Abstract
Methods of preparing Pt/SrTiO3 photocatalysts comprising strontium titanate nanoparticles and platinum doped on a surface of the strontium titanate nanoparticles are described. Processes of oxidizing cycloalkanes to cycloalkanols and/or cycloalkanones by employing the Pt/SrTiO3 photocatalysts are specified. A method for recycling the photocatalyst is also provided.
Claims20
A process of oxidizing a cycloalkane to a cycloalkanol and/or a cycloalkanone, the process comprising:
- contacting a feed mixture comprising the cycloalkane and an oxidant with a Pt/SrTiO3 photocatalyst thereby forming a reaction mixture;
- and
- concurrently irradiating the reaction mixture with light thereby forming the cycloakanol and/or the cycloalkanone;
- wherein the Pt/SrTiO3 photocatalyst comprises:
- strontium titanate nanoparticles;
- and
- platinum doped on a surface of the strontium inmate nanoparticles;
- wherein the platinum is present in an amount of 0.1-5.0 wt % relative to a total weight of the Pt/SrTiO3 photocatalyst.
A method of producing a Pt/SrTiO3 photocatalyst comprising strontium titanate nanoparticles and platinum doped on a surface of the strontium titanate nanoparticles, the method comprising:
- mixing a strontium(II) salt with an acid to form a first mixture;
- adding a titanium(IV) alkoxide to the first mixture to form a second mixture;
- sonicating, drying and calcining the second mixture to form strontium titanate nanoparticles;
- mixing a platinum(II) compound with the strontium titanate nanoparticles to form a third mixture;
- and
- reducing the third mixture with a reductant to form the Pt/SrTiO3 photocatalyst.
