Hydrogen spillover assisted by oxygenate molecules over nonreducible oxides

Nature Communications, 2022
Spontaneous migration of H-atoms from metal particles to a nonreducible oxide support is generally limited by thermodynamics. Here, small oxygenate molecules are found to act as effective H-carriers to promote this process and lead to much improved ...
