Bleach in gold
Perfumed, utilized as a disinfectant and cleaning agent for surfaces, or as a whitener for laundry, bleach is certainly among the most versatile products utilized in our homes.
This substance is traditionally produced using an energy-intensive process.
The economics of the current production method requires H2O2 to be produced in large quantities and in solutions with concentrations much higher, and less stable, than those used in most practical applications.
Now, a group of chemists and materials scientists from the UK and the US – in an article published on February 20th on “Science” magazine (www.sciencemag.org) – maintain that a carefully tailored alloy of palladium and gold nanoparticles catalyzes the direct production of H2O2 while “switching off” the decomposition of the compound. The breakthrough, which culminates more than five years of research on the topic, promises to enable the on-site production of H2O2 in smaller quantities and more desirable concentrations.
Filling process for such products like bleach has already been argued on a previous post: EXACTA/RC 28/8/8, the new generation filler
