Cheap catalyst coaxes hydrogen from the lawn

Cheap catalyst coaxes hydrogen from the lawn:

Scientists have shown how sunlight and a cheap catalyst can unlock significant amounts of hydrogen from fescue grass.

The method, now demonstrated for the first time, could potentially lead to a sustainable way of producing hydrogen, which has enormous potential in the renewable energy industry due to its high energy content and the fact that it does not release toxic or greenhouse gases when it is burned.

“This really is a green source of energy,” says coauthor Michael Bowker, a professor at the Cardiff Catalysis Institute. “Hydrogen is seen as an important future energy carrier as the world moves from fossil fuels to renewable feedstocks, and our research has shown that even garden grass could be a good way of getting hold of it.”

New model predicts once-mysterious chemical reactions

New model predicts once-mysterious chemical reactions:

A team of researchers from Los Alamos National Laboratory and Curtin University in Australia developed a theoretical model to forecast the fundamental chemical reactions involving molecular hydrogen (H2), which after many decades and attempts by scientists had remained largely unpredicted and unsolved.

“Chemical reactions are the basis of life so predicting what happens during these reactions is of great importance to science and has major implications in innovation, industry and medicine,” said Mark Zammit, a post-doctorate fellow in the Physics and Chemistry of Materials group at Los Alamos National Laboratory. “Our model is the first to very accurately calculate the probability of fundamental electron-molecular hydrogen reactions.”
