The most prominent facets of the inverted pyramidlike nano-sized etch pits are the {111}A and {1$\bar{1}$1}B surfaces, which differ in their atomic surface terminations [...] OpenAccess: PDF PDF (PDFA); External link: Fulltext 2018-09-2616:50 [PUBDB-2018-03617] Journal Article/Contribution to a conference proceedings et al Hard X-ray Resonant Ptychography for Chemical Imaging at the Sensitivity Limit 14th International Conference on X-ray Microscopy, XRM2018, SaskatoonSaskatoon, Canada, 19 Aug 2018 - 24 Aug 2018 Microscopy and microanalysis 24(S2), 26 - 27 (2018) [10.1017/S1431927618012564]   Restricted: PDF PDF (PDFA); 2018-08-3116:02 [PUBDB-2018-03329] Journal Article et al Dehydrogenation of Liquid Organic Hydrogen Carriers on Supported Pd Model Catalysts: Carbon Incorporation Under Operation Conditions Catalysis letters 148(9), 2901 - 2910 (2018) [10.1007/s10562-018-2487-0]   Liquid organic hydrogen carriers (LOHCs) have great potential as a hydrogen storage medium needed for a future sustainable energy system. Dehydrogenation of LOHCs requires a catalyst, such as supported Pd nanoparticles.

As most of the carbon nitrides, PTIis usually synthesized by thermal or hydrothermal approaches.We present and discuss an alternative synthesis for PTI whichexhibits a pH-dependent solubility in aqueous solutions.
