📄 Abstract（原文）
Integrating carbon capture with direct electrochemical conversion has been suggested as an opportunity to decrease energy and operational costs by utilizing CO2 from dilute sources. The use of amine-based sorbents for CO2 capture has been extensively studied and are commercially available as model liquid sorbents. However, employing amine-based sorbents for direct electrochemical conversion poses challenges such as enhanced competitive hydrogen evolution reactions caused by protonated amines, along with material degradation and corrosion. These issues can influence product selectivity and reactivity compared to systems using pure CO2 as feedstock. While previous work in the field has focused on tailoring catalyst microenvironment to suppress hydrogen evolution reaction, there is limited understanding on how catalyst surface governs reactivity. Here, our goal is to understand the structure and activity relationship between monometallic indium and indium clusters. The purpose is to advance catalyst design by extracting applicable insights from our understanding of direct CO2 reduction and identify key catalyst considerations for utilizing captured CO2 as a feedstock. Catalyst activity is understood from electroanalytical experiments where products are detected by gas chromatography and nuclear magnetic resonance. Material characterization techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM), and X-ray photoelectron spectroscopy (XPS), and scanning transmission electron microscopy (STEM) are used to understand structure.
