Solvent-Free Low-Temperature Annealing Method for Aqueous Stable Perovskite Nanofibers and Its Role in Peroxide Catalysis

One-dimensional nanofibers are among the most intriguing and desirable structures in nanomaterials. We report a solid-state green synthesis method for metal-oxide perovskite nanofibers (PNFs). A two-step low-temperature annealing method was optimized to obtain aqueous stable near-infrared-emitting Ce4.0Eu5.1Mo9.2Ox PNFs, with ∼100 nm of thickness and length up to several microns. The as-synthesized PNFs were employed to study the catalysis of...
