  以乙醇和水作为反应溶剂,聚乙烯吡咯烷酮(PVP)为表面活性剂,通过溶剂热法成功合成出了单分散类球形氧化铈纳米晶材料。通过改变反应参数,如反应时间,乙醇和水的体积比,PVP以及Ce(NO3)·6H2O溶液的浓度,实现了对氧化铈纳米晶粒度的有效调控。以类球形纳米晶CeO2作为载体,分别负载3wt%的金和钯,可以得到具有良好催化活性的Au-Pd/CeO2催化剂。

拓扑绝缘体和拓扑超导体是凝聚态物理最新的研究热点。拓扑晶化绝缘体(TCI)也是一种拓扑非平庸性的绝缘体,它的体态是绝缘体,而在高对称的晶体表面具有金属态。这种表面金属态受到镜面对称性的保护而不受无序或者非磁性杂质散射的影响。碲化锡经计算和角分辨光电子谱实验证实是一种拓扑晶化绝缘体材料。铟掺杂的碲化锡具有超导电性。
