Adsorption and decomposition mechanism of formic acid on the Ga2O3 surface by first principle studies

First principle calculations on the decomposition mechanism of formic acid on the Ga2O3(100) surface indicate that the mechanism strongly depends on experimental conditions. At low temperature the decomposition would form CO2 and surface hydroxyl groups while at high temperature the catalytic decomposition is through dehydration pathway to CO + H2O with surface oxygen defects as activation center.154
