Towards sustainable urea electrooxidation: A thermodynamic and green chemistry evaluation of alternative pathways

Electrochemical oxidation of urea is a promising pathway in sustainable hydrogen production, yet the efficiency and environmental impact of alternative reaction routes remain poorly characterized. This dataset compiles thermodynamic and green chemistry parameters for seven distinct urea electro-oxidation pathways under alkaline conditions. Standard enthalpy and entropy values for all reactants and products were calculated using literature thermochemical data (Table_S1.csv). Standard electrode potentials for five key half-reactions (5)–(9) were derived and compared with values reported in the literature (Table_S2.csv). In addition, four figures (Figure_S1–S4.png) visualize key comparative metrics across the pathways: open-circuit voltage (OCV), E-factor, entropy change (ΔS), and enthalpy change (ΔH). These data allow for cross-pathway benchmarking based on both energy and sustainability metrics. The dataset can be reused in studies involving green electrochemical synthesis, hydrogen energy systems, and lifecycle modeling of urea-involved energy processes.
