Abstract Ethanol to butanol (ETB) process is an attractive route to upgrade abundant substrate into a product with superior properties in energy industry. For the mechanism research, the detection of intermediates is vital. In this paper, intermediates in ETB reaction catalyzed by monoxide ions [ZrO]+/[CeO]+/[TiO]+ were investigated by inductively coupled plasma tandem mass spectrometry (ICP-MS/MS). Some important organic small molecule intermediates, metal-adduct intermediates and their formation pathways were discussed to reveal the reaction mechanism in this research. Isotopic labelling experiments were also designed to ensure the existence of these intermediates.
