摘      要：CONSPECTUS:Hydrogen evolution by the electrolysis of water is an important energy conversion process,especially for some intermittent energy systems.However,its practical applicability is limited by its low energy-conversion efficiency and the need for expensive electrocatalysts.In response,carbon-based nanocomposites have gained substantial interest as promising alternatives to the currently used precious metal catalysts.Among them,carbon dots(CDs)have exhibited many outstanding features,including flexible composition,high conductivity,good dispersion,and strong metal coordination.The past decade has seen remarkable advances in CD-based electrocatalysts for hydrogen evolution,where CDs and their derived hybrids have shown impressive performance and indispensable prospects for future hydrogen utilization.However,the widespread use of CD-based electrocatalysts still requires the development of high-quality CDs and advanced synthesis strategies.New assessment techniques are also required to elucidate the unique functions of CDs in composition regulation,structure fabrication,surface modification,and host−guest interactions in electrocatalysts and ultimately to establish the relationships among structure,composition,and activity.
