Overview
Researchers have developed a catalytic method for the one-step conversion of carbon dioxide (CO₂) into methane (CH₄). This process utilizes copper phthalocyanine, an accessible and cost-effective blue pigment, as the primary catalytic material. The development was a collaborative effort involving a joint research team led by Tohoku University's Advanced Institute for Materials Research (WPI-AIMR), alongside Hokkaido University and the startup AZUL Energy. The reported catalyst facilitates the direct and efficient transformation of CO₂ to CH₄.
Research Context
The research addresses the conversion of carbon dioxide, which is identified as an industrial waste product. The objective was to convert this CO₂ into a useful fuel, specifically methane. The selection of catalyst material focused on its potential to achieve high efficiency in this transformation while also being inexpensive and readily available.
