With increasing costs and instrument complexity, the university decided in the early 2000s to build a state-of-the-art shared research facility, The Center for Electron Microscopy and Nanofabrication (CEMN).
Novel CeMn a O x (a is the molar ratio of Mn to Ce) catalysts for catalytic decomposition of ozone (O 3) under high GHSV conditions were successfully synthesized by a facile homogeneous precipitation method.CeMn 10 O x showed ozone conversion of 96 % for 40 ppm O 3 under relative humidity (RH) of 65 % and space velocity of 840 L·g −1 ·h-1 after 6 h at room temperature, which is far ...
A redox co-precipitation method was employed to synthesize CeMn homogeneous solid solutions, utilizing various alcohols as activating agents. Ethanol effectively orchestrated the precipitation of CeO 2 and MnO x, promoting their co-growth.As a result, the CeMn-EA achieved 90 % toluene conversion at 218 ℃ (T 90 =218 ℃) with a weight hourly space velocity (WHSV) of 48000 ml/(g·h).
The Center for Electron Micrsocopy and Nanofabrication (CEMN) at Portland State Univesity (PSU) is a signature research facility of the Oregon Nanoscience and Microtechnology Institute (ONAMI), a collaboration between Oregon's research universities, Pacific Northwest National Laboratories and industry partners.
CEMN Director Jun Jiao has won a steady stream of large federal and industry grants and contracts, including some that focus on undergraduate training. Innovations in nanoscience and nanotechnology hold the promise of profound impacts in applications ranging from medical devices to green energy. Some of the best-established players responsible ...
The CeMn-0.4, characterized by a Ce/Mn molar ratio of 6:4, demonstrated exceptional catalytic activity and stability. The formation of CeMn solid solution strengthened the Ce-Mn interaction, y … Ce-based three-dimensional (3D) mesoporous microspheres with Mn homogeneous incorporation were synthesized.
The CeMn-2 and CeMn-3 catalysts exhibit higher specific reaction rate and TOF values among the four samples in the calculated temperature range (Fig. 1 b-d), revealing that the intrinsic activity of each active site for CeMn-2 and CeMn-3 is higher than that of the other catalysts.
The structural and magnetic properties of seven CeMn 2 Ge 2-x Si x compounds with x = 0.0-2.0 have been investigated in detail. Substitution of Ge with Si leads to a monotonic decrease of both a and c along with concomitant contraction of the unit cell volume and significant modifications of the magnetic states - a crossover from ferromagnetism at room temperature for Ge-rich compounds to ...
CeMn-0.4 exhibited the lowest apparent activation energy (E a), indicative of a lower energy barrier, thereby favoring the oxidation of toluene. Fig. 6 (d) presents the specific reaction rates (r norm) normalized by the BET surface area to mitigate the influence of surface area on reaction rate. CeMn-0.4 maintained the highest specific reaction ...
