Facile Synthesis of Silver-Doped Copper Selenide Composite for Enhanced Electrochemical Detection of Ecological Toxic Nitrobenzene

The impact of Ni and Zn doping on the thermal durability and thermoelectric variables of pristine CuSe nanoparticles

“…42,43 The XPS profiles of Se 2d for all samples exhibit two photoelectron bands with binding energy values of 54.2 eV and 55.0 eV, designated as Se 2d 5/2 and Se 2d 3/2 , respectively, known as standard peaks of Se. 2–42,44 The identical patterns of both of the Cu 2p peaks and Se 3d peaks for each nanoparticle indicate the existence of CuSe.…”

“…Within the realm of existing literature, numerous investigations delved into transition metal-doped CuSe materials in both nanocrystal and thin film formats. [24][25][26] However, no scholarly discourse has reported the exploration of 5% and 10% doping levels for Ni and Zn in CuSe nanoparticles. As a consequence, the authors intended to synthesize and examine Ni and Zn-doped CuSe nanoparticles.…”

Electrochemical detection and catalytic reduction of nitrobenzene using a bimetallic NiS2/Fe3S4 magnetic heterostructure: an innovative approach for environmental remediation

“…The United States Environmental Protection Agency (USEPA) has also set a limit on the concentration of NB in wastewater, which cannot be more than 20 ppb. 15,16 Routine monitoring of NB in water systems is the only reliable preventive method to avoid long-term harm to human and animal health. Traditional methods for nitrobenzene detection, such as gas chromatography, 17 high-performance liquid chromatography, 18 nuclear magnetic resonance, 19 and fluorescence spectroscopy 20 often involve complex sample preparation and time-consuming processes.…”
