PhD position (M/F) – fixed-term: Synthesis of selective small pore nanosized zeolites (link)
The growth process of low silica and low alumina containing nanosized zeolites from colloidal suspensions will be explored with and without organic structural directing agents. The broad technical objective of the program is to elaborate a versatile strategy to analyze the nanozeolites with advanced methods behind the classical approaches for characterization. The in-situ experimental analyses will be complemented by theoretical study using the precise multiscale modelling of interfacial phenomena occurring at gas-solid and liquid-solid interfaces.
Strategic development of nanomaterials exploring new routes: green synthesis of nanomaterials with on-demand properties.
The PhD will be in charge of the development of novel methodology for synthesis of nanosized small pore zeolites. A particular attention will be paid on the new properties related with the versatility in chemical compositions, framework structures and extra framework cations. The adsorption and separation of CO2 and O2 will be controlled by “cage entry” and “guard cations” located in the secondary building units of zeolites.
Post-doctorat (H/F) :Understanding the transition from random- to long- range crystalline order in novel operational nanomaterials (link)
Missions
Synthesis and development of new methodology for characterization of nanoporous material (zeolites and zeotypes) with spectroscopic techniques. Evaluation of the zeolites and nanoporous materials in CO2 separation, cycling, gas capture and target gas delivery (biomedicine).
Activities
The Post Doc will be in charge of the development of novel methodology toward understanding the transition from random to long- range crystalline order of porous materials. A particular attention will be paid on the new structures and scale up of the synthesis. The formation of the very first secondary building units, followed by the formation of cages and/or channels, their interconnection, crystal surfaces and terminations will be studied. The bulk and surface properties of nanozeolites related to the diffusion in small pores and cages will be thoroughly investigated. In-situ NMR spectroscopic characterization will be performed under real synthesis conditions. The unique facilities in my laboratory provide all the necessary analytical methods for characterization of nanosized zeolites (in-situ IR, NMR, Raman, DLS, XRD).
