Abstract Single‐atom catalysts (SACs) anchored on defective supports offer exceptional catalytic efficiency but face challenges in stabilizing isolated metal atoms and optimizing metal‐support interactions. Here, a defect‐driven strategy is reported to construct 3D dendritic SAC comprising interwoven ultrathin TiO 2 nanowires (NWs) with abundant oxygen vacancies (OVs) that stabilize atomically dispersed cobalt (Co) sites. Using hydrothermal synthesis followed by acid etching calcination, Ti─Co─Ti motifs are engineered at OVs site. The architecture provides multiscale porosity charge transport, achieving syngas production rates of 28.4 mmol g −1 ·h (CO) 13.9 (H ) high turnover frequency (TOF) 10.6 min , surpassing many other state‐of‐the‐art Co‐based SACs. In situ Raman electron paramagnetic resonance (EPR) analysis reveal consumption during Co anchoring, while density functional theory (DFT) validates redistribution from Ti Co, enabling efficient transfer inducing strong electronic interactions enhance CO adsorption activation. results highlight the interplay between atomic‐scale coordination environments macroscale architectural order harnessing potential SACs 1D NWs.
