Synthesis of nanoporous bismuth films by liquid-phase deposition

“…68,69 Although the gaseous products will burn, the solid intermediates may remain at the liquid surface, accumulating and possibly forming a viscous shell. The evolving shell inhibits further vaporization, and might trap and superheat the high-volatile xylene, thus facilitating droplet disruptions.…”

Disruptive burning of precursor/solvent droplets in flame‐spray synthesis of nanoparticles

Flame spray pyrolysis is an established technique for synthesizing nanoparticles in the gas phase through aerosol combustion of precursor/solvent droplets. The combustion characteristics of isolated micron-sized precursor/solvent droplets are investigated experimentally. Pure solvent droplets burn uniformly and classically quasisteady, whereas precursor/ solvent droplets manifest disruptive combustion behavior. The fast onset of droplet disruption, which occurs only for solutions with dissolved metal precursors, is not due to solid-particle precipitation within the droplet. Instead, the mechanism of disruptive droplet burning is similar to that of slurry droplets, consisting of three main steps: (1) diffusioncontrolled burning of the high-volatile solvent, (2) viscous-shell formation due to decomposition of the low-volatile metal precursor, and (3) subsequent disruption due to heterogeneous nucleation. The time sequence of the three steps depends on the concentration and decomposition characteristics of the metal precursor, shortening with increased concentration and higher incremental decomposition temperature.

“…Thermal and mesomorphic properties are the most important properties of metal alkanoates, which have played an important role in the evaluation of a significant interest on the study of liquid-crystalline properties of coordination compounds. TGA studies of metal 2-ethylhexanoates show either a two- 58 or a three-stages 57 decomposition process. For Bi(III) 2-ethylhexanoate, experiments in flowing N 2 show that 2-ethylhexanoate ligand itself serves as the oxygen source in forming the bismuth oxide.…”

Metal 2-ethylhexanoates and related compounds as useful precursors in materials science

This critical review deals with the chemistry and applications of metal alkanoates with medium size (C5 to C12) carbon chain length. A particular emphasis is given to metal 2-ethylhexanoates, which find wide applications as metal-organic precursors in materials science, as catalysts for ring opening polymerizations and also in painting industries for their properties as driers. After a brief introduction and an overview of synthesis, structural and physico-chemical properties, this article discuses extensively the applications of these compounds in materials science. Finally, it identifies and signifies the areas for future research in the looking ahead section. The aim of this review is to bridge the areas of precursor's chemistry and materials science by providing a reference text for researchers working either in or at the interface of these two areas (125 references).
