Which way? The decomposition of acetylene on a Rh(100) single crystal is studied using a combination of experimental techniques and a computational approach based on density functional theory (DFT). Acetylene adsorbs irreversibly on the Rh(100) surface and decomposes to atomic carbon and gas-phase hydrogen. The investigation enables the authors to determine the most likely reaction pathway for the decomposition process (see figure).
