“…Immersing the membranes in a hydrothermal solution without sealing both ends may be attributed to this uniform deposition. This approach was rather similar to the incipient wetness impregnation [19]. The dilute hydrothermal solution has the ability to penetrate into the constricted membranes' pores (sponge-like and finger-like pores) without the necessity to use pressure to enable the Fe 2 O 3 distribution to be carried out effectively.…”

Removal by absorptive ceramic membranes can simultaneously absorb and separate metal ions from water. Alumina/yttria-stabilized zirconia (Al 2 O 3 /YSZ) hollow-fiber membranes, fabricated using phase inversion and sintering process, were deposited with iron oxide by an in-situ hydrothermal process. The results showed that a-Fe 2 O 3 was produced and incorporated across the membranes. A reduction in flux was recorded with the deposition of a-Fe 2 O 3. However, it improved the adsorption capacity for heavy metal adsorption. The adsorption-separation test demonstrated that the optimized membrane is able to completely remove Pb(II) ions after two hours.

“…Furthermore, the PNP reduction can be carried out in a flow through mode, which can dramatically strengthen the mass transfer and completely reduce PNP to PAP [13,18]. Our group has developed sheet and tubular ceramic catalytic membranes for stable and efficient PNP reduction in flow through membrane reactors [13,18,19]. Moreover, the surface modification of the ceramic membranes with functional groups and oxides can significantly improve the Pd content and the interaction between the Pd nanoparticles and ceramic membranes, and then enhance the catalytic activity and stability of the catalytic membranes [13,19,20].…”

Flexible and hierarchical nanostructured Pd/SiO 2 -TiO 2 nanofibrous catalytic membranes were fabricated via combining electrospinning technique and a two-step hydrothermal method. The size and distribution of TiO 2 nanorods immobilised on SiO 2 nanofibrous membranes can be regulated via adjusting the dosage of TiCl 3 solution in the first step hydrothermal process. When using an optimal TiCl 3 solution dosage of 0.2 mL, a hierarchical structured Pd/SiO 2 -TiO 2 -0.2 nanofibrous catalytic membrane with uniformly dense TiO 2 nanorods loaded on SiO 2 nanofibers is obtained, and still shows good tensile strength and flexibility. The catalytic activity of Pd/SiO 2 -TiO 2 -0.2 increases 5 times as compared to Pd/SiO 2 -TiO 2 -0 in the reduction of p-nitrophenol (PNP) to p-aminophenol (PAP). The modification with TiO 2 nanorods can provide more surface areas for loading the Pd nanoparticles, thereby increased active sites. The three-dimensional open-cell network stacked and assembled by thousands of SiO 2 nanofibers and TiO 2 nanorods enhances the contact between the reactants and Pd nanoparticles. Both aspects contribute the superior catalytic activity of Pd/SiO 2 -TiO 2 -0.2. Furthermore, a continuous and complete conversion of PNP to PAP can be stably operated over 240 min in a gravity-driven catalytic membrane reactor constructed by Pd/SiO 2 -TiO 2 -0.2.

“…[33] Different methods can be used for the deposition of metallic NPs on ceramic supports. [34][35][36][37] For instance, the formation of covalent bonds on the surface of the silica via silanization and subsequent metalation requires several steps of synthesis. [12] Another alternative is the deposition of metal NPs using water/oil microemulsions.…”

Integrating Reactors and Catalysts through Three‐Dimensional Printing: Efficiency and Reusability of an Impregnated Palladium on Silica Monolith in Sonogashira and Suzuki Reactions

et al. 2020

For this work, an integrated system composed of a polypropylene reactor and a palladium on silica monolithic catalyst was designed and manufactured by 3D‐printing. These devices are able to perform solution phase chemistry in a robotic orbital shaker. The capped reactor was obtained in its entirety by 3D‐printing, using polypropylene and fused deposition modeling. The monolithic catalyst was also obtained by 3D‐printing ‐robocasting‐ of a silica support, sintering and subsequent palladium deposition through the wet impregnation method. The catalytic efficiency in Sonogashira or Suzuki reactions as well as the recyclability of the entire system – catalyst+reactor – were studied. The strong electrostatic adsorption (SEA) of the palladium on sintered silica and the reduced mechanical stress produced by the convenient adjustment of the catalyst into the polypropylene reactor makes the catalytic system reusable without significant loss of catalytic activity.
