In-situ electrochemical transformation of F-modified metallic bismuth for highly-efficient CO2 electroreduction and Zn-CO2 battery
Wenbo Wu
et al.
Jun 13, 2024
Electrocatalytic CO2 reduction (ECO2R) to produce formate is one of the essential routes for CO2 upgrading. Herein, the bismuth oxyfluoride (BiOF) material is firstly rationally designed as a precursor to derive the F-modified Bi catalyst (FD-Bi) for ECO2R. The FD-Bi catalyst achieves more than 90 % Faradaic efficiency of formate (FEformate) over a wide potential range of −0.5 ∼ -1.2 V vs. RHE. By coupling in-situ Raman and infrared spectroscopy, the transformation of BiOF to FD-Bi and the formation of key *OCHO intermediates have been revealed. Density functional theory (DFT) calculations further confirm the optimized electronic structure and the favorable adsorption energies of intermediates on F-modified Bi catalyst. In a coupled system for the co-production of formate, a high FEformate of 159.1 % can be realized at a small cell voltage of 1.9 V. In addition, Zn-CO2 battery equipped with FD-Bi delivers a high power density of 2.68 mW·cm−2 and superior stability.

Pt-decorated spinel MnCo2O4 nanosheets enable ampere-level hydrazine assisted water electrolysis
Xuhui Ren
et al.
Jul 14, 2024
Coupling hydrazine oxidation reaction (HzOR) with hydrogen evolution reaction (HER) has been widely concerned for high efficiency of green hydrogen preparation with low energy consumption. However, the lacking of bifunctional electrodes with ampere-level performance severely limits its industrialization. Herein, we put forward an efficient active site anchored strategy for MnCo

Oxygenate-induced structural evolution of high-entropy electrocatalysts for multifunctional alcohol electrooxidation integrated with hydrogen production
Jinfeng He
et al.
Jul 16, 2024
High-entropy compounds have been emerging as promising candidates for electrolysis, yet their controllable electrosynthesis strategy remains a formidable challenge because of the ambiguous ionic interaction and codeposition mechanism. Herein, we report a oxygenates directionally induced electrodeposition strategy to construct high-entropy materials with amorphous features, on which the structural evolution from high-entropy phosphide to oxide is confirmed by introducing vanadate, thus realizing the simultaneous optimization of composition and structure. The representative P-CoNiMnWVO
