This dataset focuses on the regulation mechanism and performance optimization of CO₂ reduction for multi-carbon alcohol production. Developed based on supported single-atom catalysts and copper-based catalysts, this dataset targets the efficient generation of CO (key intermediate), carbon-carbon coupling to multi-carbon products, and regulation of the subsequent multi-carbon alcohol formation pathway, and it contains 14 sub-datasets. It mainly includes the design and synthesis methods of three types of catalysts: single-atom catalysts that can efficiently convert CO₂ to CO at industrial-grade current densities, copper-based catalysts with high carbon-carbon coupling activity, and copper-based catalysts that can produce multi-carbon alcohols with high selectivity; as well as their physicochemical characterization, performance evaluation and catalytic mechanism research. The dataset records SEM, TEM, XPS and XRD characterization results of catalytic materials and electrode structures such as nickel single-atom catalysts and copper-based binary catalysts; the electrocatalytic CO₂ reduction activity and selectivity of different catalytic electrodes; theoretical simulations and in-situ characterization of the catalyst structure and catalytic process; and analyses of the mechanism of electrocatalytic CO₂ reduction for multi-carbon alcohol production and catalyst design strategies. The main instruments used include electrochemical workstation (CHI660E), scanning electron microscope (HITACHI S-4800), high-resolution transmission electron microscope (JEOL JEM-2100F), X-ray diffractometer (Model D/MAX2500, Rigaka) and X-ray photoelectron spectrometer (Thermo Scientific ESCALab 250Xi), among others.
