Graphene Surprise Could Help Generate Hydrogen Cheaply and Sustainably

echo123 shares a report from SciTechDaily: Researchers have discovered that graphene naturally allows proton transport, especially around its nanoscale wrinkles. This finding could revolutionize the hydrogen economy by offering sustainable alternatives to existing catalysts and membranes. [...] In a recent publication in the journal Nature, a joint effort between the University of Warwick, spearheaded by Prof. Patrick Unwin, and The University of Manchester, led by Dr. Marcelo Lozada-Hidalgo and Prof. Andre Geim, presented their findings on this matter. Using ultra-high spatial resolution measurements, they conclusively demonstrated that perfect graphene crystals indeed allow proton transport. In a surprising twist, they also found that protons are strongly accelerated around nanoscale wrinkles and ripples present in the graphene crystal. This groundbreaking revelation carries immense significance for the hydrogen economy. The current mechanisms for generating and using hydrogen often rely on costly catalysts and membranes, some of which have notable environmental impacts. Replacing these with sustainable 2D crystals like graphene could play a pivotal role in advancing green hydrogen production, subsequently reducing carbon emissions and aiding the shift towards a Net Zero carbon environment. [...] The team is optimistic about how this discovery can pave the way for novel hydrogen technologies. Dr. Lozada-Hidalgo said, "Exploiting the catalytic activity of ripples and wrinkles in 2D crystals is a fundamentally new way to accelerate ion transport and chemical reactions. This could lead to the development of low-cost catalysts for hydrogen-related technologies."
