英文摘要	以SiO2和Li2CO3为反应原料,采用高温固相法于不同温度下合成了一系列可在高温500￣750℃之间直接吸收CO2的硅酸锂(Li4SiO4)材料。采用扫描电子显微镜(SEM)、X射线粉末衍射仪(XRD)分别观察和评价了合成材料的表面形貌与结构特征,用热重分析仪(TG)研究了硅酸锂材料吸收CO2的性能。实验结果表明,在750℃下煅烧6h即可合成出吸收CO2性能良好的硅酸锂材料,在CO2气氛下,于700℃保持约15min即可达到吸收平衡,其吸收量约达43%(wt)左右。与文献报道相比,材料的合成条件有所改善,材料吸收CO2的容量也有较大提高。; Li4SiO4 used as a CO2 absorbent at 500 degrees C to 750 degrees C was synthesized by SiO2 and Li2CO3 The crystal structure and microstructure of Li4SiO4 materials were characterized by XRD and SEM, respectively, and the CO,absorption ability of the Li4SiO4 materials was studied by TG. The results showed that Li4SiO4 with good ability of CO2 absorption could be prepared at 750 T for 6 h. The absorbing balance in CO2 atmosphere could be arrived during 15 min at 700 degrees C, and the absorption amount was about 43%(wt). The synthesis conditions were optimized and the absorption capacity was improved as compared to literature methods.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000235054700015&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 5; 02; 268-272; 22
