Abstract
Catalyst systems employing inexpensive and readily-available protic co-catalysts to increase a proton reduction rate in a hydrogen evolution reaction (HER) are described herein. The protic co-catalysts function to increase the rate without being consumed in the process of water splitting to hydrogen and oxygen. They may simultaneously serve to stabilize the pH of the water and be the electrolyte to carry the current for the electrolytic splitting of water. The protic co-catalysts also decrease the overpotential energy requirement for the process of water splitting. These protic co-catalysts can be used with both heterogeneous and homogenous catalysts, as well as assist photocatalysis and other processes for the reduction of protons.
