Unveiled the Structure-Selectivity Relationship for Carbon Dioxide Reduction Triggered by Bi-Doped Cu-Based Nanocatalysts.

To investigate synergistic effect between geometric and electronic structures on directing CORR selectivity, water phase synthetic protocol and surface architecture engineering strategy are developed to construct monodispersed Bi-doped Cu-based nanocatalysts. The strongly correlated catalytic directionality and Bi dopant can be rationalized by the regulation of [*COOH]/[*CO] adsorption capacities through the appropriate doping of Bi electronic modulator, resulting in volcano relationship between FE/TOF and surface EVBM values. Spectroscopic study reveals that the dual-site binding mode ([Cu─μ─C(═O)O─Bi]) enabled by CuBi motif in single-phase CuBi nanocatalyst drives CO2-to-CO conversion.

Ring-Opening Polymerization of ε-Caprolactone and Styrene Oxide-CO Coupling Reactions Catalyzed by Chelated Dehydroacetic Acid-Imine Aluminum Complexes.

A series of chelated dehydroacetic acid-imine-based ligands ~ was synthesized by reacting dehydroacetic acid with 2-t-butylaniline, ()-1-phenyl-ethylamine, 4-methoxylbenzylamine, and 2-(aminoethyl)pyridine, respectively, in moderate yields. Ligands ~ reacted with AlMe in toluene to afford corresponding compounds (), (), (), and (). All the ligands and aluminum compounds were characterized by IR spectra, H and C NMR spectroscopy.
