“…84 The initial oxidation was believed to be the rate-determining step, and catalysts such as Fe 2+ , Cr 3+ , Co 2+ or their complexes were essential to induce the production of oxygen-related radicals (HO_, O 2 _ À , et al). 49,50,[85][86][87] These oxygen-related radicals can also be produced at the cathode, inducing the cathodic ECL of luminol. 88,89 On the other hand, Au nanoparticles have been demonstrated to electrochemically catalyze oxygen reduction reactions, and were supposed to stabilize superoxide radicals through Au-O adsorption.…”

“…Since the amount of oxygen in ambient conditions is limited, hydrogen peroxide is necessary to promote intense luminescence, as oxygen is formed through the disproportionate reactions of hydrogen peroxide in basic conditions with iron compound catalysts. [48][49][50][51] Electrochemiluminescence (ECL), also called electrogenerated chemiluminescence, is chemiluminescence induced by electrochemical methods. An external light source and catalyst are not required; the electron transfer between the luminophores and co-reactants is induced by the applied potential.…”

Pd@Au core–shell nanocrystals with concave cubic shapes: kinetically controlled synthesis and electrocatalytic properties

et al. 2013

A new type of concave cubic Pd@Au core-shell nanocrystals is synthesized through a kinetically controlled growth process. Pd nanocubes of 56 nm are used as the inner core, and CTAC and Br(-) are used as the capping agent and selective adsorbent, respectively. A suitable ratio of HAuCl4 and cubic Pd seeds and the presence of Br(-) anions are critical to the growth of the concave cubic Pd@Au core-shell nanocrystals. The fast deposition rate on the corners of the cubic Pd seeds promotes the overgrowth of the Au outer shell along the <111> direction, leading to the formation of concave cubic nanostructures. The reduction process is monitored by the surface plasmon resonance spectra of the nanocrystals, and the extinction band became broader and red shifted as the nanocrystals became larger. The electrocatalytic properties of the concave cubic Pd@Au core-shell nanocrystals were investigated with the cathodic electrochemiluminescence reaction of luminol and H2O2. A possible electrocatalytic mechanism was proposed and analyzed.

“…The CL properties of luminol-H2O2-Cu(II) as well as peroxyoxalate-H2O2-dyestuff systems were examined in the presence of polymer particles with diameters of sub-micrometer order. 24,25 The enhanced CL was then observed through the reactions between chemical species on specific interfaces. We developed an FIA system equipped with a chemiluminescence detector using a mixed chemiluminescence reagent of luminol and 1,10-phenanthroline for the detection of metal ions and metal complexes.…”

Absorbance and fluorescence phenomena have been the most basic principles for the detection technique in an instrumental analysis. Also, chemiluminescence (CL), which has a profound relationship to their detection principles, has received much attention as an attractive detection technique. CL detection has the followings characteristics: highly sensitive, determinable over a wide range, easy to operate, and inexpensive apparatus and reagent. It has been used in FIA, HPLC, 1-4 and capillary electrophoresis. [5][6][7][8][9] Recently, CL detection is also estimated to be one of the most matched detection methods to the micro total analysis system (µ-TAS), because CL does not require any light source or spectroscopes. 10,11 The CL from synthetic compounds, including luminol, peroxyoxalate ester, ruthenium complex, lophine derivative, acridinium ester, and adamantyldioxetane compound, have been known for a long time, and many analytical applications of them have been reported. [12][13][14] The CL emitted by luminol is remarkably enhanced by a catalyst, such as metal ions. 15 This has been used for the determination of small amounts of metal ions and their complexes. The reaction of peroxyoxalate reagents, such as bis(2,4,6-trichlorophenyl)oxalate (TCPO) and H2O2, induces CL through energy transport to co-existing fluorescence compounds. 16 The peroxyoxalate CL reaction, which can detect fluorescence-labeled compounds, is useful and attractive in CL analyses, because the labeling for fluorescence methods has been widely investigated and the technique can be easily applied for CL detection using peroxyoxalate reagents.Tris(2,2′-bipyridine)ruthenium(II) ion (Ru(bpy)3 2+ ) has also been utilized as a CL reagent, where Ru(bpy)3 3+ , which is obtained electrochemically, oxidizes various organic amines. 17 The oxidant, Ru(bpy)3 3+, generally reacts best with tertiary, next with secondary, and with primary alkyl amines. The CL reaction was utilized to determine antibiotic compounds, like erythromycin and clindomycin, which both possess reactive tertiary amine groups. 18,19 However, compared to absorption and fluorescence detections, it is possible that CL detection lacks generality in its use. In order to solve this problem, many scientists have tried to synthesize novel CL reagents and to explore more effective analytical conditions. 2 New reaction phases or interfaces to change the CL property also been introduced into the CL reaction for a trace analysis of metal ions, H2O2, dyestuffs, etc. 20,21The local microenvironment in ordered surfactant assemblies, such as micelles, reversed micelles, and bilayer membranes, resulted in significant improvements in the analytical performance of CL reaction systems. For example, the CL mechanism in 1,10-phenanthroline (phen) oxidation during the catalytic decomposition of H2O2 was reported in 1982 by Fedorova et al., 22 and Ishii et al. found out micellar enhanced CL using phen-H2O2-cetyltrimethylammonium bromide (CTAB) system to determine Cu(II) at the sub-picogram level. 23 We stud...
