Descripción

Descripción general

Potassium tetrachloroplatinate(II) is a crystalline solid that is insoluble in water and soluble in organic solvents. It is widely used in the field of nanomaterial synthesis, catalysis, and energy storage.

Aplicación

Potassium tetrachloroplatinate(II) can be used:

• As a precursor to prepare platinum nanoparticles and mesoporous platinum nanospheres with tunable pore sizes.
• As a catalyst for selective methane oxidation through C-H activation. In addition, to synthesize octahedral Pd@Pt1.8Ni nanocrystals with an ultrathin PtNi alloy shell. The nanocrystals exhibited better ORR activity and durability than the commercial Pt/C for fuel cells.
• To prepare Pt atomic clusters were synthesized using a one-step carbon-defect-driven electroless deposition method. These catalysts demonstrated low overpotential, high activity for the hydrogen evolution reaction, exceptional stability, and improved utilization efficiency of Pt. The Pt-AC/DG (Atomic Clusters/Defective Graphene) cathode showed excellent hydrogen production activity, remarkable stability, and significantly reduced Pt usage compared to the Pt/C catalyst.
• As a starting material to synthesize cyclometalated platinum(II) complexes with long-lived luminescence in solution.

Características y beneficios

Reacts with bis(dithiolates) to form metal-bis(dithiolates) with applications in laser Q-switch materials, liquid crystals, optical CD recording media, bar code materials and superconductivity. Reacts with capping polymers to form shape-control colloidal platinum nanoparticles for catalysis and photocatalysts.
