Confining Pt nanoparticles in porous carbon structures for achieving durable electrochemical performance.

Nanoscale

Yang C, Zhou M, Xu Q.
PMID: 25171499
Nanoscale. 2014 Oct 21;6(20):11863-70. doi: 10.1039/c4nr03555k. Epub 2014 Aug 29.

Carbon-supported Pt catalysts have been widely employed as electrocatalysts for energy storage/conversion applications, but have encountered challenging instability issues. In this work, we investigated the degradation behaviors of pore-confined and surface-located Pt nanocatalysts, employing hollow porous carbon spheres with...

On local convergence analysis of inexact Newton method for singular systems of equations under majorant condition.

ScientificWorldJournal. 2014;2014:498016. doi: 10.1155/2014/498016. Epub 2014 Aug 28.

We present a local convergence analysis of inexact Newton method for solving singular systems of equations. Under the hypothesis that the derivative of the function associated with the singular systems satisfies a majorant condition, we obtain that the method...

K-enriched WO3 nanobundles: high electrical conductivity and photocurrent with controlled polarity.

ACS applied materials & interfaces

Hu Z, Ji Z, Lim WW, Mukherjee B, Zhou C, Tok ES, Sow CH.
