Abstract

Understanding the mechanisms that underlie photocatalytic hydrogen evolution requires the combination of different approaches. In this chapter, we delve into isotopic substitution and labeling as one of such approaches. It allows to pinpoint the route of individual atoms (e.g. O in TiO 2 and their incorporation into CO 2 ), to evaluate rate-determining steps in reaction mechanisms (and identify bottlenecks), and to apply techniques that would otherwise be unusable (e.g. 17 O electron spin resonance). We present a set of interesting literature examples in which the labeling was performed either in the material itself, in the solvent, or in the substrate molecules. It is our hope that this chapter will inspire researchers to find new applications of isotopic substitution and that it will bring this powerful tool to more widespread use.
