Deposition parameters and Raman crystal orientation measurements of ceria thin films deposited by spray pyrolysis

Abstract

Ceria thin films deposited by spray pyrolysis show a strong preferential 〈200〉 orientation after annealing corresponding to the {100} facet of high catalytic activity. This texture correlates with an unusually strong blue shift of the Raman F2g peak.

Reversible perovskite-fluorite phase transition in alumina-supported CeFeOx films

“…13,35 After calcination in air at 1073 K, however, the bulk sample separated into two phases, which can be identified as CeO 2 and α-Fe 2 O 3 . 36–38 This result is distinct from that of the thin-film sample, where α-Fe 2 O 3 peaks were not observed for the oxidized sample.…”

Ir/IrOx/WO3 electrocatalysts for water splitting

“…The absence of tungsten oxide diffraction peaks could be attributed to the WO 3 nanoparticles with a small size and poor crystallization. 21 As revealed from transmission electron microscopy (TEM) images, the as-synthesized catalysts with a theoretical Ir/W molar ratio of 8 : 2 that were calcinated at 350 1C displayed a wire-like shape with a diameter in the range of 20-40 nm (inset of Fig. 1b).…”

A Novel Instantaneous Self-Assembled Hollow MOF-Derived Nanodrug for Microwave Thermo-Chemotherapy in Triple-Negative Breast Cancer

“…Spray pyrolysis or the aerosol flow strategy is a kind of twophase interface method, mainly using spray tools to transform the precursor solution from liquid to nano-/micron fog droplets or aerosols and then transporting them to the heating region with the help of flowing carrier gas. 31 At high temperatures, the solvent in the fog droplets rapidly volatilizes to generate reactants. Compared with other synthesis methods, spray pyrolysis, in which chemical reactions are carried out in independent small units without interference, has higher synthesis efficiency and faster reaction speed.…”
