Thermo-catalytic reduction of CO2 to value-added products on supported Cu nanostructures and bimetallic Cu nanoalloys

Abstract

In the wake of industrialization, humanity has faced the daunting challenge of mitigating the environmental repercussions of harmful pollutant emissions. Among these, the rise in carbon dioxide (CO2) levels is a pivotal concern. The alarming shift in climate patterns brings forth an array of issues. Negative emission technologies like Carbon Capture, Utilization, and Storage (CCUS) are imperative. Our research focuses on the thermocatalytic reduction of CO2 to generate value-added chemicals and/or hydrogen carriers, a fundamental component of artificial CO2 utilization. Through thermo-catalysis, CO2 captured from the air can be converted into valuable compounds, such as organic chemicals, hydrocarbon fuels, and polymers. Among these, methanol production holds promise due to its ease of storage and transport, and its role in synthesizing essential chemicals and fuels. Considering the above aspects, this research aims to develop an advanced heterogeneous catalyst for CO2 hydrogenation to methanol by optimizing catalyst properties, feed gas composition, and use of water as solvent. The present research is poised to significantly contribute to the field of catalysis, steering us closer to a greener and more sustainable future, in alignment with global efforts to combat climate change and reduce our carbon footprint.
