TL;DR: In this article, a hierarchical nanostructured carbon (HNC) with macroporous/mesoporous and mesoporous/microporous structures has been proposed, which has improved mass transport through the macropores/meso-pores and enhanced selectivity and increased specific surface area on the level of fine pore systems through mesopores ormicropores.

TL;DR: The Pt NPs deposited on Vulcan XC-72 (VC) carbon black by the HD-EG strategy show smaller size with more uniform dispersion, higher Pt utilization efficiency, and considerably improved fuel-cell polarization performance compared with the Pt NBP prepared by conventional sodium borohydride reduction or by a microwave-assisted polyol approach.

TL;DR: Ordered hierarchical nanostructured carbon (OHNC) has been fabricated through inverse replication of silica template and explored for the first time to support high loading of Pt nanoparticles as cathode catalyst in proton exchange membrane fuel cells (PEMFC) as discussed by the authors.

TL;DR: TheHCMS carbon supported catalysts exhibited much higher specific activity for methanol oxidation than the commonly used E-TEK catalyst by about 80%, proving that the HCMS carbon capsules are an excellent support for electrode catalysts in DMFC.

TL;DR: In this article, a mesoporous shell with mesopore channels perpendicular to the core surface was synthesized for the first time by adopting silica particles as the core component and by employing Cn-TAB (n = 12, 14, 16, 18).
