Due to the importance of oscillation amplitude endpoints in low gamma γ B-A catalytic systems, the efficiency of low gamma systems was evaluated in Figure as a function of both oscillation amplitude and oscillation amplitude endpoint in a flow reactor. As observed in the low gamma batch reactor results in Figure -13C, the forward A → B reaction (yellow-to-red) was only enhanced at oscillation endpoints up to the delta point. Once stronger binding energies were imposed on the system, the B → A reaction (blue) was highly favorable due to the dominant surface coverage of A*. The highest observed efficiency here was ~16 %, specifically for the B → A reaction.
