Improving Magnesium Borohydride For Solid-state Hydrogen Storage

The key mechanism by which magnesium diboride (MgB2) absorbs hydrogen has been discovered by scientists at Lawrence Livermore National Laboratory (LLNL). The work, through theory and experimentation, also provides important insights into the reaction pathway that converts MgB2 to its highest hydrogen capacity form, magnesium borohydride (Mg(BH4)2). Mg(BH4)2 is a particularly promising hydrogen storage material because of its high hydrogen content and attractive thermodynamics. said Keith Ray, LLNL physicist and the paper’s lead author.

Carbon Dioxide Converted Into Fuel With Ultraviolet Light Catalysis

Nanoparticles that help convert carbon dioxide into methane using only ultraviolet light as an energy source have been developed by researchers at Duke University. The team now hopes to develop a version that would run on natural sunlight, a potential treasure for alternative energy. Chemists have long sought an efficient, light-driven catalyst to power this reaction, which could help reduce the growing levels of carbon dioxide in our atmosphere by converting it into methane, a key building block for many types of fuels.
