Ii. Research activities
Influence of polymer addition on the nanostructuring of NiMoS catalysts

The addition of a polymer during the synthesis of MoS2 catalysts promoted by nickel, not only makes it possible to considerably increase their specific surface area but also to reduce the stacking and length of MoS2 sheets. Research themes Collaborations & Contracts Research themes

Synthesis of nanostructured chalcogenides by soft chemistry

The attraction of chalcogenide synthesis by soft chemistry is not only to develop new families of chalcogenide materials but also to master the multi-scale structuring by adding adequate structuring and in particular polymers. The chalcogenides thus obtained find applications in many fields and in particular in catalysis or electrochemistry.

As part of several financings and in particular an ANR project (PASSCATA 2016-2020) we have been able to develop bulk catalysts of the NiMoS type (MoS2 promoted by nickel). A collaboration with the D2 department allowed us to study the multi-scale structuring of catalysts using commercial or custom synthesized polymers. During this study we developed a method of synthesis "one-pot" of the promoted catalysts. The introduction of polymers during synthesis allows, for example, to considerably increase the specific surface area of materials but also to reduce the stacking of MoS2 sheets. In addition, the materials obtained revealed very interesting catalytic activities during hydrotreating reactions of model molecules, especially for those prepared by our new synthesis method.

As part of a new collaboration within our department and with departments D2 and D3, we are using our know-how on the synthesis of MoS2 to offer new electrodes for sodium batteries.
