Direct observation of carbon dioxide adsorption and binding at the air/aqueous interface.

ABSTRACT: Carbon dioxide removal (CDR) involves reducing carbon dioxide (CO₂) concentrations. Developing new technologies and enhancing existing ones for extracting and converting CO₂ are ongoing areas of research. In all these technologies, the movement of CO₂ molecules through an interface is a common process. At liquid surfaces, the nanometer-thick interfacial region is expected to play a fundamental role in enhancing or hindering the process. The interface can have significantly different conditions, such as pH, ion concentration, and ion speciation, compared with the bulk. Despite this, our knowledge of the molecular-scale details of CO₂ capture and conversion at liquid interfaces is limited. Here, we report direct observation of CO₂ surface adsorption and conve
