“…Induction heating systems consist of an inductor and a power source with a link of increased frequency [29][30][31]. By varying the frequency of commutations, it is possible to regulate the power of the IHS, and consequently the temperature and volume of the pumped liquid [32][33][34].…”

Abstract. Computer models of tape and coil inductors are described, and a comparison of the heating efficiency depending on various parameters is made. The developed computer model was made in the ELCUT 6.0. As a result of the simulation, data on the heating characteristics (depending on the various parameters of the heating elements) are obtained. The average statistical data of a series of experiments with a tape inductor are given. It is shown that for the same parameters (values of inductance and number of wires), the tape version inductor heats up a pipe to a higher temperature (by 5.08%) than the inductor in the coil version in 10 minutes.

“…This was measured at the center, toward all faces and 3.6 cm from the bottom. The electrode, which had an exposed surface area of 1600 cm 2 , was located in the reactor with the 0.01 M methylene blue solution. The solution had its pH adjusted to 10 using 0.1 M NaOH, which was conducted over 2 h to account for adsorption-desorption equilibrium.…”

“…These factors must be improved to reach a massive industrial application of this process. Many other factors can affect the stability of the electrode, such as substrate preparation (in particular with metallic support), the inclusion of a dopant, the solvent involved in the synthesis of the electrodes, the preparation methods and the parameters of thermal decomposition (temperature, heating rate and time) [2].Titanium oxide is one of the most studied materials for photocatalysis applications because it exhibits highly photocatalytic properties and is stable, non-toxic and relatively cheap to produce. The most efficient form of use is via the commercial nanopowders called Degussa P-25 TiO 2 [3].…”

“…Until now, new studies have used electromagnetic induction heating to sinter thermal oxide for photocatalysis. The first one was Mousty et al (1999) [2] that fabricate DSA type electrodes using induction heating. They observed an activation process during cycling voltammetry, which was caused by metallic particles that were left within the coating during rapid decomposition.…”

IntroductionThe remission of toxic contaminants and the use of clean energy, such as the energy of the sun, for this purpose have become popular topics for many research teams. The development of any nation in the world demands a better and major use of energy that must be efficient and have a low environmental impact. Wastewater treatment via an advanced oxidation process, which uses toxic elements from organic sources, is one of the aims of photocatalysis. The process has a high efficiency for neutralizing these toxic compounds and presents the opportunity to produce electrodes that are compatible with the environment [1]. The capability of the electrodes, chemistry process, associated cost effects and the product lifetime are related to the type of material used, and to its structure, stability, and porosity, the substrate material and shape, and the successful adhesion of the coating. These factors must be improved to reach a massive industrial application of this process. Many other factors can affect the stability of the electrode, such as substrate preparation (in particular with metallic support), the inclusion of a dopant, the solvent involved in the synthesis of the electrodes, the preparation methods and the parameters of thermal decomposition (temperature, heating rate and time) [2].Titanium oxide is one of the most studied materials for photocatalysis applications because it exhibits highly photocatalytic properties and is stable, non-toxic and relatively cheap to produce. The most efficient form of use is via the commercial nanopowders called Degussa P-25 TiO 2 [3]. However, the use of these nanopowders generates secondary costs, associate with the need for a high cost filter system to separate the particles from the treated water. To avoid this problem, studies have been conducted to obtain a material supported by a substrate that can be reused, but it must also withstand the reactor conditions during treatment. Simultaneously, these studies have tried to improve the photocatalytic activity of the material by improving the anatase phase stability, porosity distribution, superficial contact area and other variables [4,5,6,7,8]. Numerous substrates have been studied and used to fabricated these types of electrodes, including stainless steel, paper, conductive glass, titanium, ceramic foam, TiO 2 nanoneedle/nanoribbon

Pt and Ir have similar properties, that is, same period and block (6d) of the periodic table, same fcc crystal structure, similar mass and atomic size. The cost of iridium, however, is ca. 60 % lower than that of platinum, so it could be a good substitute for Pt as a catalyst in fuel cells, also if it has to be taken into account that a large use of iridium in fuel cells could noticeably increase its price. Moreover, iridium is stable towards dissolution in acid medium. For these reasons, Pt‐free Ir‐based catalysts and Ir‐containing Pt‐based catalysts have been tested both as anode and cathode materials in low‐temperature acid fuel cells. In this work an overview of the application of Ir and Ir‐containing catalysts as anode materials for hydrogen, methanol and ethanol oxidation, and as cathode materials for oxygen reduction in low‐temperature polymer electrolyte fuel cells fuelled with hydrogen or low molecular weight alcohols, is presented. The more suitable application of iridium in fuel cell electrodes, either as non‐Pt Ir‐based catalysts, maintaining an acceptable catalytic activity, or as co‐catalysts in Pt‐based materials, to increase fuel cell performance simultaneously to a slight decrease of the cost, is discussed.
