Carbon-Supported Pt-Based Alloy Electrocatalysts for the Oxygen Reduction Reaction in Polymer Electrolyte Membrane Fuel Cells: Particle Size, Shape, and Composition Manipulation and Their Impact to Activity

“…1 Polymer electrolyte membrane fuel cells (PEMFCs) are among the most promising candidates for the reliable and efficient conversion of hydrogen, produced from fossil or renewable sources, into electric power in automotive, distributed power generation, and portable electronic applications on a large scale.…”

“…33−35,47−49 In the past several decades, diverse experimental methods have been proposed to synthesize size-dependent, carbon-supported, Ptbased alloy nanoparticle catalysts in a variety of shapes, such as rod, wire, polyhedron, dendrite, dimmer, belt, star, and cage. 11 These experimental strategies have included (1) controlling the size of Pt-based nanocatalysts within a small range of 3−5n m to yield a high electrochemical active area and catalytic activity, (2) controlling the shape of Pt-based catalysts to give more complex morphologies (e.g., a dendritic morphology), (3) obtaining high-index facets in nanocatalysts favoring high activity and stability for fuel cell applications, (4) designing controlled architectures (e.g., textured structure, such as core− shell, Pt skin, or Pt monolayer) for Pt-based catalysts, (5) developing new support materials with high conductivity, chemical stability, and surface area, 50,51 and (6) achieving a uniform distribution of Pt or Pt-alloy nanoparticles on advanced support materials with high conductivity.…”

“…However, energy demand is growing faster, along with expansion of economic activities and prosperity. As of May 2011, the estimated daily demand for electricity was about 5500 MW, whereas the actual average generation capacity was about 4500 MW [18,19]. This gap is largely due to fuel supply shortages, as locally available natural gas is used about 86% for thermal based electricity generation [20].…”

“…However, all these traditional sources of energy face limited supply, and burning fossil fuels can increase the risk of global warming and climate change. Current estimation of the global reserves of fossil fuels suggests that, at today's level of extraction, humans will run out of coal in 2127, crude oil in 2067, and natural gas in 2069 [4].…”
