NMR spectroscopy is one of the techniques routinely used to characterize nanoporous materials such as zeolites, carbons, MOFs and COFs. It is also used to study mass transfer phenomena that enable fundamental physicochemical processes, such as catalysis or (electro) chemical energy conversion and storage.
The aim of this workshop - organised by Muslim Dvoyashkin and DECHEMA - is to familiarize doctoral researches and postdocs with the latest experimental NMR-based approaches and methods used to characterize this class of materials and to investigate molecular or ionic transport phenomena. In addition, the participants will obtain the opportunity to exchange their own experiences and discuss with the speakers.
Registration is limited and will be handled by "First come, first serve".

“Introduction into Solid-State NMR Spectroscopy – From Chemical Shifts to Distance Measurements in porous Solids”
Among other techniques solid-state nuclear magnetic resonance spectroscopy (ssNMR) is a powerful and flexible tool for deriving structure information on porous materials.1 ssNMR is able to identify chemical building units and simultaneously probe their homo- and heteronuclear through-bond and through-space connectivities, orientation correlations as well as distances up to a few nanometres. The tutorial will first explain important fundamental aspects of ssNMR and then intents to provide an overview of important strategies to probe structural properties of frameworks and unravel host-guest interactions. Emphasis will be on dipolar recoupling. Based on some illustrative examples, the tutorial will show how to select the best NMR experiments and will explain how to set up the spin systems needed for the analysis of the experimental data.

“Introduction to Solid-state Dynamic Nuclear Polarization”
The tutorial will introduce the analysis technique of solid-state dynamic nuclear polarization (solid-state DNP). This technique uses the three order of magnitude higher electron spin polarization and transfers it into nuclear spin polarization, which drastically boosts sensitivity of solid-state nuclear magnetic resonance experiments. The talk will introduce this technique including the basic theoretical background and covers various practical aspects of this technique. Finally, specific examples for solid-state DNP NMR studies of porous materials including immobilized catalysts, technical catalysts, metalorganic frameworks, nanoparticles and paper materials will be presented.
11:00 - 12:00
Prof. Dr. Igor Koptyug (International Tomography Center, Novosibirsk, Russia)
“NMR Spectroscopy and Imaging of Catalytic Hydrogenation in Heterogeneous Systems”
This tutorial will explain the key challenges for spectroscopic and imaging operando studies of heterogeneous catalysts and model reactors by NMR-based techniques, and show that such applications, while challenging, are feasible and can be very informative. In particular, the use of parahydrogen with various catalyst types (supported metals, immobilized metal complexes, single-site catalysts, etc.) can result in a major boost in sensitivity, thus providing access to both mechanistic details and spatial dynamics of products distribution.
12:00 - 13:00 Lunch Break
13:00 - 15:00
Networking with wonder.me
For the interactive session in wonder, participants are invited to prepare thematically matching questions from the research work and address them to the speakers. As wonder also offers the possibility of screen sharing, participants can, if preferred, also present the questions on a maximum of one slide.
