In the field of Applied Sciences, Materials Physics and Environmental Engineering, sluggish kinetics and poor selectivity in CO2 electro-reduction hinder industrial carbon capture and valorization. This empirical investigation systematically examines Atomically Dispersed Nickel-Nitrogen-Carbon Catalysts for Electrochemical CO2 Reduction to Syngas through a multi-stage experimental methodology and rigorous quantitative analytical framework. Utilizing pyrolysis of zinc-nickel zeolitic imidazolate frameworks, zero-gap membrane flow cell testing, and in-situ ATR-FTIR spectroscopy, data were gathered across multiple operational cycles and validated against established international benchmarks. The statistical and computational results reveal that the Ni-N-C catalyst delivered tunable syngas ratios with CO Faradaic efficiency surpassing 92% at 300 mA/cm2 over 150 hours of continuous operation. Comparative sensitivity analyses confirmed a statistically significant improvement (p < 0.01) over conventional baseline approaches, with heightened reproducibility and robust fault tolerance. These comprehensive findings provide actionable theoretical insights and practical implementation guidelines for industrial carbon capture, utilization, and storage (CCUS) and sustainable chemical synthesis. Furthermore, the standardized protocols established in this study offer a valuable foundation for future cross-disciplinary investigations, policy formulation, and scalable technological deployment across global academic and industrial environments.
