Catalysts for selective production of hydrogen peroxide and methods of making and using thereof have been developed. The catalysts include an alloyed or doped metal oxide which permits tuning of the catalytic properties of the catalysts for selection of a desired pathway to a product, such as hydrogen peroxide. The catalysts may be incorporated into electrochemical or photochemical devices.

Composites of silicon and various porous scaffold materials, such as carbon material comprising micro-, meso- and/or macropores, and methods for manufacturing the same are provided. The compositions find utility in various applications, including electrical energy storage electrodes and devices comprising the same.
