The synthesis of ultrasmall-sized nanoparticles (NPs) has attracted serious attention in the past several years because of the largely increased surface-to-volume ratio of these NPs. Ligands are necessarily used to synthesize these NPs. However, the traditional ligands employed in the colloidal synthesis process would be strongly adsorbed on the surface of the metal NPs, leading to incomplete exposure of catalytically active sites. Here, we develop an efficient solid-state method to synthesize carbon-supported extra-small ligand-free Pt nanoparticles (Pt SNPs/C) or Pd SNPs/C on a large scale (up to gram equivalent). The strong interfacial interaction between the modified carbon support and inorganometallic precursor is believed to successfully prepare this Pt SNPs/C catalyst. In particular, the fabricated Pt SNPs/C catalyst is ligand-free, which is carefully verified by different techniques (thermogravimetric anal., XPS, and “electrochem. surface area (ECSA)” measurement). Because of the higher ECSA, Pt SNPs/C exhibits better catalytic activities toward methanol oxidation and hydrogen evolution than com. Pt/C. By applying the catalyst as both the anode and cathode in a methanol-assisted water splitting system, the cell displays much better efficiency to produce highly valued hydrogen compared to that of com. Pt/C components. This study involved multiple reactions and reactants, such as Sodium tetrachloropalladate(II) (cas: 13820-53-6Safety of Sodium tetrachloropalladate(II)).
Sodium tetrachloropalladate(II) (cas: 13820-53-6) belongs to organic chlorides. Organic chlorides are compounds containing a carbon-chlorine bond, which are widely used in the oil field as a wax dissolver. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.Safety of Sodium tetrachloropalladate(II)
