New paper exploring carbon capture

Professor Meihong Wang has a new paper published in Energy & Environmental Science Heterojunction-redox catalysts of Fe_xCo_yMg₁₀CaO for high-temperature CO₂ capture and in situ conversion in the context of green manufacturing

Reduction of CO₂ emissions from major sources such as power plants and industrial processes is critical to achieving the COP21 target of limiting the average global temperature increase to well below 2 °C above the pre-industrial level. Carbon capture and storage will play a vital role in delivering 19% of the cumulative CO₂ emission reductions between 2015 and 2050 worldwide. 

With the increasing crisis of global warming, carbon capture, utilization and storage (CCUS) technology has been demonstrated to be an effective solution to address global climate change. Currently, most CCUS studies focus on the power generation sector and explore carbon capture, utilization and storage separately. Accordingly, after carbon capture, CO₂ purification, compression and transportation are necessary for further sequestration, which consume a huge amount of energy. Moreover, the CO₂ emission from industry accounting for about 25% of the total global CO₂ emission has not been systematically explored. 

The paper explores the heterojunction-redox strategy which provides a unique way to design bifunctional adsorbent/catalyst materials. The integrated CaL/RWGS process could be a promising technology for CO₂ capture and utilization.
