Front Cover: Ruthenium Ion‐Complexed Graphitic Carbon Nitride Nanosheets Supported on Reduced Graphene Oxide as High‐Performance Catalysts for Electrochemical Hydrogen Evolution (ChemSusChem 1/2018)

The Front Cover shows the production of hydrogen gas when electrons and protons meet on ruthenium ion‐complexed graphitic carbon nitride nanosheets supported on graphene surface. The image is based on an ancient Chinese legend of Niulang ( ) and Zhinü ( ). Niulang was a human cowherd and Zhinü was a fairy from heaven. They fell in love with each other. Yet their love was banned by the fairy's queen, who forcefully separated them by the Silver River. The lovers were only able to see each other once a year, on the 7th day of the 7th lunar month, with the help of a flock of magpies that formed a bridge.
