Pentlandite rocks as sustainable and stable efficient electrocatalysts for hydrogen generation
Autor: 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
Publikováno v: Nature Communications, Vol 7, Iss 1, Pp 1-8 (2016)
There are comparable structural properties between the natural enzyme [FeNi]-hydrogenase and the natural ore, pentlandite. Here the authors, inspired by these similarities, use the mineral as a ‘rock’ electrode, and evaluate its electrocatalytic

Inspired by our recent finding that Fe4.5Ni4.5S8 rock is a highly active electrocatalyst for HER, we set out to explore the influence of the Fe:Ni ratio on the performance of the catalyst. We herein describe the synthesis of (FexNi1–x)9S8 (x = 0–

Co 3 O 4 @Co/NCNT Nanostructure Derived from a Dicyanamide‐Based Metal‐Organic Framework as an Efficient Bi‐functional Electrocatalyst for Oxygen Reduction and Evolution Reactions
Autor: Justus Masa, Bharathi Konkena, Tapas Kumar Maji, Nivedita Sikdar, Wolfgang Schuhmann
Publikováno v: Chemistry – A European Journal. 23:18049-18056
There has been growing interest in the synthesis of efficient reversible oxygen electrodes for both the oxygen reduction reaction (ORR) and the oxygen evolution reactions (OER), for their potential use in a variety of renewable energy technologies, s

Synthesis of nano-porous carbon and nitrogen doped carbon dots from an anionic MOF: a trace cobalt metal residue in carbon dots promotes electrocatalytic ORR activity
Autor: Sohini Bhattacharyya, Bharathi Konkena, Wolfgang Schuhmann, Tapas Kumar Maji, Kolleboyina Jayaramulu
Publikováno v: Journal of Materials Chemistry A. 5:13573-13580
Metal–organic frameworks (MOFs) are effective self-sacrificial templates for the synthesis of carbon materials owing to their innate porosity, high carbon content and ease of heteroatom doping. A MgII based anionic MOF {[Mg3(ndc)2.5(HCO2)2(H2O)]·[

Metallic NiPS3@NiOOH Core–Shell Heterostructures as Highly Efficient and Stable Electrocatalyst for the Oxygen Evolution Reaction
Autor: Ilya Sinev, Ralf Drautz, Wolfgang Schuhmann, Wei Xia, Justus Masa, Martin Muhler, Jörg Koßmann, Bharathi Konkena, Alexander Botz
Publikováno v: ACS Catalysis. 7:229-237
We report metallic NiPS3@NiOOH core–shell heterostructures as an efficient and durable electrocatalyst for the oxygen evolution reaction, exhibiting a low onset potential of 1.48 V (vs RHE) and stable performance for over 160 h. The atomically thin
