The uncontrollable electrochemical reduction reconstruction, leading to the destruction of well-defined structure and subsequent low durability, is main obstacle catalytic performance Bi-based composites toward CO2 reaction (eCO2RR). Herein, we address this issue through construction a novel β-Bi2O3/Bi2O2CO3 composite, which can resist reconstruction materials metallic Bi during eCO2RR process by modulating more alkaline microenvironment that facilitates formation new Bi-O bonds. synergistic interactions directional electron transfer between β-Bi2O3 Bi2O2CO3 components, together with stable composite structure, result in its superior activity selectivity for formate production high faradaic efficiencies (FEs) over 94% from -0.7 -1.1 V, remarkable durability maintenance 80% FE after continuous electrocatalysis 720 h. This work sheds light on designing advanced high-performance nanomaterials other practical applications.

Abstract Here, we demonstrate hydrothermally grown bismuth sulfide (Bi 2 S 3 ) micro flowers decorated nickel foam (NF) for electrochemical detection of melamine in bottled milk samples. The orthorhombic phase Bi is confirmed by the detailed characterization x-ray diffraction and its high surface area flowers-like morphology investigated via field emission scanning electron microscope. Furthermore, chemical oxidation state binding energy /NF analyzed photoelectron spectroscopy studies. sensor exhibits a wide linear range from 10 ng l −1 to 1 mg superior sensitivity 3.4 mA cm −2 using differential pulse voltammetry technique, with lower limit (7.1 ). as-fabricated highly selective against interfering species p-phenylenediamine (PPDA), cyanuric acid (CA), aniline, ascorbic acid, glucose (Glu), calcium ion (Ca 2+ Real-time analysis done standard addition method shows an excellent recovery percentage ̴ 98%. sensor’s mechanism studies reveal that interacts strongly molecules through hydrogen bonding van der Waals forces, resulting significant change electrical properties while 3D skeletal Nickel as substrate provides stability, enhances catalytic activity providing more number /of active sites facilitates rapid transfer. work presented here confirms high-performance electrode can be used other biomolecules clinical diagnosis biomedical research.

Abstract This study explores the impact of nickel (Ni) doping bismuth ferrite (BiFeO 3 ) thin film synthesis by spray pyrolysis method. The structural and morphological shows that films are slightly amorphous with granular morphology. Investigated supercapacitive behavior synthesized material using cyclic voltammetry, galvanostatic charge‐discharge, electrochemical impedance spectroscopy. capable storing a 253.31 F/g capacitance at 10 mV/s scan rate introducing into process, we obtained 312.12 rate. good stability after 91000 cycles. It is also observed no changes were made Ni BiFeO films. significant improvement in was displayed via methods indicating its potential for use supercapacitor applications.
