Journal ArticleDOI
Pentlandite rocks as sustainable and stable efficient electrocatalysts for hydrogen generation.
Bharathi Konkena,Kai junge Puring,Ilya Sinev,Stefan Piontek,Oleksiy Khavryuchenko,Johannes P. Dürholt,Rochus Schmid,Harun Tüysüz,Martin Muhler,Wolfgang Schuhmann,Ulf-Peter Apfel +10 more
TL;DR: The superior hydrogen evolution performance of pentlandites as ‘rock' electrode labels this ore as a promising electrocatalyst for future hydrogen-based economy.
Journal ArticleDOI
Enzyme-Inspired Iron Porphyrins for Improved Electrocatalytic Oxygen Reduction and Evolution Reactions.
Lisi Xie,Xue-Peng Zhang,Bin Zhao,Ping Li,Jing Qi,Xinai Guo,Bin Wang,Haitao Lei,Wei Zhang,Ulf-Peter Apfel,Rui Cao +10 more
TL;DR: In this paper, an enzyme-inspired Fe porphyrin 1 as an efficient catalyst for both ORR and OER was reported. But the performance of the enzyme-based catalysts was limited by the fact that it was not shown to be efficient for the oxygen evolution reaction (OER).
Journal ArticleDOI
Metal-Organic-Framework-Supported Molecular Electrocatalysis for the Oxygen Reduction Reaction.
Zuozhong Liang,Hongbo Guo,Guojun Zhou,Kai Guo,Bin Wang,Haitao Lei,Wei Zhang,Haoquan Zheng,Ulf-Peter Apfel,Rui Cao +9 more
TL;DR: In this article, metal-organic framework (MOF)-supported Co porphyrins were used as air electrode catalysts in Zn-air batteries, which exhibited equal performance to that with Pt-based materials.
Journal ArticleDOI
Influence of the Fe:Ni Ratio and Reaction Temperature on the Efficiency of (FexNi1–x)9S8 Electrocatalysts Applied in the Hydrogen Evolution Reaction
Stefan Piontek,Corina Andronescu,Corina Andronescu,Aleksandr Zaichenko,Bharathi Konkena,Kai junge Puring,Bernd Marler,Hendrik Antoni,Ilya Sinev,Martin Muhler,Doreen Mollenhauer,Beatriz Roldan Cuenya,Beatriz Roldan Cuenya,Wolfgang Schuhmann,Ulf-Peter Apfel +14 more
TL;DR: In this article, the influence of the Fe:Ni ratio on the performance of the catalyst was explored and it was shown that the increase in the iron or nickel content, respectively, lowers the activity of the electrocatalyst toward HER.
Journal ArticleDOI
A structural view of synthetic cofactor integration into [FeFe]-hydrogenases.
Julian Esselborn,Norifumi Muraki,Kathrin Klein,Vera Engelbrecht,Nils Metzler-Nolte,Ulf-Peter Apfel,Eckhard Hofmann,Genji Kurisu,Thomas Happe +8 more
TL;DR: Crystal structures of semisynthetic [FeFe]-hydrogenases with variations in the [2Fe] cluster show little structural differences despite strong effects on activity.
