Defects and jagged surfaces at the edges of nanosized platinum and gold particles are key hot spots for chemical reactivity, researchers confirmed using a unique infrared probe.
Berkeley Lab scientists have found a way to engineer the atomic-scale chemical properties of a water-splitting catalyst for integration with a solar cell, and the result is a big boost to the stability and efficiency of artificial photosynthesis. The research comes out of the Joint Center for Artificial Photosynthesis (JCAP), established to develop a cost-effective method of turning sunlight, water, and carbon dioxide into fuel.
Five researchers at Berkeley Lab were named today as recipients of the Early Career Research Program managed by the U.S. Department of Energy’s Office of Science. The program is designed to bolster the nation’s scientific workforce by providing support to exceptional researchers during the crucial early career years, when many scientists do their most formative work.
Berkeley Lab researchers have incorporated molecules of porphyrin CO2 catalysts into the sponge-like crystals of covalent organic frameworks (COFs) to create a molecular system that not only absorbs CO2, but also selectively reduces it to CO, a primary building block for a wide range of chemical products.
Berkeley Lab researchers using a bioinorganic hybrid approach to artificial photosynthesis have combined semiconducting nanowires with select microbes to create a system that produces renewable molecular hydrogen and uses it to synthesize carbon dioxide into methane, the primary constituent of natural gas.
Earlier this year, Berkeley Lab’s Molecular Foundry got a new suite of robotic synthesis tools called the Overture and the Symphony X (pictured above), automated chemical synthesizers that assemble custom molecular structures called peptoids. Peptoid nanostructures, pioneered at Berkeley Lab, have molecular shapes similar to biological molecules like proteins, but are made with synthetic building
