Ce-Doped NiSe Nanosheets on Carbon Cloth for Electrochemical Water-Splitting

“…Urea was used as a hydrolyzing agent, and NH 4 F works as a growth-regulating agent. , Initially, y NH 3 ·H 2 O reacted with Ni 2+ salt, and the [Ni­(NH 3 ) y ] 2+ complex was formed. In the next step, the [Ni­(NH 3 ) y ] 2+ complex reacted with Na 2 SeO 3 and N 2 H 4 in the presence of OH – ion and converted into the black-colored Ni 0.85 Se sample . During Ce doping, Ce 0.1 Ni 0.85 Se was developed without any change in the chemical reaction, except for ammonium ceric nitrate being added.…”

The XRD analysis of Cedoped Ni(OH) 2 /NiOOH was performed, which confirms the presence of Ni(OH) 2 and NiOOH in the system (Figure S2).…”

Synthesis and Characterization of CuO@PANI composite: A new prospective material for electrochemical sensing

“…In addition, the high surface area [11], antibacterial activity [12] and drug delivery [13] make such materials effective substrate for fabrication of novel composites material for various fields [14][15][16]. In addition, Nanomaterials and their nanocomposites with unique atomic thickness are promising materials for various applications including tissue engineering [16], energy storage [17,18], water related applications [18] and catalytic industries [20][21][22] due to their outstanding properties such as high mechanical strength, large surface area, good chemical and thermal stability, ease of functionalization, and hydrophilic surface.For instance, Benmoussa et al, proposed a novel electrochemical biosensor to detect cancer biomarker (lactic acid) based on organic-inorganic composite coupled with a molecularly imprinted polymer to create a highly sensitive and selective electrochemical biosensor where a limit of detection around 0.726 μM has been determined [14]. Hence, The NPs-modified electrode enhanced signal responsiveness, sensitivity, and repeatability [23][24][25][26][27], and it has several bioscience applications.Furthermore, the characteristics of composite materials are determined by the morphology of the phases, which must be regulated across many length scales [25][26][27][28].…”
