Electrocatalysis of Hydrogen Evolution Reaction with metal oxides

I'm new to the topic of electrocatalysis so I have a few questions. Also, I don't have much knowledge about thermodynamics, but I will try to ask anyway.

I'm looking for a material to catalyze the Hydrogen Evolution Reaction for $\ce{H2}$ production. So, for pure metals we have the Volcano curve:

Then, with this curve, I found in literature that we can mix metals from the different branches (positive and negative slopes) and get a new alloy with an intermediate M-H energy strength (which is desirable to improve the catalyst activity.)

But, I want to know if there exists the same curve (and the same logic) for metal oxides, because I need to predict if an alloy of rhenium oxides with copper oxides are going to be a better catalyst than only rhenium oxides.

Is there some method of theory to predict this before going to the lab and doing some experiments?

• Presence of Titanium on this diagram is hilarious. It's good there is no aluminium here, or I'd laughed my ass off. – permeakra Apr 20 '16 at 7:09
