Abstract A crystalline mesoporous cobalt phosphate (meso-CoPi) electrocatalyst is prepared using liquid crystal template of non-ionic surfactant of Brij®78. The physicochemical investigations of the electrocatalyst executed by surface area analyzer, XRD, transmission electron microscope submits creation of a mesoporous crystalline nanostructured of meso-CoPi with a surface area of 124 m2 g−1. This is an 10-fold greatness superior than that for bulk-CoPi particles produced without surfactant template. The meso-CoPi electrocatalyst comprises of metallic cobalt layered with a cobalt-oxo/hydroxo-phosphate layer which facilitates the electro-oxidation of methanol at modest overpotential of

碱性溶液中甲醇氧化反应用液晶模板制备介孔磷酸钴电催化剂

摘要 以Brij®78 非离子表面活性剂为液晶模板，制备了结晶介孔磷酸钴（meso-CoPi）电催化剂。由表面积分析仪、XRD、透射电子显微镜对电催化剂进行的物理化学研究表明，可以产生表面积为 124 m2 g-1 的介孔 CoPi 介孔晶体纳米结构。这比不使用表面活性剂模板生产的块状 CoPi 颗粒高 10 倍。meso-CoPi 电催化剂由金属钴和钴-氧/羟基-磷酸盐层组成，该层有利于甲醇在适度的过电位下电氧化
