TLDR
Using 18O-enriched gaseous oxygen and bismuth molybdate catalysts, it has been shown that the oxygen atom in the product acrolein is derived from the oxide ions of the catalyst in the early stages of the reaction at low pressures as mentioned in this paper.About:

Characterization and Reactivity of Molecular Oxygen Species on Oxide Surfaces
M. Che,A.J. Tench +1 more
TL;DR: This chapter discusses the characterization and reactivity of mononuclear oxygen species on oxide surfaces and there is evidence from the examples for some of the species that are stable at much higher temperatures and may play an important role in catalytic reactions.

Phase Cooperation and Remote-control Effects in Selective Oxidation Catalysts
Lu-Tao Weng,Bernard Delmon +1 more
TL;DR: In this paper, the authors discuss the possible reasons why these phases cooperate (act synergetically) and different interpretations of the synergy is often due to remote control and discuss the various modifications of the acceptor brought about by spill-over oxygen.
