Progress For a Efficient Biofuel Cell

November 29, 2018 | 1 Comment

Ruhr-University Bochum researchers have combined two concepts that make a biofuel cell as efficient as precious metal catalysts. Fuel cells that work with the enzyme hydrogenase are, in principle, just as efficient as those that contain the expensive precious metal platinum as a catalyst. However, the enzymes need an aqueous environment, which makes it difficult […]

Enzymes Get A Protective Shield

September 19, 2018 | Leave a Comment

Open Image…Save ImageOpen Image (using #TmpD/ia)… Ruhr-University Bochum researchers have developed a new mechanism to protect enzymes from oxygen as biocatalysts in fuel cells. These enzymes, known as hydrogenases, are just as efficient as precious metal catalysts, but unstable when they come into contact with oxygen. They are therefore not yet suitable for technological applications. The new protective mechanism is […]

A New Way For Light to Drive Water Splitting

September 11, 2018 | Leave a Comment

Open Image…Save ImageOpen Image (using #TmpD/ia)… Researchers at St John’s College, University of Cambridge have used semi-artificial photosynthesis to explore new ways to produce and store solar energy. They used natural sunlight to convert water into hydrogen and oxygen using a mixture of biological components and human-made technologies. The researchers have successfully split water into hydrogen and oxygen by altering […]

An Important Hydrogen Producing Enzyme Analyzed

April 4, 2017 | Leave a Comment

Ruhr-University Bochum researchers have analyzed how green algae manufacture complex components of a hydrogen-producing enzyme. The enzyme, known as the hydrogenase, may become relevant for the biotechnological commercial production of hydrogen. So far, little is known about the way organisms form this type of hydrogenases under natural conditions. Using novel synthetic biology methods, the team […]

Breakthrough Bio Catalyst For The Hydrogen Economy

January 7, 2016 | 2 Comments

Indiana University (IU) researchers have reported a highly efficient biomaterial has been created that catalyzes the formation of hydrogen. The novel catalyst also works in reverse to recombine hydrogen and oxygen to generate power. The catalyst makes up one half of the “holy grail” of splitting H2O to make hydrogen and oxygen for fueling cheap […]
