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 ...

Discovery of an efficient artificial catalyst for the sunlight-driven splitting of water into oxygen and hydrogen is a major goal of renewable clean energy research. Scientists have devised a unique ...

WE have made a preliminary survey of the principal respects in which the reaction of deuterium with oxygen differs from that of ordinary hydrogen. The deuterium was prepared by the nearly quantitative ...

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.

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 ...
