Effect of Catalyst and Catalyst Layer Composition on Catalyst Support Durability
Journal of The Electrochemical Society, 2021 Polymer electrolyte membrane fuel cells (PEMFCs) are efficient, zero-emission engines for the automotive sector. However, cost and durability are major barriers for the commercialization of PEMFCs. Degradation of the carbon support in the cathode catalyst layer due to high potential excursions caused by unmitigated events like H2 starvation, or start ...

Imaging Fermi-level hysteresis in nanoscale bubbles of few-layer MoS2
Communications Materials, 2023 The electrical stability and reliability of two-dimensional (2D) crystal-based devices are mainly determined by charge traps in the device defects. Although nanobubble structures as defect sources in 2D materials strongly affect the device performance ...

Oxygen vacancy defects engineering on Cu-doped Co3O4 for promoting effective COS hydrolysis
Green Energy & Environment, 2023 The activation of H2O is a key step of the COS hydrolysis, which may be tuned by oxygen vacancy defects in the catalysts. Herein, we have introduced Cu into Co3O4 to regulate the oxygen vacancy defect content of the catalysts.
