“…The (Al VI )/(Al IV ) ratio is about 3.0 ( Table 2). As reported in the literature, a Al VI /Al IV ratio ranging from 2.4 to 3.8 is consistent with a mesoporous c-alumina structure [31][32][33]. The observation of an Al V signal is usually attributed to deviations from ideality of the cphase caused by the presence of Al sites with unsaturated coordination [31].…”

“…We prepared pure mesoporous aluminas using carboxylic acids with long chain hydrocarbons [11,[58][59][60]. Inexpensive mesoporous aluminas could be prepared using stearic acid salts such as magnesium or sodium stearate.…”

Mesoporous materials have attracted considerable attention for use as a catalyst or a catalyst support due to their remarkable textural properties such as high surface area and large pore volume with a narrow pore size distribution. Many efforts have been made to design mesoporous materials for use in heterogeneous catalyst systems. Recent progress and results regarding the preparation of nickel-mesoporous materials and their application to the hydrodechlorination of chlorinated organic compounds were discussed in this review. Mesoporous materials were used as a support for nickel catalyst or a nickel-incorporated mesoporous catalytic material in this work. Two research areas were described and discussed in this review. One is the preparation of mesoporous alumina-supported nickel catalysts and their application to the hydrodechlorination of 1,2-dichloropropane and o-dichlorobenzene. The other is the preparation of mesoporous silica-supported nickel catalysts and their application to the hydrodechlorination of 1,1,2-trichloroethane and chlorobenzene.

“…One common group of metal soaps is made from stearic acid, which is a saturated fatty acid that contains 18 carbons and is one of the most abundant fatty acids in the fats and oils of animals and plants. Many metal stearate salts are currently commercially available, typically including the alkali and alkaline earth metals . However, the stearate salts of platinum group metals, especially palladium, are rarely mentioned in the literature .…”

This report successfully demonstrates the synthesis and application of palladium stearates. It was found that the branching of the carboxylate anion of metal precursors could influence the size and shape of palladium nanoparticles (PdNPs). Worm-like nanowires were formed when using the branched isomer palladium isostearate (PdISt 2 ), while triangular nanoparticles were produced in a majority when using the normal form: palladium stearate (PdSt 2 ). Furthermore, when applying CO 2 to the system, both types of PdNPs transformed into more spherical shapes with smaller sizes. The formation of carbamates from the amine stabilizer with CO 2 could prevent the further growth and aggregation of PdNPs. The PdNPs were tested as catalysts for the hydrogenation of styrene, and higher catalytic activities were achieved with PdNPs that were prepared with the assistance of CO 2 .
