High-yield synthesis of Ce modified Fe–Mn …

As can be observed, pure Fe–Mn alyst performed the lowest conversion with the ratio of chlorobenzene conversion at about 90% when temperature reached as high as 400 °C. Upon addition of Ce to the Fe–Mn alyst, the ratio of chlorobenzene conversion remarkably increased up to a Ce content of 5%, and Ce(5%)–Fe–Mn was the most active among all alysts achieving ∼99% chlorobenzene

A Review of Mesoporous TiO2 Thin Films | …

In our group 16,17, we prepared high-quality mesoporous titania thin films with good thermal stability (up to 600 °C) by using triblock copolymer Pluronic ® F127 as the structure-directing agent and tetrabutyl titanate as the inorganic precursor. The excellent thermal stability is correlated to the thick wall of the mesostrcture. The use of F127 as the templating agent was the premise for
