The electrochemical CO2 reduction reaction (CO2RR) is a promising strategy to alleviate excessive levels in the atmosphere and produce value-added feedstocks fuels. However, synthesis of high-efficiency robust electrocatalysts remains great challenge. This work reports green preparation surface-oxygen-rich carbon-nanorod-supported bismuth nanoparticles (SOR Bi@C NPs) for an efficient CO2RR toward formate. resultant SOR NPs catalyst displays Faradaic efficiency more than 91% formate generation over wide potential range 440 mV. Ex situ XPS XANES Raman spectroscopy demonstrate that Bi-O/Bi (110) structure pristine can remain stable during process. DFT calculations reveal facilitate formation *OCHO intermediate. provides approach development Bi-based catalysts offers unique insight into exploration advanced electrocatalysts.

Electrocatalytic overall water splitting (OWS), powered by a renewable energy source, is promising strategy for hydrogen production. However, the OWS system usually requires large consumption due to sluggish kinetics of anodic oxygen evolution reaction. Herein, we fabricated PtCu nanoalloy (PtCu-NA) through template-assisted method and evaluated its bifunctional activities both reaction (HER) in 1 M KOH hydrazine oxidation (HzOR) + hydrazine. Remarkably, interplanar crystal spacing PtCu-NA was larger than that standard closer Pt, which can be attributed synthesis method. Thus, as-prepared needs low overpotentials 224 668 mV drive HER HzOR at 100 200 mA cm–2, respectively, are much better those commercial Pt/C (453 1081 mV). After coupling together, (OHzS) cell small voltage 0.666 V deliver cm–2 hydrazine, outperforming (0.792 V). Impressively, assembly OHzS could run stably more 110 h. These performances regulation structure alloy synergistic effect between Pt Cu.
