This study investigated the feasibility of the electrochemical degradation of benzene (C6H6) in a NaCl electrolyte solution between 0.05 and 0.5 M under the temperature of 298 K and reaction concentration between 1.28×10-5 and 1.28×10-3 M with an applied potential of 3 V was conducted in this study to investigate the destruction of the C6H6 in the batch reactors using a Pt/XC-72 composite as a catalyst. Experimental results indicated that the optimal conditions in the reaction were developed as a NaCl solution with 0.1 M at pH of 1.0 under C6H6 concentration of 6.41×10-4 M. The results reveal that electrochemical degradation of C6H6 in acidic medium is highly effective, while a maximum about 41% reduction at 120 min was achieved with Pt/XC-72 composite during the electrochemical degradation. In comparsion, the removal efficiency reached only 29% with the Pt electrode, showing the suitability of the Pt/XC-72 composites for electro-oxidation of C6H6. As a result, XC-72 carbon black materials played an important role in the decomposition of C6H6. Furthermore, the Pt/XC-72 composite used in this research has been developed as a potential catalyst for the application of C6H6 electro-oxidation.

Xps Study

In this paper we report the electrochemical behavior of heat-treated carbon blacks and Pt/C catalysts. Cyclic voltammetry indicates that the heat-treated carbon black as catalyst support does not improve the Pt/C catalyst's activity for methanol oxidation. An XPS study of a Pt-loaded carbon black indicates that the amounts of oxidized platinum and oxygen-functional groups on catalysts are decreased when the platinum particles are deposited on the heat-treated carbon surface. These changes in the surface and crystalline structural properties of carbon materials lead to the catalytic activity change in methanol electro-oxidation.

Superabsorbent Composite

AbstractIn this work, a novel water-managing superabsorbent composite was prepared by graft copolymerization reaction using acrylic acid (AA) and acrylamide (AM) as the monomers, calcium montmorillonite (Ca-MMT) as an inorganic component and sodium humate (SH) as fertilizer, and well characterized by means of Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM) and thermogravimetric analysis (TGA). The effects of the reaction temperature, neutralization degree of AA, amount of crosslinker, initiator, Ca-MMT and SH on water absorbencies were systematically investigated. The water absorbencies of the superabsorbent composite synthesized under optimal conditions with a Ca-MMT content of 20 wt% and an SH content of 30 wt% are 615 g g-1 and 45 g g-1 in distilled water and in 0.9 wt% NaCl solution, respectively. The swelling behaviours of the superabsorbent composite in various cationic salt solutions (NaCl, CaCl2 and FeCl3) were also investigated and it was found that at the same saline concentration (> 0.1 mmol L-1), the effect of three cationic salt solutions on the swelling capability has the following order: NaCl < CaCl2 < FeCl3. Here, it is worthy to point out that the water absorbency and swelling behaviours of the developed composite were improved by introducing simultaneously Ca-MMT and SH into PAA-AM network in comparison with that of incorporated single with Ca-MMT or SH.

Three kinds of ions (I-、Fe2+and MnO4-) were appended into the methanol aqueous solution respectively as an additive and the Cyclic voltammograms of the aqueous solutions were studied. The results showed that Fe2+had obvious promotion effect for electro-oxidation of methanol and could improve the methanol anodic oxidation current by 85 percent. The promotion effect of the thulium Ions were related with the electronic distribution of these elements and their adsorption on the Pt electrode surface. I-and MnO4-could facilitate the electro-oxidation of methanol at different extent.
