      abstract     = {The Cu-catalyzed electrochemical CO2 reduction enables the
                      conversion of greenhouse gas emissions to fuels or platform
                      chemicals with prospects of storing intermittent energy from
                      renewable sources. While current research in tuning catalyst
                      activity and product selectivity is often mired in finding
                      electrode engineering solutions, the importance of
                      electrolyte engineering is mostly overlooked. This study
                      presents a method for measuring local pH profiles in
                      electrode proximity and correlating them to cation-induced
                      buffering effects. Magnetic resonance imaging (MRI)
                      techniques were applied to evaluate the local pH values
                      using spatially resolved 13C resonances of the
                      CO2/HCO3–/CO32– equilibrium. The buffering effect of
                      cation hydrolysis is substantiated by local shifts of the
                      23Na resonance of Na+ in the NaHCO3 electrolytes. Steeper
                      local pH gradients, compared to experiments with KHCO3,
                      account for increased selectivity for acetate formation from
                      the solution-based reaction. Proven itself capable of
                      elucidating the effect of cations on local pH values, our
                      presented method supports tailoring the
                      electrode–electrolyte interface to selectively generate
                      value-added products.},
