Functionalization of carbon support and its influence on the electrocatalytic behaviour of Pt/C in H2 and CO electrooxidation

Chemical modification of Carbon Vulcan XC-72R for fuel cell applications has been undertaken. Treated carbons were used as carriers for the deposition of Pt nanoparticles and used as electrocatalysts. The influence of the carbon treatment, as well as that of the Pt nanoparticles generation and their deposition route has been studied. The behaviour of the electrocatalysts in the CO and hydrogen oxidation reaction (HOR) has been studied. It was observed that carbon pre-treatment lead to difference behaviour in the CO oxidation reaction compared with the performance over non treated supports. In this way, CO oxidation was controlled by the nature of the support rather than by the nature of the Pt particles alone.

Effect of filler network on dynamic viscoelastic properties of uncured polymethylvinylsiloxanes filled with silica and carbon black

Dynamic properties of polymethylvinylsiloxane (PMVS) filled with filler‐blends composed of carbon black (CB) and silica (SiO₂) were investigated using an advanced rheometric expansion system. A variety of weight fraction of CB to SiO₂ were 0/100, 10/90, 30/70, 50/50, 70/30, 90/10, and 100/0, and a bifunctional organsilane, bis(3‐triethoxysilylpropyl)tetrasurfane, was used to facilitate the filler dispersion. The results reveal that the incorporation of CB/SiO₂ filler‐blends into PMVS result in a reduced Payne effect. This effect reaches a minimum when the ratio of CB/SiO₂ approaches 1, and then it began to rebound with the ratio increase. Meanwhile, a characteristic Newtonian viscosity plateau appearing in low frequencies also significantly decreases, depending on the amount of CB or SiO₂ added. On the basis of a simplified Fowke model, we ascribe this phenomenon to the deteriorated filler network, which is predominantly induced by the totally different surface activity between CB and SiO₂. © 2006 Wiley Periodicals, Inc.

炭黑品种及用量对NBR/CHR并用胶性能的影响

研究了炭黑Ｎ６６０、Ｎ６３０、Ｎ７６２、天然气半补强炭黑及喷雾炭黑对ＮＢＲ／均聚氯醚橡胶（ＣＨＲ）并用胶性能的影响。试验结果表明，这些炭黑在ＮＢＲ／ＣＨＲ并用胶中的用量达到８０份时，并用胶的加工性能仍较好。随着炭黑用量的增大，ＮＢＲ／ＣＨＲ并用胶的耐四氯化碳性能提高；压缩永久变形、压缩温升及硬度增大；扯断伸长率和回弹值下降；而拉伸强度则是先升高，当炭黑用量达到６０份时即下降；撕裂强度也是先升高，而后在不同用量处出现下降趋势。
