2019-06-10: Progress on Solid oxide electrolysis cells for CO2 electroreduction Our group revealed the negative effect of Ni doping into SrFe1.5Mo0.5O6-d as cathode for CO2 electroreduction in solid oxide electrolysis cells. Ni doping decreases the perovskite stability under electroreduction conditions, Fe and Ni cations in the B-site are reduced to metal nanoparticles and SrCO3 forms on the surface of the perovskite. This work has been published in Journal of Energy Chemistry, 2019, 36, 87-94.

2018-03-09: Progress on Selective Oxidation of Light Alkanes Our group investigated the effect of V-containing precursors on the structure of Cs-salt phosphomolybdates and catalytic performance of isobutane oxidation. Three effects can be traced back to the precursors: surface acidity, the location of V species and ratio of V4+/V5+ and Mo5+/Mo6+ redox couples. This work has been published in Applied Catalysis A: General, 2018, 556, 104-112.
