In one aspect, the disclosure relates to a method for oxidizing alkanes to produce industrially useful solvents and other compounds. In a further aspect, the method includes the steps of contacting an alkane or mixture of alkanes with a core-shell nanoparticle and an oxidant to produce a mixture and then irradiating the mixture with UV and/or visible light. The methods are selective for desired products and do not produce overoxidized species such as, for example, carbon dioxide. In a still further aspect, the methods are scalable and can be conducted for a short time under relatively mild conditions. In an aspect, the core-shell nanoparticle includes a metal-oxide containing semiconductor core, an amorphous, radiation transparent shell, and optional metal nanoparticle dopants in the shell. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.
