Data from: 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.
