摘要:The present invention relates to formation of nanocubes of sillenite type compounds, such as bismuth titanate, i.e., Bi 12 TiO 20 , nanocubes, via a hydrothermal synthesis process, with the resulting compound(s) having multifunctional properties such as being useful in solar energy conversion, environmental remediation, and/or energy storage, for example. In one embodiment, a hydrothermal method is disclosed that transforms nanoparticles of TiO 2 to bismuth titanate, i.e., Bi 12 TiO 20 , nanocubes, optionally loaded with palladium nanoparticles. The method includes reacting titanium dioxide nanotubes with a bismuth salt in an acidic bath at a temperature sufficient and for a time sufficient to form bismuth titanate crystals, which are subsequently annealed to form bismuth titanate nanocubes. After annealing, the bismuth titanate nanocubes may be optionally loaded with nano-sized metal particles, e.g., nanosized palladium particles.

摘要:A template-free reverse micelle (RM) based method is used to synthesize pyrochlore nanostructures having photocatalytic activity. In one embodiment, the method includes separately mixing together a first acid stabilized aqueous solution including pyrochlore precursor A and a second acid stabilized aqueous solution including pyrochlore precursor B with an organic solution including a surfactant to form an oil-in-water emulsion. Next, equimolar solutions of the first and second acid stabilized oil-in-water emulsions are mixed together. Then, the mixture of the first and second acid stabilized oil-in-water emulsion is treated with a base to produce a precipitate including pyrochlore precursors A and B. After which, the precipitate is dried to remove volatiles. The precipitate is then calcined in the presence of oxygen to form a pyrochlore nanostructure, such as a bismuth titanate (Bi 2 Ti 2 O 7 ) pyrochlore nanorod. The method of synthesizing the pyrochlore nanorod is template-free.

摘要:Carbon fluoride is synthesized by reactively or high intensity/energy milling at ambient room temperature carbon-containing material (such as graphite, carbon black, coke, or other carbon-based material) with an inorganic fluoride agent (such as cobalt trifluoride) other than fluorine gas. The following chemical reaction occurs: xC+CoF 3 →C x F+CoF 2 , wherein x equals 1 to 4. The C x F is separated from the CoF 2 and the CoF 3 by digesting the C x F, CoF 2 and the CoF 3 in hot water of at least approximately 90° C. causing the CoF 2 to dissolve; and then filtering the CoF 2 . The CoF 3 is unreacted and undergoes hydrolysis in the hot water to form Co(OH) 3 or Co 2 O 3 .3H 2 O, which is removed by washing with sulfuric acid. Alternatively, the C x F is separated from the CoF 2 and the CoF 3 by digesting the C x F, CoF 2 and the CoF 3 in heated sulfuric acid followed by filtration and washing with sulfuric acid and then with hot water. The synthesized carbon fluoride is used to form a cathode in electrochemical cells, such as lithium batteries.
