A catalyst for the electrolysis of water molecules and hydrocarbons, said catalyst comprising A 1- x B 2 - y B ' y O 4 spinel with a cubic M 4 O 4 core, wherein A is Li or Na and B and B 'is independently a transition metal or a main group metal, M is B, B', or both B and B ', x is 0 to 1, and y is 0 to 2 do. In photo-electrolytic applications, a plurality of catalytic groups are supported on a conductive support substrate capable of containing water molecules. At least some of the catalytic functional groups supported by the support substrate may catalytically interact with water molecules contained in the support substrate. The catalyst may also be used as part of a photo-electrochemical cell for electrical energy recovery. |
