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 ...

On paper, the workings of a hydrogen fuel cell sound straightforward enough: An electrochemical reaction occurs between hydrogen and oxygen that converts chemical energy into electrical energy. In ...

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 ...

Potassium- and calcium-modified ilmenite oxygen carriers, developed by the Institute of Science Tokyo, significantly improve hydrogen yields and redox reaction efficiency in chemical looping systems.

Electrochemical catalysts used in water splitting often show poor performance due to low electrical conductance of (oxy)hydroxide species produced in situ. To overcome this challenge, researchers have ...

Natural clay magadiite containing silicon (Si) was heated in a sealed vessel in a water-based solution containing iron chloride (FeCl 3) and nickel chloride (NiCl 2) to create a metallic silicate made ...

Nuclear waste and a hydrogen economy may seem poles apart, but a new study by the University of Sharjah claims that spent ...

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.
