褐煤的热解反应是褐煤利用的重要研究方向之一。为了分析褐煤热解过程中结构演变及气体生成机理,首先将胜利褐煤(SL)在固定床上进行热解制焦,利用800℃时SL热解气体生成速率曲线选取半焦终温,同时用气相色谱在线检测其所生成的热解气;其次结合煤焦傅里叶变换红外光谱(FT-IR)的表征进行分析,将半焦的FT-IR分峰拟合计算;最后将计算参数结合热解气生成规律,提出了热解升温过程中各反应阶段生成气体机理和气体生成过程中煤体结构的演变规律。结果表明,SL具有羟基、脂肪烃、芳环、羰基、醚键等丰富的官能团,热解温度低于350℃,胜利褐煤中主要官能团未发生明显变化; 350～450℃,脂肪族侧链含氧官能团分解,热解温度450℃比350℃时煤焦中C=O相对含量(C1)降低78%; 560～800℃,热解反应主要以芳香烷基侧链含氧官能团裂解为主,热解温度800℃时煤焦中C—O相对含量(C2)比560℃时降低27%;热解温度710～800℃时,煤热解以缩聚反应为主,热解温度800℃煤焦中芳香稠和度(D2)比710℃时升高65%。对4种热解气生成过程进行研究分析,CO2主要来源于中低温区煤中不同结构的羧基官能团分解;高温区生成CO,来源于煤中酚类、醚类、含氧杂环等结构的分解; CH4主要由芳环侧链的甲基、亚甲基或连接芳环结构亚甲基的分解;高温区产生的约60%H2主要来自于煤中芳香结构的缩聚反应。

Chinese Science Bulletin 2005年第17期50卷 1846-1848页

作者： zhao Dan WU Gang XU boqing Innnvative Catalysis Program Key Lab of Organic Optoelectronics & Molecular Engineering Department of Chemistry Tsinghua University Beijing 100084 China

Aucore-Ptshell (Au@Pt) nanoparticles were syn-thesized at room temperature by reducing K2PtCl6 with hy-drogen in the solution containing Au colloids and polyvi-nylpyrrolidone (PVP). The particles obtained were charac-terized with UV-Vis, TEM and XPS techniques. UV-Vis spectra show that the surface plasmon absorption feature of Au colloids is significantly reduced with increasing the amount of reduced Pt. TEM images that the metals are found always appear as spherical nanoparticles and their sizes grow apparently due to the reduction of PtCl62? ions, indicating that Pt is deposited from solution onto Au particle surface and forms a Pt-layer with uniform thickness. In the XPS spectra, the signals of Au metal decrease due to the re-ductive deposition of Pt on the surface of the Au colloids. UV-Vis and XPS data are consistent in showing that when the amount of Pt in the AuPt colloids is increased to reach an overall atomic ratio of Pt/Au = 2, the Pt deposits form a shell covering completely the surface of Au particles, demonstrat-ing the core-shell structure of the synthesized AuPt particles.

采用循环伏安扫描测试对不同浓度的甲酸在纳米Au颗粒（（10.0±1.2）nm）承载Pt电催化剂（记为Ptm^Au,其中m为Pt/Au原子比）上的电化学氧化过程进行了研究.结果表明,Pt在纳米Au颗粒表面的形态对甲酸的电化学氧化行为影响显著.当Pt对Au颗粒形成壳层覆盖（m〉0.2）时,甲酸电氧化反应主要发生在高电势（相对SCE电极为0.6~1.0 V）范围,与常规Pt/C电催化剂上甲酸的电氧化行为类似;当Au表面Pt的形态由单原子壳层（m=0.2）递变为不大于1.0 nm的Pt原子簇或原子筏（m〈0.2）时,在低电势（-0.2~0.6 V）范围也能明显检测到甲酸的电氧化反应,而且随着m的减小,Pt的质量比活性显著提高.Pt呈现100%暴露（电化学活性面积EAS=236 m2/g-Pt）的Pt0.05^Au/C电催化剂在甲酸电氧化峰（0.38 V）处的质量比活性是通常Pt/C电催化剂（Pt分散度为30%或EAS为74 m2/g-Pt）的40倍,表明随着Au颗粒上Pt尺寸的减小或分散度的提高,Ptm^Au/C电催化剂对甲酸电氧化反应的催化活性也显著提高.在甲酸浓度由0.2 mol/L渐提高至3.2 mol/L时,Ptm^Au/C和Pt/C催化剂上甲酸电氧化反应的比电流均呈先增大后减小的火山形变化,表明适宜的甲酸工作浓度也是在Pt基催化剂上实现高功率直接甲酸燃料电池的关键因素之一.

以多壁碳纳米管(MWCNTs)为载体,制备了Pt载量为20%的Pt-(RuOxHy)m/MWCNTs催化剂(m为Ru/Pt原子比),在m≤0.4时考察了不同电势区间循环伏安预处理对其催化性能的影响.水合氧化钌(RuOxHy)的存在明显提高了Pt催化剂抗CO毒化的能力,而在甲醇电氧化反应中Pt的质量比活性(MSA)随样品中m值增大呈先升后降趋势.经低电势区间(-0.20-0.46 V vs SCE)预处理稳定的催化剂中,Pt-(RuOxHy)0.10/MWCNTs样品中Pt的甲醇电氧化反应的MSA提高至相应单组分Pt/MWCNTs的9倍.将预处理电势区间扩展到高电势(即-0.20-0.96 v vs SCE)会造成钌组分溶解流失,导致催化剂抗CO毒化能力下降.在经过高电势区间的预处理后,Pt-(RuOxHy)020/MWCNTs对甲醇电氧化反应呈现出最高的催化活性,为单组分Pt催化剂的1.4倍.这些结果证实,水合氧化钉是Pt电催化剂的有效助剂.
