University researchers from two continents have engineered an efficient and environmentally friendly catalyst for the production of molecular hydrogen (H2), a compound used extensively in modern industry to manufacture fertilizer and refine crude oil into gasoline.

But the cost of producing it by using electricity to split water is high, because the most efficient catalysts developed so far are often made with precious metals, like platinum, ruthenium and iridium.

The researchers discovered that these catalysts — copper in the form of a white salt and the ligand as an oil — can oxidize C - H bonds in a very efficient way in combination with hydrogen peroxide, a reduced form of oxygen that nature uses.

Australian scientists have paved the way for carbon neutral fuel with the development of a new efficient catalyst that converts carbon dioxide (CO2) from the air into synthetic natural gas in a «clean» process using solar energy.

Copper is a catalyst — a material used to activate and speed up chemical reactions — and, while it aids in the production of ethanol when exposed to CO2 and water, it is not efficient enough to make large quantities of ethanol.

They also discovered just how their catalyst works, knowledge that could be used to design more efficient catalysts for a wide range of applications.

Chu and colleagues including physicists Zhifeng Ren and Shuo Chen, both of whom also are principal investigators with the Texas Center for Superconductivity at UH, report their discovery — an efficient catalyst produced without the expensive precious metals most commonly used — this week in the Proceedings of the Natural Academy of Sciences.

Scientists from Forschungszentrum Jülich and Technische Universität Berlin have succeeded in developing efficient metallic catalyst particles for converting hydrogen and oxygen to water using only a tenth of the typical amount of platinum that was previously required.

The resulting device marks the most efficient example of a solar - derived carbon dioxide splitter using a low - cost catalyst.

Methods: The team is developing alternative, atom - efficient catalysts that have the potential significantly improve tar reforming performance over the traditionally used nickel - based hydrocarbon - reforming catalysts.

This requires a catalyst that is both efficient in its use of solar photons and fast enough to keep up with solar flux in order to avoid wasting those photons.

Rice University has some neat catalysts that do not use rare earths and are pretty efficient.

Because the technology has already been around for a few years, the main challenge for the students was to develop a cheap, yet efficient, device - one they tackled in part by making use of a non-platinum catalyst, which allowed them to keep manufacturing costs to a minimum.

Using iridium catalyst for artificial photosynthesis could pave way for more efficient means of harvesting and storing solar energy.
