“…Among the various alternative energy resources, fuel cells and batteries − are excellent electrochemical systems that convert the chemical energies of the fuel into electrical energy with zero emission of pollutants at low operating temperature and pressure. Alkaline fuel cell is comprised of two kinds of reactions: (1) cathodic reactions involving reduction of oxygen, commonly known as oxygen reduction reaction (ORR) at the cathode, and (2) oxidation of hydrogen or other fuels like methanol, ethanol, etc. at the anode.…”

The successful commercialization of fuel cells and electrolyzer is limited to the cost and instability issues associated with electrocatalysts (platinum/platinum-based catalysts) used. Hence, there is critical challenge to develop stable, non-platinum-based catalysts with multifunctionality and better durability that can efficiently replace platinum. While a sufficient number of bifunctional catalysts are now known in the literature, development of trifunctional catalyst is rarely reported. Herein, we report the development of nitrogen-doped graphitized carbon-encapsulated Ni nanoparticles-based catalyst (Ni-NC700) from an easy derivable Ni(II)-dimeric complex. Microstructural studies reveal that the catalyst annealed at 700 °C has 4–5 layers of graphene sheets forming a shell surrounding the Ni nanoparticles. This catalyst exhibits outstanding trifunctional catalytic performance with onset potential of 0.86, 1.52, and −0.02 V (vs RHE) for oxygen reduction reaction, oxygen evolution reaction, and hydrogen evolution reaction, respectively. The long-term accelerated durability test and methanol tolerance test confirm better stability and durability of this catalyst than those of the benchmark Pt/C. The development of N-doped graphitized carbon shell-encapsulated Ni nanoparticles from a small binuclear Ni(II) complex will open a new horizon for the synthesis of efficient electrocatalysts with trifunctionality.

“…Fuel cells are electrochemical devices that produce electricity from the energy of a fuel through a highly efficient conversion process, resulting in low emissions and low environmental impact [1]. Between the different types of fuel cell, Direct Alcohol Fuel Cells (DAFC) and more specifically, Direct Methanol Fuel Cells (DMFC), represent a valid alternative for small portable electronic devices and auxiliary power units, due to the high energy density of alcohols, their lightweight and compact nature and their ability for fast recharging [2,3].…”

Platinum (Pt) nanoparticles are deposited on a hybrid support (C-MnO2) according to a polyol method. The home-made catalyst, resulted as Pt/C-MnxO1+x, is compared with two different commercial platinum based materials (Pt/C and PtRu/C). The synthesized catalyst is characterized by means of FESEM, XRD, ICP-MS, XPS and μRS analyses. MnO2 is synthesized and deposited over a commercial grade of carbon (Vulcan XC72) by facile reduction of potassium permanganate in acidic solution. Pt nanoparticles are synthesized on the hybrid support by a polyol thermal assisted method (microwave irradiation), followed by an annealing at 600 °C. The obtained catalyst displays a support constituted by a mixture of manganese oxides (Mn2O3 and Mn3O4) with a Pt loading of 19 wt. %. The electro-catalytic activity towards MOR is assessed by RDE in acid conditions (0.5 M H2SO4), evaluating the ability to oxidize methanol in 1 M concentration. The synthesized Pt/C-MnxO1+x catalyst shows good activity as well as good stability compared to the commercial Pt/C based catalyst.

“…Currently carbon supported Pt nanoparticles are extensively used as electrocatalysts in PEMFCs. However the low durability and stability of Pt/C is considered as one of the primary limiting factors for the oxygen reduction reaction (ORR) in order to commercialize PEMFC S [14][15][16][17]. Recently, Pt alloys with transition metals Pt-M (with M=Fe, Co, Cu, Ni, etc) have attracted attention of researchers in order to increase the performance of Pt-based/C electrocatalysts towards the ORR, as well as the resistance to sintering and corrosion [18][19][20].…”
