“…The broad diffraction peaks at about 25º for all samples can be indexed as (002) diffraction plane of the hexagonal phase graphite (JCPDS No. 41-1487) [20]. The broad pattern of diffraction peaks indicates the poor graphitization degree for NCM-700Ni and NCM-800.…”

Nitrogen doped (N-doped) carbon materials (NCMs) are generally used as electrode materials, and seldom used as catalysts in chemical reaction. In this work, NCMs were prepared by high-temperature pyrolysis using monosodium glutamate as sources of both carbon and nitrogen, magnesium acetate as a porogen, and nickel hydroxide as a graphitization catalyst. The catalytic performance of NCMs was investigated in the reduction of 4-nitrophenol (4-NP) with potassium borohydride at 30 ºC. As metalfree catalysts, all of the NCMs can catalyze the reaction. The graphitization degree and N-doped amount of NCM have a great influence on the catalytic activity. The NCM annealed at 800 ºC has higher activity and stability. The reaction rate constant can reach 0.57 min -1 , and the activation energy was about 36.4 kJ/mol.

“…Furthermore, nitrogen distribution can be more uniform in carbon material by direction synthesis. Many substances can be used as precursors for NC materials by direct synthesis such as gelatin [9], chitosan [10], pyrrole [11], dopamine [12], and aniline [13].…”

Nitrogen-doped carbons (NCs) as supports for metal catalysts used in heterogeneous reactions are increasingly being investigated. In this work, NCs were prepared from monosodium glutamate (MSG) by direct carbonization, which were used as supporters to prepare Bi/NC catalysts. The Bi/NC catalysts were characterized by X-ray powder diffraction (XRD), X-ray photoelectron spectroscopy (XPS), transmission electron microscope (TEM), and nitrogen adsorption isotherm. The results indicate that nitrogen was doped in the formation of pyridinic N, pyrrolic N, and graphitic N. The NCs possess high surface area (~652 m 2 /g) and uniform mesopore size (~2.11 nm). Bismuth nanoparticles (NPs) dispersed uniformly in NC with diameter of 10-20 nm. The catalytic performances were investigated using the reduction of 4-nitrophenol (4-NP) with excess potassium borohydride as a model reaction, the results indicating that the Bi/NC catalysts have higher activity and better reusability than the Bi/AC catalyst. Under the following conditions: 100 mL of 4-NP (2 mM), 0.03 g of 3%Bi/NC, n(KBH4) : n(4-NP) = 40:1, and at room temperature, the rate constant k can reach 0.31 min -1 .

“…Molecular imprinting polymer and CMOS capacitive methods also need expensive reagents in beneficiation and derivatization before analysis, which makes them inconvenient in direct detection of aqueous samples. Comparatively, electrochemical method has many advantages, including simpleness, cost-effectivity, and high sensitivity [22]. Moreover, the electrochemical redox characteristic of DA permits very sensitive determination by modern electrochemical techniques at modified electrodes [23].…”

In this paper, dopamine (DA) ionic states in different pH solutions and corresponding electrochemical reaction characteristics on indium tin oxide (ITO) electrodes were discussed in detail. Polydopamine (PDA) and gold nanoparticles (AuNPs) have been used to modify ITO electrodes for selective sensing of DA in the present of ascorbic acid (AA). The impedance of PDA membranes and the catalysis of AuNPs on the interfacial properties of the modified electrodes were studied tentatively. Experiments show that a three-layer AuNP-PDA hybrid membrane-modified ITO electrode has an excellent property in DA detection without being interfered by the existence of AA. The sensitivity of DA detection was obtained to be 0.300 μA/μM with a detection limit of 0.06 μM (S/N = 3) in chronoamperometry measurement. The application of the electrode was verified in real sample analysis with both differential pulse voltammetry and chronoamperometry measurements.
