Synthesis of single-crystalline lead sulfide nanoframes and nanorings
Sascha Kull, Leonard Heymann, Ana B. Hungria +1
We present a colloidal synthesis strategy to obtain single-crystalline PbS nanorings. By controlling the ripening process in the presence of halide ions, a transformation of initia…
Field effect and photoconduction in Au25 Nanoclusters Films
Michael Galchenko, Andrés Black, Leonard Heymann +1
Quantum confined Au nanoclusters exhibit molecule-like properties, including atomic precision and discrete energy levels. The electrical conductivity of Au nanocluster films can va…
Molecular Doping of Electrochemically Prepared Triazine-based Carbon Nitride by 2,4,6-Triaminopyrimidine for Improved Photocatalytic Properties
Leonard Heymann, Sophia Bittinger, Christian Klinke
The copolymerization of melamine with 2,4,6-triaminopyrimidine (TAP) in an electrochemical induced polymerization process leads to the formation of molecular doped poly (triazine i…
Colloidal Lead Iodide Nanorings
Eugen Klein, Leonard Heymann, Ana B. Hungria +2
Colloidal chemistry of nanomaterials experienced a tremendous development in the last decades. In the course of the journey 0D nanoparticles, 1D nanowires, and 2D nanosheets have b…
A New Synthesis Approach for Carbon Nitrides: Poly (Triazine Imide) and Its Photocatalytic Properties
Leonard Heymann, Bjoern Schiller, Heshmat Noei +2
Poly (triazine imide) (PTI) is a material belonging to the group of carbon nitrides and has shown to have competitive properties compared to melon or g-C3N4, especially in photocat…
