Dual-ligand-driven morphology control: constructing spindle-shaped Ni single-atom catalysts for high-efficiency CO2-to-CO conversion and Zn-CO2 battery applications

The data were generated between July 2025 and July 2026, and the spatial coverage is Shanghai, China. The data collection and generation processes strictly followed scientific protocols: first, an experimental scheme was designed to prepare catalysts with target performance; second, the electrochemical performance of the prepared catalysts was tested; and finally, the catalysts were characterized using various analytical techniques.

The main equipment used during the processing includes an electrochemical workstation (Reference 600+), a gas chromatograph (GC-2014), and a high-temperature tube furnace (SK-4-12). The dataset contains multiple data files, which are listed in the accompanying data list. All data are stored in common formats (e.g., spreadsheets and text files), and each file is clearly described in the data list.
