“…[9,10] To overcome these problems and to increase the catalytic activity of electrocatalysts, the use of support materials is one of the most important issues. [10] As support material in AOR studies, It is seen that structures such as carbon allotropes, [11] carbides, metal oxides, or nanofibers are mostly used. Among these structures, nanofibers are one-dimensional nanostructures, and such structures can exhibit a high surface/volume ratio, small pore size, mechanical, and superior electronic properties.…”

In this study, Pd@TiO2 nanostructure is formed by using TiO2 fibers obtained by the electrospinning method and chemical reduction method, and this nanostructure is used in C2, and C3 alcohol oxidation studies as an application. In addition, TiO2 is compared with the Pd catalyst to investigate the effect of TiO2. In the results obtained, peak current values of 193 and 66.7 mA cm−2 for ethanol oxidation and 127.38 and 36.18 mA cm−2 for 2‐propanol oxidation are observed for Pd@TiO2 and Pd catalysts, respectively. With the addition of TiO2 to the structure, the electrocatalytic activity of C2 and C3 alcohol oxidations increases 3–3.5 times and contributes to the onset potential at an earlier potential. It also shows higher durability and stability in long‐term tests. Moreover, the addition of TiO2 to the structure enhances the electrocatalytic activity and provides high current density and long‐term stability in alcohol oxidation. These results show that fibrous structures in combination with metals improve the effect of catalysts and exhibit high potential for their application in alcohol fuel cells.

A constant increase in global emission standard is causing fuel cell (FC) technology to gain importance. Over the last two decades, a great deal of research has been focused on developing more active catalysts to boost the performance of high‐temperature polymer electrolyte membrane fuel cells (HT‐PEMFC), as well as their durability. Due to material degradation at high‐temperature conditions, catalyst design becomes challenging. Two main approaches are suggested: (i) alloying platinum (Pt) with low‐cost transition metals to reduce Pt usage, and (ii) developing novel catalyst support that anchor metal particles more efficiently while inhibiting corrosion phenomena. In this comprehensive review, the most recent platinum group metal (PGM) and platinum group metal free (PGM‐free) catalyst development is detailed, as well as the development of alternative carbon (C) supports for HT‐PEMFCs.

“…4,5 Due to the problems of H 2 as a fuel in proton-exchange membrane fuel cells (PEMFCs), such as its transportation and storage, in recent years, researchers have focused on direct liquid fuel cells (DLFCs). Different liquid fuels can be used in DLFCs, 6 such as ethanol, [7][8][9] methanol, [10][11][12] borohydride, 13,14 hydrazine, [15][16][17] and formate. 18,19 Ethanol oxidation has more steps than the methanol oxidation reaction.…”
