“…However, if the stable metal content is too low, that is, less than 5 at%, the nanoporous structure may not form. Therefore, a stable metal content of 8-15 at% is recommended [4][5][6][7][8][9][10][11][12][13][14]. In addition, it is important to consider whether the components can form alloys.…”

Nanoporous oxides, such as cupric oxide (CuO), nickelous oxide (NiO), titanium dioxide (TiO 2), cobaltosic oxide (Co 3 O 4), and cerium oxide (CeO 2), and noble-metal-based nanoporous composites, such as silver (Ag) ligaments loaded with CeO 2 , TiO 2 , zirconium dioxide (ZrO 2) or NiO and palladium (Pd) ligaments loaded with TiO 2 or ZrO 2 , are described in the chapter. Oxide-based nanoporous composites, such as Au loaded on CuO and CeO 2 or platinum (Pt) loaded on TiO 2 , are also summarized. The structures, microstructures, and microstructure parameters of these materials are reviewed. The performance of the noble-based nanoporous composites is presented, including the catalytic oxidation of methanol and ethanol. Environmental protection applications, such as catalytic oxidation of carbon monoxide (CO) for the oxide-based nanoporous composites, have also been developed. Applications of rare earth elements in nanoporous materials are also reviewed.

“…With this synergistic effect, FAO activity was increased by 67 times compared to that of Pt NPs supported directly on a glassy electrode. Ni‐based supports have also attracted abundant research interest: the precious metals in combination with Ni‐based supports reported recently involve Au, Pt, Pd and bimetallic Pt−Rh. Nevertheless, their applications in anode reactions differ from each other, primarily depending on the category of precious metals as well as the level of synergy.…”

“…On the other hand, Pt and Pt−Rh catalysts deposited on Ni supports were used for ethanol oxidation, accelerated by Pt‐surface‐generated oxidative species . Pd/NiO catalytic system was employed for methanol oxidation . The unique fabrication process by dealloying of a melt‐spun Al−Pd−Ni precursor, results in porous morphology of the derivative.…”

Polymer electrolyte fuel cells (PEFCs) are among the most advanced energy technologies with low operating temperatures, high energy densities, ease of transportation and storage. However, the deficiencies such as low activity and high cost of the electrocatalysts at anodes greatly hinder their commercialization. The commonly used carbon black supports lack the capacity of regulation over the supported noble metals towards efficient electro‐catalytic oxidation of fuels. In this Mini‐Review, the prerequisite factors in advanced supports are outlined, ranging from self‐supported precious metal alloys as well as non‐noble metal materials, while simultaneously revealing the superiorities of some advanced supports beyond carbon black in terms of electronic conductivity, synergy with surface precious metals, chemical and electrochemical stability, and other possible interactions. The effects arisen from microscopic morphology, nano‐structure, and composition on the electrocatalytic activity/stability are also discussed. Finally, several of the most promising supports are highlighted, and the research trends of synergistic supports in future PEFCs are predicted.

Fe3O4/FeO/CoNikompozit malzemesi iki aşamalı proses kullanılarak üretilmiştir. Birinci aşamada, oksit prekürsörü (öncül malzeme) ıslak sentez esaslı Pechini yöntemi kullanılarak düşük sıcaklıkta üretilmiştir. İkinci aşamada prekürsör malzemesi 500, 600, 700 veya 800 °C'ye hidrojen gazı altında ısıtılarak indirgenmiştir ve metal/oksit kompozit malzemesi elde edilmiştir. Farklı sıcaklıklarda üretilen malzemelerin yapısal, morfolojik ve manyetik özellikleri X-ışını kırınımı, tarama elektron mikroskobu ve titreşen örnek manyetometresi kullanılarak incelenmiştir. 600 °C'den 700 °C'ye geçişte manyetik özelliklerde ani değişiklikler gözlenmiştir. Doygunluk mıknatıslanması iki katına çıkarken, koersif kuvvet yarıya inmiştir. Bu değişiklikler manyetik CoNi fazın amorf bir yapıdan kristal bir yapıya geçişiyle ve Fe3O4 fazın parçacık boyutunun yaklaşık olarak iki katına artmasıyla açıklanmıştır. Fe3O4/FeO/CoNi composite materials were produced using a two-step process. In the first step, oxide precursor was produced at low temperature by wet-synthesis based Pechini method. In the second step, the precursor was heated to 500, 600, 700 or 800 °C under reducing hydrogen gas and metal/oxide composite material was obtained. The structural, morphological and magnetic properties of materials produced at different temperatures were investigated using X-ray diffraction, scanning electron microscope and vibrating sample magnetometer. Sudden changes in magnetic properties were observed during transition from 600 °C to 700 °C. The saturation magnetization doubled while coercive force was halved. These changes were explained with the crystallization of magnetic CoNi phase from an amorphous state and nearly doubling of particle size of Fe3O4 phase.
