“…In recent years, with the aim of combining the advantages of homogeneous and heterogeneous catalytic processes, nanoparticles have been employed due to their high surface area and facile recovery . Important nano‐heterogeneous supports such as metal oxides, carbon nanotubes, ionic liquids, molecular sieves (SBA‐15, MCM‐41 and MCM‐48), alumina, peptide nanofibers, silica nanoparticles, polymers, graphene oxide and heteropoly acids have been employed for the heterogenization of homogeneous catalysts . Among the various supports, boehmite nanoparticles are considered as outstanding solid supports because of their physical and chemical properties such as excellent thermal and chemical stability, large internal surface area and high concentration of surface OH groups.…”

A boehmite@tryptophan-Pd nanoparticulate catalyst was prepared by a simple, fast and convenient route. The nanomaterial was characterized using various techniques and employed as a thermally stable catalyst for Heck, Stille and Suzuki cross-coupling reactions. Optimized conditions for these reactions are described. The catalyst could be isolated, post-reaction, by simple filtration and recycled for several consecutive cycles without a notable change in its activity.

“…The current decay arises from the adsorption of the poisoning intermediates which are produced in MOR procedure on the catalyst surface. 47,48 Although both the Pt-based catalysts exhibit the still decay of current, the more moderate current density and the higher current density in the steady state condition for Pt/p-MDAB/CF after testing for 3600 s demonstrates the durability and antipoisoning desirability of Pt/p-MDAB modified CF electrode in DMFC.…”

Herein, carbon felt (CF), a porous carbonaceous material is used as an anode in a direct methanol fuel cell (DMFC) application. In order to enhance the electrochemical activity of this electrode, modification of the CF electrode is performed with a polymeric-platinize nanocomposite by a pure electrochemical method. In the modification process, 4-methyl-1,2-diaminobenzene is electropolymerized on the CF surface and then, Pt nanoparticles are electrodeposited on this substrate. Physical characteristics of the synthesized nanocomposite, Pt/p-MDAB/CF, are investigated by field emission scanning electron Microscopy and energy-dispersive Xray spectra. The electrochemical studies such as cyclic voltammetry, chronoamperometry, and electrochemical impedance spectroscopy prove the Pt/p-MDAB/CF superiority over Pt/CF towards methanol oxidation. This superiority that results from the cooperation effect between carbonaceous-polymeric layer and Pt nanoparticles, introduces Pt/p-PDAB/CF as the suitable candidate anode for methanol oxidation reaction (MOR).

“…The most popular anodic materials for alkaline media are nickel [ 106 , 118 , 123 , 124 , 125 , 126 ] and cobalt-based electrodes [ 10 , 106 , 107 , 123 , 126 , 127 ], but other metals, such as gold [ 35 , 57 ], have also been studied. Similar to platinum, their properties can be changed by doping with other elements, both metallic, such as the Pd–Co [ 128 ] system and Ni–Cr 2 O 3 [ 129 ], and nonmetallic, such as borides [ 123 ] and phosphates [ 106 ].…”

The growing climate crisis inspires one of the greatest challenges of the 21st century—developing novel power sources. One of the concepts that offer clean, non-fossil electricity production is fuel cells, especially when the role of fuel is played by simple organic molecules, such as low molecular weight alcohols. The greatest drawback of this technology is the lack of electrocatalytic materials that would enhance reaction kinetics and good stability under process conditions. Currently, electrodes for direct alcohol fuel cells (DAFCs) are mainly based on platinum, which not only provides a poor reaction rate but also readily deactivates because of poisoning by reaction products. Because of these disadvantages, many researchers have focused on developing novel electrode materials with electrocatalytic properties towards the oxidation of simple alcohols, such as methanol, ethanol, ethylene glycol or propanol. This paper presents the development of electrode materials and addresses future challenges that still need to be overcome before direct alcohol fuel cells can be commercialized.
