      abstract     = {Hydroalkoxycarbonylation of olefins has been considered to
                      be one of the most attractive methods to synthesize esters.
                      Controlling the regioselectivities of linear esters (L) and
                      branched esters (B) is a challenging project for researchers
                      working in this reaction. Although most of the attention has
                      been paid to control the regioselectivity through ligand
                      design in homogeneous catalytic systems, study in the area
                      is still limited. Herein, Ru-clusters/CeO2 is employed as a
                      heterogeneous catalyst for the hydromethoxycarbonylation of
                      styrene without any additives. After optimization of the
                      reaction conditions, the conversion of styrene is > $99\%$
                      with $83\%$ and $12\%$ regioselectivity of linear and
                      branched ester, respectively. By using different supports
                      (CeO2 (nanoparticle), CeO2-rod, and CeO2-cube), three
                      catalysts including Ru-clusters/CeO2, Ru/CeO2-rod, and
                      Ru/CeO2-cube are prepared and applied in the reaction.
                      Structural characterizations demonstrate that the L/B ratio
                      is related to the Ru size of supported Ru catalysts. Further
                      Raman characterization and NH3-TPD demonstrate that the
                      metal-support interaction and the concentration of oxygen
                      vacancy of the catalyst have a great influence on the Ru
                      size. The mechanism and kinetic analysis for this reaction
                      are also investigated in this work.},
