Descrizione generale

Platinum (IV)chloride is a weak Lewis acid used in surface modification, nanomaterialsynthesis, and catalysis.

Applicazioni

Platinum (IV) chloride can be used for the surfacemodification of crystalline and amorphous titania powders, to enhance theirphotocatalytic efficiency. Electronsinjected into the conduction band of titania due to visible light excitation ofplatinum (IV)chloride surface complex reduces oxygen to superoxide. The superoxide thusformed is responsible for the photodegradation reaction.

Platinumnanoparticles can be synthesized by reacting platinum (IV) chloride with Cyanobacteriumin an environmentally friendly method.

It can also be used as a dual catalyst forstereo- and regioselective glycosidations. Due to its ligand-bindingcapacity, platinum (IV) chloridehas an affinity for the glycosyl acceptor hydroxy group and forms the glycosidationproduct in β-configuration. It also enhances nucleophilicity differencesbetween hydroxy groups allowing regioselective glycosidation.

Anatase, rutile, and amorphous titania powders were surface-modified by grinding with PtCl4 and H2[PtCl6]. Only the anatase modification afforded hybrid photocatalysts capable of degradation of 4-chlorophenol (4-CP) with visible light, with sufficient stability towards decomplexation. Grinding with K2[PtCl4] produced materials

Pt chemical shifts were calculated from two-component relativistic density functional theory (DFT). The shielding tensors were analyzed by using a recently developed method to decompose the spin-orbit DFT results into contributions from spin-free localized orbitals (here: natural localized molecular orbitals
