AbstractContinuous and effective hydrogen evolution under high current densities remains a challenge for water electrolysis owing to the rapid performance degradation under continuous large-current operation. In this study, theoretical calculations, operando Raman spectroscopy, and CO stripping experiments confirm that Ru nanocrystals have a high resistance against deactivation because of the synergistic adsorption of OH intermediates (OHad) on the Ru and single atoms.

AbstractMembrane desalination is an emerging technology that shows promise for producing freshwater from saline waters. However, most membranes are challenged by low freshwater flux, impacting the water productivity, energy efficiency and membrane usage. Here we present the submicrometre-thick and nanopore-structured graphdiyne membranes on porous Cu hollow fibres.
