Chemical reaction network showing the major CO destruction pathways and important competing reactions. Red arrows show reactions that are mediated directly or indirectly by cosmic-ray photons, yellow arrows show hydrogenation reactions and blue arrows show grain-surface reactions. The initial major carbon carrier (CO) is shown in grey-purple. Stable products of CO processing are denoted with blue boxes. sX denotes that species X is on the grain surface.
