中文摘要:采用高温水热法制备稳定、高度晶化的介孔氧化铝材料(M-Al2O3-n),通过异丙醇铝前驱体与聚四乙烯基吡啶(P4VP)模板间的酸碱自组装实现材料介孔结构的构筑,再经高温水热处理(180℃)实现孔壁的晶化,并通过担载少量的铂活性组分研究其在催化完全燃烧苯中的性能.结果表明:M-Al2O3-n具有高度晶化的孔壁结构和典型的γ-Al2O3晶型;M-Al2O3-n具有较大的比表面积(335m2/g)、孔容(1.36cm3/g)和均一的孔径分布(16.1nm);M-Al2O3-n具有粗糙的表面结构及丰富的纳米多孔结构;该材料负载少量的铂(质量分数为0.3%)活性组分得到的新型催化材料在较温和的条件下即可将苯类VOCs完全催化燃烧.
外文摘要:Stable crystalline mesoporous Al2O3(M-Al2O3-n)supporting Pt with good catalytic activity for benzene combustion have been successfully prepared.M-Al2O3-ns support was synthesized from the self assembly of Al precursor with poly 4-vinylpyridine(P4VP)template based on their strong acid-base interactions,followed by hydrothermal treatment at 180℃and calcination at 550℃.XRD patterns show that M-Al2O3-ns are highly crystalline withγ-Al2O3character.N2isotherms and pore size distribution show that M-Al2O3-ns have a high BET surface area(335m2/g),large pore volume(1.36cm3/g)and uniform mesopores(16.1nm).SEM images show that M-Al2O3-ns have rough surface and abundant mesopores.Catalytic tests show that M-Al2O3-ns exhibit excellent activity for benzene combustion under rather mild conditions.
