近年来，伴随着太阳能等清洁能源的迅猛发展，太阳能光电方面的研究和应用等迅速发展，特别是多晶硅产业。每生产一吨的多晶硅，会产生300 -500 kg的硅微粉。若这些硅微粉不能及时妥善处理，不仅会造成严重的固体废物污染，而且也会造成资源的浪费。
石河子大学化学化工学院工业催化课题组以多晶硅产业的硅微粉（SF-SiO2）作为前驱体，成功制备了多孔SiC纳米陶瓷材料（SF-SiC），并将其作为载体，制备出了具有富含缺陷的Ni/SF-SiC催化剂。Ni缺陷对H2和CO具有较强的吸附能力，可有效增强CO甲烷化反应的活性。同时，SiC优异的导热性可以降低催化剂床层中热点的影响，使Ni/SF-SiC具有优良的抗烧结和抗积碳性能。相比与Ni/SF-SiO2催化剂（89.8%），Ni/SF-SiC催化剂在350 oC时的CO转化率可达99.1%，反应50 h后几乎无衰减。相关工作以Defect-rich nickel nanoparticles supported on SiC derived from silica fume with enhanced catalytic performance for CO methanation为题，在Catalysts上发表（图1），第一作者为化学化工学院硕士研究生宋奇，通讯作者于锋副教授、葛贵贤副教授和张金利教授。
