Because of its toxicity and the dangers involved in handling it, tetrachloromethane (carbon tetrachloride, CCl4) can no longer be used or produced in many countries. However, the processes used in the ...

To reduce the energy requirements of the Haber-Bosch process, which converts nitrogen and hydrogen to ammonia, researchers have developed a metal nitride catalyst containing an active metal (Ni) on a ...

Tsinghua University researchers have developed a way to combine high-cost platinum and a rare earth element, lanthanum, to serve as a catalyst in fuel cells. Meanwhile, SSAB, LKAB, and Vattenfall have ...

Researchers at Tsinghua University have devised a method for combining platinum and lanthanum as an alloy to serve as a catalyst in the next generation of fuel cells which will improve their ...

Researchers have devised a method for combining high-cost platinum and a low-cost rare earth element, lanthanum, as an alloy to serve as a catalyst in the next generation of fuel cells that will ...

Scientists crafting a nickel-based catalyst used in making hydrogen fuel built it one atomic layer at a time to gain full control over its chemical properties. But the finished material didn't behave ...

Lanthanum can operate as a catalyst promoter when rhodium is utilized as a catalyst. Individual lanthanum atoms were inserted on a rhodium nanoparticle’s small surface. The same particle was studied ...

Biodiesel may be a green fuel, but its production has a waste problem. Every year, producers of the alternative fuel create over a million tons of glycerol worldwide, much of which goes to waste.

The Haber-Bosch process, which is commonly used to synthesize ammonia (NH 3)–the foundation for synthetic nitrogen fertilizers–by combining hydrogen (H 2) and nitrogen (N 2) over catalysts at high ...
