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 ...

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 ...

Chemists Joel Rosenthal and Daniel G. Nocera of the Massachusetts Institute of Technology provide this answer. When molecular hydrogen (H 2) and oxygen (O 2) are combined and allowed to react together ...

A single, robust catalyst that splits water into hydrogen and oxygen has been developed with Earth-abundant materials that approach the efficiency of more expensive platinum, according to scientists.
