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.
Claims18
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 cycloalkanol 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.
