      abstract     = {Visible light-driven C–C bond formation to produce
                      C2-based liquid fuel selectively from CO$_2$ is of great
                      interest and remains a challenging task due to uphill
                      electron transfer kinetics. Herein, we have developed
                      [Ru(bpy)$_2$]$^{2+}$-grafted UiO-66-bpydc Ce-MOFvia
                      post-synthetic modification to harvest visible light based
                      on MLCT $(RU_{d\pi}^{II} \to \pi_{bpy}^*)$ transition. The
                      employment of Ru-grafted Ce-MOF facilitates fast electron
                      transfer due to the vacant low-lying 4f orbital of
                      Ce$^{IV}$, which was realized from ultrafast transient
                      absorption (TA) spectroscopy, XANES, and in situ UV-vis
                      spectroscopy. The synergistic effect of facile electron
                      transfer and concomitant accommodation of two CO$_2$
                      molecules in the proximal defect-site in Ce$^{IV}$ leads to
                      facile C–C bond formation via COOH* coupling to yield
                      acetic acid. The catalytic assembly produces 1133 μmol
                      g$^{−1}$ of acetic acid with an impressive rate of 128
                      μmol g$^{−1}$ h$^{−1}$, suppressing the formation of
                      other C1-based carbonaceous products in water (with
                      selectivity 99.5\%, apparent quantum yield (AQY) = 0.93\%).
                      A detailed DFT calculation has been performed to understand
                      the mechanistic pathway of C–C bond formation, and the
                      generation of different surface-adsorbed intermediates was
                      further supported by in situ diffuse reflectance infrared
                      Fourier transform (DRIFT) spectroscopy.},
