Dethroning Electrocatalysts for Hydrogen Production with Inexpensive Alternative Material

Dethroning Electrocatalysts for Hydrogen Production with Inexpensive Alternative Material

Today, we can say without a shadow of doubt that an alternative to fossil fuels is needed. Fossil fuels are not only non-renewable sources of energy but also among the leading causes of global warming and air pollution. Thus, many scientists worldwide have their hopes placed on what they regard as the fuel of tomorrow: hydrogen (H2). Although H2 is a clean fuel with incredibly high energy density, efficiently generating large amounts of it remains a difficult technical challenge.

Water splitting — the breaking of water molecules — is among the most explored methods to produce H2. While there are many ways to go about it, the best-performing water splitting techniques involve electrocatalysts made from expensive metals, such as platinum, ruthenium, and iridium...

Courtesy of NASA/JPL-Caltech Using new geochemical models, SwRI scientists found that CO2 in Enceladus’ ocean may be controlled by chemical reactions at the seafloor. Integrating this finding with previous discoveries of H2 and silica suggests geochemically diverse environments in the rocky core. This diversity has the potential to create energy sources that could support life.

Enceladus’ subsurface ocean composition hints at habitable conditions. A Southwest Research Institute team developed a new geochemical model that reveals that carbon dioxide (CO2) from within Enceladus, an ocean-harboring moon of Saturn, may be controlled by chemical reactions at its seafloor...

Trihydrogen, H3+, is called the molecule that made the universe, where it plays a greater role in astrochemistry than any other molecule. While H3+ is astronomically abundant, no scientist understood the mechanisms that form it from organic molecules. Until now. Using lasers, Michigan State University scientists have unlocked the secret and published their results in the current issue of Scientific Reports...
