Abstract

During our studies on surface engineering, we photopolymerize syngas onto silicon surfaces. XPS and TOF-SIMS analyses show that the syngas-derived oligomer covalently bonds to free silanol sites. Iron atoms appear in the coating, despite the fact that no iron was (intentionally) added to the system. GC–MS analysis reveals low concentrations of iron pentacarbonyl (IPC) are generated within the carbon monoxide cylinder. Its presence plays a determinant photocatalytic role in the reaction.
