Seawater Electrolysis Using All-PGM-Free Catalysts and Cell Components in an Asymmetric Feed

, 2023
In arid coastal zones, direct seawater electrolysis appears particularly intriguing for green hydrogen production. State-of-the-art direct seawater electrolyzers, however, show unsatisfactory performance and rely on large amounts of platinum-group metals

Evolution of bacterial phosphoglycerate mutases: non-homologous isofunctional enzymes undergoing gene losses, gains and lateral transfers. [PDF]

PLoS ONE, 2010
The glycolytic phosphoglycerate mutases exist as non-homologous isofunctional enzymes (NISE) having independent evolutionary origins and no similarity in primary sequence, 3D structure, or catalytic mechanism.

Performance optimization of PGM and PGM-free catalysts in anion-exchange membrane fuel cells [PDF]

, 2022
This study focuses on H2-O2 operando AEMFC performance based on several platinum group metal (PGM) and PGM-free catalysts. Specifically, we evaluate the AEMFC performance of commercial PtRu/C, as-synthesized PtRu/C, and Pd-CeO2/C catalysts as anodes and ...

Effects of Ink Formulation on the Structure and Performance of PGM-Free Catalyst Layer in PEMFCs [PDF]

, 2021
Platinum group metal (PGM) catalysts are the major electrocatalysts for oxygen reduction reaction (ORR) in the polymer electrolyte membrane fuel cells (PEMFCs). The cost becomes unaffordable if the PEMFC is in massive application.
