In recent years, there has been a growing call to reduce greenhouse gas emissions, and attention has focused on the development of Carbon Capture and Utilization (CCU) technology, which captures carbon dioxide emitted from power plants and factories and recycles it. Among these, CO2 Capture and Reduction (CCR) —which enables both CO2 capture and conversion into valuable products on a single material—was expected to be a low-cost, energy-efficient process.However, existing materials and methods required heating to temperatures above 350°C to drive the reaction, creating a counterproductive situation where fossil fuels had to be burned to generate that heat.
Our research group has demonstrated that, by using a dual-function catalyst capable of both CO₂adsorptionand conversion, and by applying a small amount of electrical energy, it is possible to repeatedly recover and convert CO₂ under significantly lower-temperature conditions—specifically at 150°C—where unused waste heat can be utilized. This development holds promise for the realization of a highly efficient, energy-saving CCU technology that relies solely on surplus clean electricity and low-temperature waste heat.
