JCAP

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.

A High Throughput Bubble Screening Method for Combinatorial Discovery of Electrocatalysts for Water Splitting

Widespread deployment of many renewable energy technologies hinges upon the discovery of highly active Earth-abundant catalysts. These superior catalysts can be discovered by synthesizing new materials combining 3, 4 or more elements. Due to the vast number of possible combinations of Earth-abundant elements, high throughput screening of these catalysts is required, prompting the development of new experimental techniques. The Joint Center for Artificial Photosynthesis (JCAP) has developed a bubble screening method that in one minute can identify the most active electrocatalysts out of an array of hundreds to thousands of materials.
