Spherical core–shell alumina support particles for model platinum catalysts

Abstract: γ- and δ-alumina are popular catalyst support materials. Using a hydrothermal synthesis method starting from aluminum nitrate and urea in diluted solution spherical core-shell particles with uniform particle size of...

“…Sahin et al revealed the distribution of Cu nanoparticles on FDU-15 used for CO 2 reduction, and showed that nanoparticles found on the external surface of the FDU-15 were more affected by the Kirkendall effect during the oxidation (Sahin, 2018). Geerts et al used 3D electron tomography to reveal core-shell structure of alumina supports, confirming an average distribution of ultra-small Pt nanoparticles (Geerts et al, 2021). Mariusz et al studied how the 3D structures of Ptloaded TiO 2 nanotube arrays affected the formic acid electrooxidation activity (Andrzejczuk et al, 2019).…”

“…With the growing demand for high-performance and high-stability adsorbent materials, ceramic balls, as adsorbents for various gases and liquids, have achieved good results in environmental protection, such as sewage treatment, waste gas treatment, and air purification. However, in terms of high selectivity, ceramic balls also need to be modified to achieve better performance [27][28][29]. Therefore, it is of great significance to load polymer materials on ceramic balls.…”

“…[28] Spherical core-shell alumina was prepared by hydrothermal process using aluminum nitrate and urea solution. [29] Wan et al, synthesized γ-Al 2 O 3 microspheres with large pore volumes in a coaxial microchannel by temperature/pH-induced gelation method using Al(OH) 3 sol in the presence of methylcellulose and hexamethylenetetramine combining with microfluidics technology. [30] When morphologically tuned Al 2 O 3 is aimed to synthesize, it is necessary to include substantial quantities of capping agents and/or surfactants to achieve the desired product.…”
