    摘要:

    以陽(yáng)極氧化鋁(AAO)膜為模板,采用真空機(jī)械壓注法制備銦錫(InSn)合金納米線(NWs),然后采用“原位放電還原”方法在InSn NWs表面包覆Ru顆粒。隨后,將復(fù)合材料在空氣中進(jìn)行熱處理,合成RuO2/ITO NWs。最后,在H2氣氛下還原RuO2/ITO NWs獲得Ru/ITO NWs。結(jié)果表明,InSn納米線直徑約為40 nm,2 ~ 5 nm的Ru納米顆粒均勻地包覆在ITO NWs的表面。此外,檢測(cè)了所得Ru/ITO NWs對(duì)纖維素的催化熱解性能,所得產(chǎn)物為1,6-脫水吡喃葡萄糖、乙醇醛和羥基丙酮,對(duì)比無(wú)催化劑、ITO NWs,Ru/ITO NWs所得產(chǎn)物,可以發(fā)現(xiàn)Ru/ITO NWs催化劑減少了1,6-脫水吡喃葡萄糖的產(chǎn)生,表明Ru納米顆粒加劇了熱解過(guò)程中的氧橋的斷裂,加速生成乙醇醛和羥基丙酮,提高纖維素?zé)峤庑?。同時(shí)對(duì)存在醚鍵的壬基酚聚氧乙烯醚也進(jìn)行了熱解分析,結(jié)果表明Ru/ITO NWs對(duì)醚鍵的斷裂起明顯的催化作用。

    Abstract:

    Indium tin (InSn) alloy nanowires were prepared using anodic aluminum oxide (AAO) film as template through vacuum mechanical injection method. Ru particles were then coated on the surface of InSn nanowires using the "in situ discharge reduction" method. Subsequently, the tin oxide nanowires (ITO NWs) was obtained by heat treatment of the composite material. Finally, RuO2/ITO NWs were reduced in H2 atmosphere to obtain Ru/ITO NWs. The results indicate that the diameter of InSn nanowire is about 40 nm and Ru nanoparticles of 2-5 nm are uniformly coated on the surface of ITO NWs. In addition, the catalytic pyrolysis of cellulose by Ru/ITO NWs was tested and the main products were 1,6-anhydropyranose, glycoladehyde, and hydroxyacetone. Compared the catalysate of ITO NWs without catalysts, Ru/ITO NWs catalyst reduces the production of 1,6-anhydropyranose, indicates that Ru nanoparticles exacerbate the fracture of oxygen bridges during pyrolysis, accelerate the generation of glycoladehyde and hydroxyacetone, and improve the pyrolysis efficiency. At the same time, the pyrolysis of nonylphenol polyoxyethylene ether with ether bonds is also carried out, and the result shows that Ru/ITO NWs plays a role in the fracture of ether bonds.
