A new research study has described the connections between small copper clusters that are used as low-cost catalysts for the hydrogen production. This is done by breaking down the water molecules. The copper nanoparticles that are dispersed in water or are in the form of coatings have a wide range of promising applications, such as ink jet printing, lubrication, luminescent probes, exploiting their antifungal and antimicrobial activity and in the fuel cells. In addition to this, another promising application is making use of the copper as a catalyst to split water molecules and form the molecules hydrogen in the form of gas.
According to a recent paper that has been published in the EPJ D., stated that the in the reaction, the copper-water complexes are particularly synthesized in the ultra-cold helium nanodroplets as an important part of the hydrogen production process. Stefan Raggl, the author of the research study from the University of Innsbruck, Austria and colleagues added that the splitting water is considered as a good way for avoiding splitting hairs.
The previous theoretical work have showcased that a monolayer of water, which once adsorbed on the copper particles that spontaneously converts into a half-monolayer of hydroxide along with a half a monolayer of water by releasing the hydrogen gas. Furthermore, in the research study, the researchers have synthesized the neutral copper-water complexes by efficiently doping the helium nano-droplets, which are stored at an ultra-cold temperature of around .37 K in a state, which have been referred as a superfluid, along with the water molecules and copper atoms.
