Abstract

Nuclear magnetic resonance (NMR) and total neutron scattering techniques are established methods for the characterisation of liquid phases in confined pore spaces during chemical reactions. Herein, we describe the first combined total neutron scattering - NMR setup as a probe for the catalytic heterogeneous reduction of benzene-d6 with D2 in 3 wt% Pt/MCM-41.

Highlights

Nuclear magnetic resonance (NMR) and total neutron scattering techniques are established methods for the characterisation of liquid phases in confined pore spaces during chemical reactions
Modelling of reacting mixtures requires detailed compositional information at a given point in time, which cannot be obtained from total neutron scattering or ex situ sampling methods due to sensitivity, radiation and experimental setup restrictions
This paper describes the development of a coupled total neutron scattering – NMR (NeuNMR) setup that enables a better understanding of the liquid phase of heterogeneously catalysed systems by combining the information from both techniques
