The electrocatalytic performance of the nanosheets is studied by density functional theory (DFT) calculation and the product selectivity is justified by the reaction barrier in both hydrogen evolution and CO₂ reduction reactions.

Combined electron microscopy techniques are used to reveal atomically resolved chemical and crystal properties of BaTiO₃ (BTO) and strontium doped BTO nanoparticles. In contrast to the powder X-ray diffraction (PXRD) results referring to the structural transition from tetragonal to cubic phase associated with increasing Sr doping amounts, microscopic data validate the co-existence of tetragonal unit cells and cubic unit cells in the BTO nanoparticles and increasing compositional and microstructural inhomogeneities along with the higher Sr doing amounts.
