SUTD and A*STAR researchers produced a quick and energy-efficient technique to rapidly synthesise 2D mica nanosheets for effective carbon dioxide capture, advancing the research of the power generation sector, environmental and regulatory agencies and scientists in mitigating carbon emissions.

Global warming has been attributed to the sharp increase in heat-trapping greenhouse gas emissions, in particular CO2 emissions. Carbon capture technology, such as using adsorbents to capture and store CO2 from ambient air, is a promising solution to mitigate emissions.
Liquid sorbents are traditionally used for carbon capture, but they suffer from equipment corrosion, high cost and high energy requirements for regeneration. To overcome these limitations, solid porous materials for CO2 adsorption—in which CO2 atoms adhere to the surface of the solid material—are being explored. In his carbon capture research, Associate Professor Wu Ping of the Singapore University of Technology and Design (SUTD) turned to mica, a cheap and abundant clay mineral with diverse applications.
