Dataset for: Impact of Ion Irradiation on the Electrochemical Catalytic Activity of Carbon Nanospheres for Efficient Ammonia Generation

This dataset contains the raw and processed experimental data supporting the manuscript Impact of Ion Irradiation on the Electrochemical Catalytic Activity of Carbon Nanospheres for Efficient Ammonia Generation. The dataset includes structural, morphological, textural, thermal, spectroscopic, and electrochemical characterization of pristine and ion-irradiated carbon nanospheres (CNSs) used as metal-free electrocatalysts for the electrochemical nitrogen reduction reaction (NRR). Carbon nanospheres were modified by controlled implantation of B+, N+, and Ne+ ions at two implantation durations (7 h and 14 h), enabling systematic investigation of defect engineering on catalytic activity. The dataset contains Raman spectroscopy, SEM images, BET adsorption-desorption measurements, thermogravimetric analysis (TGA/DTG), electrochemical measurements (LSV, CV, chronoamperometry), ammonia yield calculations, Faradaic efficiency data, and supporting characterization used to generate all figures presented in the manuscript and Supplementary Information.
