Offer Description
Objective
The Doctoral Candidate (DC) will develop poly(ionic liquid)s (PILs)-based composites as cathode catalysts for accelerating CO2 conversion in Na-CO2 batteries. The purpose is to combine aminated PILs and non-critical transition metal catalysts for activating and catalyzing CO2 redox conversion at the Solid-Liquid interfaces. The structure-activity relationship between groups in polymers, metal centres and electrochemical CO2 reduction/evolution performances will be studied by FTIR, NMR, CO2 adsorption/desorption, TEM (cooperation with DC3). The chemical environments of metal sites will be clarified for ex-situ and operandoXAS (cooperation with DC11). The latter will be combined with DFT calculations to unveil the CO2 conversion mechanism. Swagelok-type cells will be assembled to elucidate the electrochemical performance, including the CV plots for determining redox reactions, GDC profiles for cycle stability and rate capability.
Expected results
(1) Improving the performance of Na-CO2 batteries achieving high-efficient CO2 fixation and utilization, and energy supply simultaneously; Training research skills, including polymer and catalysts synthesis, as well as characterization of CO2 conversion in batteries.
(2) Targets at cathode performance: <0.5 V at 0.5 mA g-1 for CRR/CER overpotentials. 1000 cycles at 0.5 mA g-1 within 1000 mAh g-1 for cycle stability.

Scientific background
The climate targets set by the EU with the goal of climate neutrality by 2050 require a transformation of all sectors of the economy towards the use of renewables-based electricity, calling for joined forces between EU countries in order to achieve a more resilient energy system. In the e-ChemIn we are united by the idea of applying a new paradigm in designing energy devices, which shifts the current approach of creating individual materials towards engineering electrochemically ACTIVE MATERIALS INTERFACES. Working together we will: 1) design multiple sets of electrochemical interfaces using renewable, abundant, and circular materials and optimize them for new generations of energy conversion and storage devices. Created lab-scale prototypes which outperform characteristics of current benchmarks and will be ready for further developments at high TRLs (5-9); 2) develop multimodal approaches for the characterization of interfaces operando at the nanoscale, providing unprecedented insights into interfaces in action and making the characterization of active interfaces accessible to the broader scientific community; 3) successfully establish processes for the recovery of critical raw materials from end-of-life devices and apply them at the industrial scale.
