Porous Ti with controlled pore structure was fabricated by thermal decomposition and sintering process using TiH 2 powders and Polymethylmethacrylates (PMMA) beads as pore forming agent. The beads sizes of 8 and 50 µm were used as a template for fabricating the porous Ti. The TiH 2 powder compacts with 20 and 70 vol% PMMA were prepared by uniaxial pressing and sintered for 2 h at 1100 • C. TGA analysis revealed that the PMMA and TiH 2 were thermally decomposed at about 400 • C forming pores and at about 600 • C into metallic Ti phase. The porosity increased with increase in the amount of PMMA addition. Also, the microstructure observation showed that the pore size and shape were strongly dependent on the PMMA shapes.

UTLENIANIE WYBRANYCH ROZCIEŃCZONYCH KOMPOZYTÓW SZKIEŁ METALICZNYCHPorous metallic materials have been widely used in many fields including aerospace, atomic energy, electro chemistry and environmental protection. Their unique structures make them very useful as lightweight structural materials, fluid filters, porous electrodes and catalyst supports. In this study, we fabricated Ni-based porous metallic glasses having uniformly dispersed micro meter pores by the sequential processes of ball-milling and chemical dissolution method. We investigated the application of our porous metal supported for Pt catalyst. The oxidation test was performed in an atmosphere of 1% CO and 3% O 2 . Microstructure observation was performed by using a scanning electron microscope. Oxidation properties and BET (Brunauer, Emmett, and Teller) were analyzed to understand porous structure developments. The results indicated that CO Oxidation reaction was dependent on the specific surface area.

“…Other porous metal structures, including cast 26 or electroplated metal grids or sintered particles, nanoparticles (NPs) or fibre meshes, have also been fabricated and commercialized and offer cheap and highly versatile pore structures that can be altered by changing the substrate geometry or the dimensions (size, length or aspect ratio), respectively [27][28][29][30] . The processing of either pure or alloyed porous metal structures has been demonstrated from noble metals, such as gold, palladium or platinum, as well as for copper, aluminium, nickel or iron, thereby offering a wide range of chemistries relevant to specific applications 31 . The recent interest in nano-textured metal surface chemistry has also opened new routes to the preparation of 'smart' functionalization of either metal oxide or pure metal surfaces 32 .…”

Porous metal frameworks offer potentially useful applications for the aerospace, automotive and bio-medical industries. They can be used as electrodes, actuators, or as selective membrane films. The versatility of the physical features (pore size, pore depth, overall porosity and pore surface coverage) as well as the large range of surface chemistries for both metal oxides and pure noble metals offers scope to functionalise metal nano-particles and networks of nano-porous metal structures. As well as traditional routes to producing metal structures, such as metal sintering or foaming, novel high-throughput techniques have recently been investigated. Nanoparticle self-assembly, metal ion reduction and deposition as well as metal alloy de-alloying were identified as sustainable routes to produce large surface areas of such nano-porous metal frameworks. The main limitations of the current fabrication techniques include the difficulty to process stable and homogeneous arrays of nano-scale pores and the control of their morphology due to the high reactivity of nano-structured metal structures. This paper aims at critically reviewing the various fabrication techniques and surface functionalization routes used to produce advanced functional porous metal frameworks. The limitations and advantages of the different fabrication techniques will be discussed in light of the final material properties and targeted applications.
