Experiments by researchers at the University of Manchester have found that the atom is a type of common mineral found in each form of thin mic - soil, and is an excellent proton conductor, and this amazing result results in fuel cells and other hydrogen-related technologies, As such, it is important to use 2-D materials in applications.
Researchers have conducted many experiments before, with Manchester researchers led by Professor Andre Geim and Dr. Marcelo Lozada-Hidalgo finding that, like graphene, a one-atom thick material is highly permeable to the nuclei of protons, hydrogen atoms. However, researchers also found that there are many other 2-D substances, like molybdenum sulfide (MoS2), which had only three atoms thick, and are completely impermeable to protons.The results of the experiment by the same researchers suggested that any one-atom thick crystal can be permeable to protons.
Researchers, writing in Nature Nanotechnology, have shown that protons can allow very easily, through multiple layered micas, and are about 10 times thicker than graphene, because micas and graphite Like, crystal layers stacked on top of each other, and can be moved down to one layer, the team of researchers separated one of these layers, and this Or, that was 100 times more permeable to protons than Graphene proton.
The team of researchers said that at first, this result seemed impossible to come up with, because micas are too thick for protons, and this monolayers are much thicker than MoS2, and would be completely impermeable to protons. However, the researchers pierced the tubular channels in their experiment, and it was found that the mic can be thought of as a crystal slab, because the channels are not empty, but are filled with hydroxyl groups, because it In water the protons of a one-dimensional chain operate, and these protons jump along these chains, and this makes the material an excellent proton conductor Switch to change.
During the project, Lucas Mogg and a Ph.D. he said.We have found that the proton conductivity in the atom-thin mic is 10 to 100 times greater than that of graphene, and this is encouraging, as it was previously considered graphene to be a promising protecting material.Researchers' results show that mikes can be more promising because they are the least abundant and inexpensive.
Professor Andre Geim believes that this can also result in many other 2-D materials being turned into proton conductors. Professor Andre Geim states that our strategy is not limited to protons or micas only.And it is similar to mic with many 2-D crystal atomic-scale channels.Professor Andre Geim says that we can, that will bring many unexpected events, and fresh new applications in the field of protons and ionic conductors.
Researchers have also found in their experiment, mikes are highly conductive in temperature range, and are notorious for related technologies.Dr,Marcello Lozada-Hidalgo states that there is a shortage of proton-carrying materials, and that they can work reliably between 100 ° C and 500 ° C. However, it is the sweet spot temperature range for optimal operation of many fuel cells and for, and each of the hydrogen technologies, and atmoli-thick mikes in this temperature range work correctly, and they draw attention from this point of view.
And in addition to all this, the researchers believe that they are now working on making a mica prototype membrane, and this is a large enough test for industrial conditions, the area of two-dimensional ionic conductors, and the properties of each crystal Promises more, and can be converted into other ionic and proton conductors.
