For platinum catalysts, smaller may be better

When it comes to metal catalysts, the platinum standard is, well, platinum! However, at about $2,000 an ounce, platinum is more expensive than gold. The high cost of the raw material presents major challenges for the future ...

Going platinum: New catalyst could boost cleaner fuel use

(PhysOrg.com) -- Material scientists at Washington University in St. Louis have developed a technique for a bimetallic fuel cell catalyst that is efficient, robust and two to five times more effective than commercial catalysts. ...

Double-layered catalyst generates more hydrogen

Hydrogen-generating catalysts can create synergistic effects when different materials are layered with their unique properties. Recently, a Korean research team has developed a technology to enhance the hydrogen generation ...

Cathodic corrosion—devastating but predictable

An indian stepwell on a nanoscale. That is what postdoc Nakkiran Arulmozhi calls the pattern he saw when he corroded a special kind of platinum crystal. The unique images show the destructiveness of the process, but also ...

New research shows the limitations of coordination in chemistry

A common assumption in chemistry is that the coordination number of a catalyst's surface determines the reactivity of the reaction it catalyzes. Strikingly, chemists from Leiden University have now proven that this is not ...

The roughening of a platinum electrode

Smooth platinum electrodes roughen and wear when subjected to repeated cycles of oxidation and reduction, which causes nanometer scale mounds to grow. Leiden chemists Leon Jacobse and Mark Koper, together with physicist Marcel ...

New catalyst for making fuels from shale gas

Methane in shale gas can be turned into hydrocarbon fuels using an innovative platinum and copper alloy catalyst, according to new research led by UCL (University College London) and Tufts University.

Harnessing light to drive chemical reactions

An exotic interaction between light and metal can be harnessed to make chemical reactions more sustainable, but the physics behind it has been widely debated in the field.
