Abstract Electrochemical seawater splitting faces competing chlorine evolution reactions and corrosion, proposing significant obstacles to commercial applications. In this work, a feasible strategy is developed for the simultaneous oxidation of SO 4 2− CoFe LDH form an intercalation /CoFe LDH, which achieves excellent OER performance (265.2 mV@100 mA cm −2 ) satisfactory stability (1000 h@500 ). The presence found enhance intrinsic activity reduce corrosion tendency LDH. situ Raman selected area electron diffraction results demonstrated that are simultaneously generated inserted into interlayer. DFT calculations further confirmed insertion reduced Cl − adsorption, improved selectivity. Finally, in flow AEM electrolyzer, Pt/C system exhibited voltage only 2.264 V at 500 achieved stable operation natural 150 h. working efficiency as high 55.0% with price per GGE H 2 low $1.211, promising wide range

Enhancing biohydrogen production: a comparative analysis of utilization of Jerusalem artichoke and bakery waste by dark fermentation

Renewable Energy, Год журнала: 2024, Номер 235, С. 121292 - 121292

This study investigates the potential of using Jerusalem artichoke (JA) and bakery waste (BW) for biogas biohydrogen production through dark fermentation. The experiment included four series with different ratios JA to BW (100:0, 0:100, 50:50, 75:25) under mesophilic conditions at 39°C. highest (1.46 L/L.d) hydrogen (0.508 was achieved alone. A synergistic effect observed 50:50 mixture, resulting in volatile fatty acids (VFA), which reached up 22252 mg/L. shows advantages combining these substrates optimized energy production. Spearman rank correlation analysis identified ammonium-nitrogen (N-NH4) as most influential factor showed a strong positive butyric acid/acetic acid (B/A) ratio (ρ = 0.85, p < 0.001). indicates that maintaining optimal levels is critical maximizing yields. In addition, total solids (TS) (VS) moderate correlations specific VFAs, indicating their significant role VFA dynamics. These results highlight importance substrate optimization stable fermentation sustainable efficient
