Researchers at the University of Zurich have been adding zinc sulfide to the appearance of indium-based quantum faces, opening up no nanoparticles. Those quantum faces are bred from the fire and the sun produces a clean hydrogen fuel - a non-continuous energy source. They introduced new environmentally friendly and weak materials for solar photocatalysis.

The quantum face is a true homogeneous person. Those textures of only a few nanometers represent actions that do not take about atomic similarities, and do not systematically modulate their patterns, size and number of electrons. That means that their electrical warfare optical features are tailored to many indicator areas, such as new performance skills, biomedical applications, and photovoltaic warfare.

Using the sun to fight for fuel

Another research that is being used in the face is indirectly producing hydrogen from the sun . Hydrogen is a clean and efficient energy source, whether it is converted into a fuel model that is used throughout, including methanol and gasoline. The most promising example of quantum surfaces used in energy research has been cadmium, which is not banned by many products because of its toxicity. The team of scientists from the University of Zurich, Greta Patzke, who teaches the Southwestern Petroleum University of Chengdu and the Foreign Academy of Sciences, has not yet developed a new type of nanomaterial for photocatalytic non-toxic ingredients.

The three nanoparticles consist of an indium phosphide core warfare, especially a very thick zinc sulfide warp sulfide ligand layer . “Compared with the quantum surface containing cadmium, the new composite material is not only environmentally friendly, but also very efficient when it is producing hydrogen from the light war,” Greta Patzke explained. The discovery of sulfide ligands on the appearance of quantum faces contributes to a critical step in the external touch of light-driven chemical reactions, namely the useful dispersion of charge carriers and the rapid transfer of the appearance of the back nanoparticles.

Great potential for environmental protection

Whether the newly developed cadmium-free nanomaterials can become a more environmentally friendly alternative to various trades. "The fire-soluble biocompatible indium-based quantum face is being tested in the future by conversion of biomass to hydrogen. Probably whether they progress to low-toxic biosensors, probably nonlinear optical materials, for example," Greta Da Patzke.

Further demand: lighter for hydrogen production, less toxic, no recycling light absorber
