“…However, the choice of a suitable support is essential to achieve a better cell performance (Dwivedi et al, 2018). Many studies were carried out on applying conjugated polymers with high conductivity such as PANI (Ivanova et al, 2016), PPy (Ghosh et al, 2017a), poly-para-phenylendiamine (PpPD) [The electrocatalytic oxidation of methanol on a carbon paste electrode modified by poly (para-phenylenediamine) and Nickel particles, 2019], poly-ortho-phenylendiamine (PoPD) (Gajendran and Saraswathi, 2013;Parsa and Amanzadeh-Salout, 2016;Halim et al, 2019a), PEDOT (Nakova et al, 2019) as support of metallic nanoparticles.…”

Sustainable energy development is a major challenge, particularly when considering population increase, rising energy demands resulting from the excessive use of nonrenewable fossil fuels, and growing consequences on global pollution and climate change. It is critical to continue to develop new sources of renewable and clean energy. Direct alcohol fuel cell (DAFC) represents a technological approach that meets all the requirements in terms of energy conversion with good electrical efficiency and lower emissions of pollutants. However, it largely suffers from the poisoning of the anode catalyst caused by the accumulation of intermediate products. In this context, this review is devoted to discussing the recent progress in anode catalysts based on conducting polymers (CPs) materials for direct alcohol fuel cells, especially direct methanol and ethanol fuel cells, from the viewpoint of synthesis techniques, morphology, and catalytic performance. In the first part of this review, we will explore the most commonly used methods for preparing metal-conducting polymer-based nanocomposites, including the key factors influencing their morphology regardless of the application. The catalytic performances of mono-, bi-, and tri-metal catalysts deposited on conducting polymer-based supports for the electrooxidation of methanol and ethanol reactions are examined in detail in the second and third parts of this review. We also highlight the effect of the introduction of carbon nanomaterials into conducting polymer supports on the electrical properties and on the performance of the catalysts. Development of anode materials using nanostructured conducting polymers-based support plays a vital role in reducing catalyst loadings and should therefore shed light on the wide-scale commercialization of DAFCs. In a nutshell, this review will give readers a thorough understanding of the principles of direct alcohol fuel cells, new advancements in electrode materials based on non-precious metals, and the main challenges that should be dealt with.

Bimetallic transition-metal phosphides are gradually evolving as efficient hydrogen evolution catalysts. In this study, graphene-coated MoP and bimetallic phosphide (MoNiP) nanoparticles (MoP/MoNiP@C) were synthesized via one-step straightforward high-temperature calcination and phosphating process. The precursor was obtained from polyaniline, Ni2+ ions, and phosphomolybdic acid hydrate (PMo12) by solvent evaporation. As expected, MoP/MoNiP@C manifests excellent hydrogen evolution activity with a low overpotential of 134 mV at 10 mA cm–2 and a small Tafel slope of 66 mV dec–1. Furthermore, MoP/MoNiP@C exhibits satisfactory stability for 24 h in the acid electrolyte. The outstanding catalytic performance can be attributed to the synergistic effect of MoP and MoNiP nanoparticles, the graphene coating protecting MoP and MoNiP from corrosion, as well as an increase in the number of active sites because of porous structures. This work can provide the experimental foundation for the simple synthesis of bimetallic phosphates with remarkable hydrogen evolution performance.
