Defect-free graphene is impermeable to all atoms1-5 and ions6,7 under ambient conditions. Experiments that can resolve gas flows of a few atoms per hour through micrometre-sized membranes found monocrystalline completely helium, the smallest atom2,5. Such were also shown be ions, including one, lithium6,7. By contrast, was reported highly permeable protons, nuclei hydrogen atoms8,9. There no consensus, however, either on mechanism behind unexpectedly high proton permeability10-14 or even...
The basal plane of graphene can function as a selective barrier that is permeable to protons but impermeable all ions and gases, stimulating its use in applications such membranes, catalysis isotope separation. Protons chemically adsorb on hydrogenate it, inducing conductor-insulator transition has been explored intensively electronic devices. However, both processes face energy barriers various strategies have proposed accelerate proton transport, for example by introducing vacancies,...
The ozone is one of the classical atmospheric pollutants that adversely affect human health and ecological environment. In this paper, carbonaceous catalysts derived from MOFs with different structural topologies...
Abstract Strong electric fields can accelerate molecular dissociation reactions. The phenomenon known as the Wien effect was previously observed using high-voltage electrolysis cells that produced of about 10 7 V m −1 , sufficient to weakly bound molecules (e.g., organics and weak electrolytes). observation for common case water (H 2 O $$\leftrightarrows$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mo>⇆</mml:mo> </mml:math> H + OH − ) has remained elusive. Here we study...

Abstract Recent experiments demonstrated that proton transport through graphene electrodes can be accelerated by over an order of magnitude with low intensity illumination. Here we show this photo-effect suppressed for a tuneable fraction the infra-red spectrum applying voltage bias. Using photocurrent measurements and Raman spectroscopy, such selected tuning Fermi energy electrons in bias, phenomenon controlled Pauli blocking photo-excited electrons. These findings demonstrate dependence...
Recent experiments demonstrated that interfacial water dissociation (H2O ⇆ H+ + OH-) could be accelerated exponentially by an electric field applied to graphene electrodes, a phenomenon related the Wien effect. Here we report order-of-magnitude acceleration of reaction under visible-light illumination. This process is accompanied spatial separation protons and hydroxide ions across one-atom-thick enhanced strong fields. The found photoeffect attributed combination graphene's perfect...
