Perspectives of use of activated carbon materials modified with transition metal oxides for purification of water from arsenic were considered. Sorption isotherms for two types of hybrid sorbents based on carbon fibers modified with manganese oxide as birnessite as well as on fiber and chitosan-carbon materials on its basic modified with molybdenum determining affinity of the sorbents to arsenate-ions are presented.

Lithium Ion Conductivity

Proton transport in nanochannels under humid conditions is crucial for the application in energy storage and conversion. However, existing materials, including Nafion, suffer from limited conductivity of up to 0.2 siemens per centimeter. We report a class of membranes assembled with two-dimensional transition-metal phosphorus trichalcogenide nanosheets, in which the transition-metal vacancies enable exceptionally high ion conductivity. A Cd0.85PS3Li0.15H0.15 membrane exhibits a proton conduction dominant conductivity of ~0.95 siemens per centimeter at 90° Celsius and 98% relative humidity. This performance mainly originates from the abundant proton donor centers, easy proton desorption, and excellent hydration of the membranes induced by cadmium vacancies. We also observed superhigh lithium ion conductivity in Cd0.85PS3Li0.3 and Mn0.77PS3Li0.46 membranes.
