Chemical reactions occur when elements or compounds combine and create new compounds. Elements are substances that contain only one type of atom and are represented by unique symbols on the periodic ...

Hydrogen is a highly combustible gas that, if produced in an environmentally friendly manner, can help the world meet its clean energy goals. The main impediment to producing hydrogen gas from water ...

Electrical current is applied to water containing Na2SO4 as an electrolyte. The water is converted into gaseous H2 and O2 at the electrodes. Attach one alligator clip from the battery pack to each ...

The electrolytic film produced at Rice and tested at Houston is a three-layer structure of nickel, graphene and a compound of iron, manganese and phosphorus. The foamy nickel gives the film a large ...

A team of researchers has found one of the most effective catalysts ever discovered for splitting oxygen atoms from water molecules -- a key reaction for advanced energy-storage systems, including ...

The global transition toward sustainable energy hinges on efficient electrochemical technologies such as fuel cells, water electrolyzers, and CO₂ electrolysis. These devices rely heavily on catalysts ...

A new solar-electrolysis system uses a copper-doped catalyst to turn farm waste into hydrogen and valuable formate.
