Solvothermal synthesis carboxylates

Carboxylic acids can be used as the media for the solvothermal synthesis of inorganic materials. Synthesis of magnetite by thermal decomposition of an iron... 

Another way to induce visible-light photocatalytic activity is the chemical bonding of carboxyl groups onto the SrTiOs surface during the microwave-assisted solvothermal synthesis in KOH methanol-oleic acid solutions [30]. This behavior was assigned to a dipole layer that induced an attracting potential for electrons inside the SrTiOs nanoparticles. The photocatalysts were tested in the photooxidative decomposition of NO [31].

A final TCPP MOF of interest is found in a report that described the synthesis of M + (TCPP) (M +=Cu +, Ni +, and Pd + ) MOFs with dirhodium(II) carboxylate paddlewheel SBUs (110). The compounds were prepared via solvothermal reaction of rhodium acetate and M (TCPP) in methanol. The materials were poly cry stalline, and so structural information was deduced from powder X-ray deffraction (PXRD), elemental analysis, infrared (IR) spectroscopy, and other... 

The nonhydrolytic M—O—M bond formation via ester elimination between metal alkoxides and carboxylic acids is a well-known approach in sol-gel chemistry. In this direction, titanium -butoxide and acetic acid were used for the nonhydrolytic synthesis of anatase Ti02 nanopartides at 100 °C [92]. Moreover, spindle-shaped nanoporous anatase Ti02 mesocrystals with a single-crystal-like structure and tunable sizes were synthesized in the tetrabutyl titanate and acetic acid system without any additives imder solvothermal conditions [93]. A complex mesoscale assembly process, involving oriented aggregation of tiny anatase nanocrystals and entrapment of in situ produced butyl acetate as a porogen, was proposed for the formation of the mesocrystals. They exhibited a good performance as anode material for lithium ion batteries [93].
