The Joint Center for Artificial Photosynthesis (JCAP) is the nation’s largest research program dedicated to the development of an artificial solar-fuel generation technology. Established in 2010 as a U.S. Department of Energy (DOE) Energy Innovation Hub, JCAP aims to find a cost-effective method to produce fuels using only sunlight, water, and carbon dioxide as inputs.

Research Highlights


Heterogeneous Catalysis and Surface Science research in JCAP focuses on the basic understanding of the relationships among the structure, composition, and reactivity of electrocatalysts.  Knowledge gained from surface science experimentation can be implemented toward the discovery of better heterogeneous catalysts for solar-fuel production from carbon dioxide and water.

This video presentation is the first in a series about Heterogeneous Catalysis and Surface Science research in JCAP.
