Abstract

Photocatalytic materials are drawing significant attention because of their potential for solving environmental and energy problems. Among these problems are finding ways to address the contributions of carbon dioxide (CO2) to global warming while still meeting energy needs. One potential avenue for reduction of greenhouse gases, such as CO2, has been CO2 photoreduction. During this process, CO2 is reduced to less harmful and more useful products, such as methane, using a photocatalyst that is activated by ultra-violet (UV) radiation. However, several challenges still exist related to photocatalyst selection and reactor design. Therefore, there is a need for effective, reliable and cost-effective systems and methods for the photocatalytic conversion of CO2 to reduced products. Researchers at Arizona State University have developed a system and method for the photocatalytic reduction of CO2 in a fluidized bed reactor. The invention uses a microjet-assisted fluidized bed arrangement that is modified so as to allow photocatalytic operation. This solves the issues of other techniques by allowing contact between the reactants and the source of UV radiation. Additionally, the system is scalable to commercial applications. Potential Applications ?Converting CO2 emissions into useful products ?Recycling CO2 emissions from power plants ?Recycling CO2 emissions from automobile exhaust Benefits and Advantages ?Improved efficiency Optimizes photoreduction by using a microjet-assisted fluidized bed. ?Scalable System can be scaled-up for commercial applications. ?Improvement on existing technology - Addresses need for higher volume and flow rate. ?Environmentally-friendly Converts a harmful greenhouse gas into useful products.
