activation and hydrogenation of CO2, using H2 produced from H2O with renewable energy. Various catalysts and processes have been explored for CO2 conversion for the production of important industrial chemicals and fuels including C2-C4 lower olefins (e.g. ethylene, propylene), liquid hydrocarbon fuels, methanol as well as aromatics. The key to effective CO2 conversion and utilization is to develop highly selective and active catalysts and catalytic processes for converting CO2 along specific reaction pathways to desired chemicals and fuels. The ultimate goal of our research is to develop a new CO2-based sustainable supply of chemicals, materials and fuels.
