The key issue for industrial large-scale hydrogen production by water electrolysis is developing environment-friendly electrocatalysts that can work well at large current densities and low overpotentials. Thanks to the superior advantages of 2D graphdiyne (GDY) on chem. structure and the alkyne bond strong reductivity, the highly selective, in situ growth of the single-crystal Pd (111) quantum dots is achieved. The metal dots distribute uniformly and densely on the GDY surface (GDY-Pd1) in a controllable way at low temperatures without adding addnl. reductive agents. Exptl. and theor. results show that the 2D GDY affords an ideal platform to construct highly selective and active electrocatalysts with accurate structures, defined valence states, facilitated charge transfer ability, and enhanced elec. conductivity for hydrogen evolution reaction. Remarkably, the electrocatalyst can reach 500 and 1000 mA cm-2 at small overpotentials of only 201 and 261 mV, with high long-term stability, which are better than most of the reported ones. The results demonstrate that 2D DGY is an excellent support in the controllable synthesis of metal quantum dots with well-defined surface and structure and the potential to achieve large-scale preparation This study takes a critical step toward industrial hydrogen production This study involved multiple reactions and reactants, such as Sodium tetrachloropalladate(II) (cas: 13820-53-6COA of Formula: Cl4Na2Pd).
Sodium tetrachloropalladate(II) (cas: 13820-53-6) belongs to organic chlorides. Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.COA of Formula: Cl4Na2Pd
