“…Carbon materials are normally used as electrode materials owing to their high electrical conductivity and chemical stability. Researchers have reported that electrical properties and band structures have been significantly changed by doping noncarbon hybrid elements into carbon nanostructures [14][15][16][17] . Numerous carbon materials have been used as supports for Pt-based electrocatalysts, such as carbon black, porous carbon, carbon nanotubes (CNTs), fullerenes, graphite nanoplatelets, graphene nanosheets and doped graphene with numerous unique molecular structures and optoelectronic properties, which propose unusual prospects for the development of advanced carbon-based electrocatalysts [18] .…”

A detailed understanding of the electrochemistry of platinum electrodes is of great importance for the electrochemical oxidation of fuels and electrochemical reduction of dioxygen in fuel cells. The Pt(111) facet is the most representative model mimicking Pt nanoparticles and polycrystals for fundamental studies. Herein, we propose a site-specific model accompanied with the typical elementary steps of the electrochemistry of Pt (111) in non-adsorbing electrolyte within the potential range between 0.05 and 1.15 V versus reversible hydrogen electrode. Simulations were conducted at different scanning rates based on the kinetics models. We reproduce all the anodic and cathodic peaks observed in the reported experimental curves. These results demonstrate the underlying mechanisms of the peak formation in different potential regions.probably affects the surface reactions. In the current simplified model, mass transfer was not considered. However, the trend of peak shifting is the same with experimental data, which is sufficient and reasonable to do qualitative analyses. Compared Figure 2. Comparison of the simulated (red solid) with experimental (blue dashed) CV curves (a, c, e, g). The experimental data were extracted from the reference. [29] The coverage of the surface species corresponding to the simulated CV curves at different scan rates: (b) 0.005 V s À 1 , (d) 0.05 V s À 1 , (f) 0.5 V s À 1 , (h) 5 V s À 1 . Each curve in a color contains the forward and backward scan labeled with arrow. In the case of the curve without arrow, the forward and backward scans overlap.

“…In particular, direct methanol fuel cells (DMFCs) are a promising storage system due to their high volumetric energy density, low cost, and ease of handling and storage of liquid fuel . Besides hydrogen‐fed fuel cells, methanol has been considered as a favorable option due to its safe handling and storage, high energy density, and availability . Despite all the advantages, commercialization of DMFC is yet to be proven due to the problems arising from the stability and life cycles of electrocatalysts.…”

Transition metal oxides have attracted attention as promising electrode materials for energy storage and conversion devices with high electrochemical activity and stability. In this study, a simple and cost-effective solvothermal synthesis of rectangular 3D CuCo 2 O 4 hollow tubes have been developed for methanol electro-oxidation application. Electrochemical analysis shows that CuCo 2 O 4 hollow tubes exhibit superior electrochemical performance in terms of current density and cycling stability, with 75 mA cm À 2 and 90 % retention rate after 1000 cycles, respectively. The high electrochemical performances are mainly due to the morphological structure of CuCo 2 O 4 hollow tubes, which possess high surface area and porosity, resulting to a faster electron-ion transfer, enhanced reactivity and stability. Given that the synthesis of CuCo 2 O 4 hollow tubes involve a facile and cost-effective technique, the present approach, thus, opens a new era to novel materials for large-scale processes in different electrochemical applications.
