Porous carbon powders prepared by ultrasonic spray pyrolysis.
New, thermally robust meso- and macroporous carbon powders were prepared by ultrasonic spray pyrolysis (USP) of aqueous solutions using an inexpensive high-frequency ultrasound generator from a household humidifier. We choose our molecular precursors rationally, so that the expected decomposition pathways produce only remnant carbon atoms. Specifically, our rational design criterion led to halo...
متن کاملElectrical Properties of CZO Films Prepared by Ultrasonic Spray Pyrolysis
CuZnO (CZO) films have attracted increasing amounts of attention due to their promising potential applications in semiconductor devices. ZnO shows n-type conductivity, and attempts have been made to dope several elements in ZnO to improve the electrical properties. This study investigated the electrical property transitions of CZO films and determined the copper concentration at which the condu...
متن کاملNanocomposite mullite/mullite powders by spray pyrolysis
A mullite/mullite nanocomposite powder has been synthesized, composed of nanometer-size 3Al2O3 · 2SiO2 (‘3 : 2’) mullite precipitates within a matrix of the high alumina 2Al2O3 · SiO2 (‘2 : 1’) mullite. Historically, the transition from the metastable high-alumina phase to the thermodynamically stable ‘3 : 2’ phase of mullite has been thought to be a continuous process, involving a continuous s...
متن کاملPorous MoS2 synthesized by ultrasonic spray pyrolysis.
The hydrodesulfurization (HDS) activity of molybdenum sulfide-based catalysts is localized to the edges of this layered solid and is, therefore, highly dependent on the technique used to prepare the material. Here, ultrasonic spray pyrolysis (USP) was used to synthesize porous, nanostructured MoS2. Low surface area powders, not useful for catalysis, are generally produced by USP. This work show...
متن کاملPhotocatalytic Activities of Copper Doped Cadmium Sulfide Microspheres Prepared by a Facile Ultrasonic Spray-Pyrolysis Method.
Ultrasonic spray pyrolysis is a superior method for preparing and synthesizing spherical particles of metal oxide or sulfide semiconductors. Cadmium sulfide (CdS) photocatalysts with different sizes and doped-CdS with different dopants and doping levels have been synthesized to study their properties of photocatalytic hydrogen production from water. The CdS photocatalysts were characterized wit...
