“…Pt-CHO + Pt-OH + 2OH -→ 2Pt + CO2 + 2H2O + 2e - (11) In spite of the above-proposed mechanisms of MOR in acidic or alkaline media, it is still challenging to accurately probe the actual MOR process, especially at a real-time and molecular level. Moreover, since so many intermediates are produced during the catalysis [49,[64][65][66][67][68][69][70] nanocubes, [71] nanoflowers, [72,73] nanowires, [74,75] nanosponges, [76] nanoframes [77] . Besides, nanoparticles with superior durability in long-term and extreme operation condition in a full stack DMFC.…”

“…Pt-based catalysts are still one of the most popular electrocatalysts for MOR in the DMFCs anode for their outstanding catalytic properties. A large amount of research has been conducted on the rational design of Pt monometallic or Pt-carbon composite catalysts with desired morphologies and microstructures for MOR, such as nanoparticles, [49,[64][65][66][67][68][69][70] nanocubes, [71] nanoflowers, [72,73] nanowires, [74,75] nanosponges, [76] and nanoframes. [77] Besides, significant efforts have been devoted to developing novel Pt-based bimetallic or multimetallic nanocatalysts for improved CO tolerance.…”

Various metal-based anode catalysts have been extensively studied and utilized for the essential methanol oxidation reaction (MOR), due to their superior electrocatalytic performance. At present, especially with the rapid advance of nanotechnology, enormous efforts have been exerted to further enhancing the catalytic performance and minimizing the use of precious metals. Constructing multicomponent metal-based nanocatalysts with precisely designed structures can achieve this goal by providing highly tunable compositional and structural characteristics, which is promising for the modification and optimization of their related electrochemical properties. The recent advances of the metal-based electrocatalytic materials with rationally designed nanostructures and chemistries for MOR in DMFCs are highlighted and summarized herein. The effects of the well-defined nanoarchitectures on the improved electrochemical properties of the catalysts are illustrated. Finally, conclusive perspectives are provided on the opportunities and challenges for further refining the nanostructure of the metal-based catalysts and improving the electrocatalytic performance, as well as the commercial viability.
