Hierarchical CuO nanochains: Synthesis and their electrocatalytic determination of nitrite

A promising electrochemical sensing platform based on a silver nanoparticles decorated copolymer for sensitive nitrite determination

“…detection limit and high sensitivity at the ESP, GC/Ag-P(MMAco-AMPS) is better than other reported works for the oxidative determination of NO 2 À (Table 1). 21,22,[39][40][41]44,[46][47][48][49][50][51][52][53][54][55][56][57][58][59][60][61][62] Additionally the observed detection limit, 0.2 mM (0.009 mg L À1 ) using the present ESP is very much lower than the maximum permissible limit of NO 2 À (2.17 mM (0.1 mg L À1 )) 63 in drinking water. The World Health Organization (WHO) recommends a guideline value of 65 mM (3 mg L À1 ) and a provisional guideline value of 4.3 mM (0.2 mg L À1 ) for short-term and long-term exposures, respectively.…”

Nanostructured copper oxide semiconductors: a perspective on materials, synthesis methods and applications

“…207 They found that the nucleation and growth kinetics of CuO nanoparticles can be tuned by varying the processing parameters including the volume ratio of DMAC and water, increasing the temperature of the solution and the molar ratio of Cu 2+ and OH À . 207 Apart from nanoparticles, chemical precipitation synthesis has commonly been used to synthesize different morphologies of CuO including nanowires, [208][209][210] nanoribbons, 211 ower-like, 212,213 hierarchical nanochains 214 and nanosheets. 215,216 A recent comprehensive review on nanostructured CuO via the solution-based chemical precipitation technique is found elsewhere.…”

A nanomaterial composed of cobalt nanoparticles, poly(3,4-ethylenedioxythiophene) and graphene with high electrocatalytic activity for nitrite oxidation

“…Since electrochemical oxidation of nitrite typically involves a large overpotential at the surfaces of the un-modified carbon electrodes, the detection of nitrite tends to suffer from interference by other more easily oxidized compounds. To overcome this problem, various modified electrodes have been constructed such as polymer film modified electrodes [9], nanoparticles modified electrodes [10,11], surfactant modified glassy carbon electrode [12], and carbon nanotube modified electrodes [8,13,14].…”
