Single Atom Ruthenium‐Doped CoP/CDs Nanosheets via Splicing of Carbon‐Dots for Robust Hydrogen Production

Abstract: Ultrathin two-dimensional catalysts are attracting attention in the field of electrocatalytic hydrogen evolution. This work describe acomposite material design in which CoP nanoparticles doped with Ru single-atom sites supported on carbon dots (CDs) single-layernanosheets formed by splicing CDs (Ru 1 CoP/CDs). Small CD fragments bore abundant functional groups,analogous to pieces of ajigsaw puzzle,and could provideahigh density of binding sites to immobilize Ru 1 CoP.The single-particle-thicknanosheets formed … Show more

“…SACs may be the best solution for Ru-based catalysts because of the maximum utilization of Ru atoms and the exposure of active centers. Presently, Ru SACs with different loadings have been prepared on various carriers, such as phosphors [ 91 , 92 ], MOF [ 93 ], Graphdiyne [ 94 ], MXene [ 95 , 96 ], and nitrogen-doped carbon [ 97 ].…”

“…Various Ru species, such as metal nanoparticles (NPs), alloys, oxides, phosphides, and selenides, have shown excellent HER activity. [19][20][21][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39] Accumulative knowledge indicates that the size and dispersity of the active species have a significant influence on their electrocatalytic performance. [40][41][42][43][44] In particular, ultrasmall sizes (for example, sub-2 nm) and high dispersion are extremely attractive characteristics because they provide unique quantum confinement effects, increased specific surface area, and a high ratio of electrocatalytic active superficial atoms.…”

“…Compared with conventional supported nanocatalysts, SACs have shown distinctive advantages in improving metal utilization efficiency [5] and maximizing the metal‐support interface [6] , thus exhiting superior catalytic performance (activity and/or selectivity). The synthetic methods of SACs have rapidly developed [7,8] , and a variety of materials have been utilized as support, such as carbon materials [9,10] , porous materials (zeolites [11] , Al 2 O 3 [12] metal‐organic frameworks [13] ), two‐dimensional materials, and so on [14] . In particular, oxide supported SACs have been mostly used in industrial‐related thermocatalytic applications for the mechanical and thermal stability of oxides.…”
