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 ...

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.

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 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 ...
