ENHANCED DISPERSION AND DURABILITY OF PT NANOPARTICLES ON THIOLATED CNT SUPPORT

摘要

Elelctrocatalyst durability and activity have been recently recognized as the most important issues to address before the commercialization of proton exchange membrane fuel cells (PEMFCs). In this manuscript, we present a novel thiolated CNTs (SHCNTs) support by directly linking thiol groups on the CNTs surface for preparation high dispersion and durability Pt/SH-CNTs catalyst. The SH-CNTs have abundant -SH groups on their surface, serving as anchor centers for achieving high Pt dispersion.
