一般描述

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.

应用

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.

特点和优势

与双（二硫醇盐）反应形成金属-双（二硫醇盐），可应用于激光Q开关材料、液晶、光学CD刻录介质、条形码材料和超导体。 与封端聚合物反应形成用于催化和光催化剂的形状控制胶体铂纳米颗粒。
