“…In a nitrogen atmosphere, Cu(NO 3 ) 2 ·3H 2 O first melts at 116-152 °C, converts to β-Cu 2 (OH) 3 NO 3 at 199-217 °C, and decomposes to CuO at 263-310 °C [42]. CuO decomposes at >450 °C to Cu 2 O [43] and finally decomposes to metallic copper at higher temperatures. It is also reported that Cu 2 O reduces directly to Cu at >525 °C [44].…”

Adsorption of sulfur compoundsby porous materials is an effective way to produce cleaner diesel fuel.In this study, adsorption of refractory thiophenic sulfur compounds, i.e., benzothiophene (BT), dibenzothiophene (DBT), and 4,6-dimethyldibenzothiophene (4,6-DMDBT) in single-solute systems from n-hexane solutions onto metal-impregnated activated carbons was investigated. A hydrogen-treated activated carbon fiber was selectively loaded with Ni, NiO, Cu, Cu 2 O, and CuO species to systematically assess the impact of each metal species on the adsorption of thiophenic compounds (TC). Metal-loaded adsorbents had the same total metal contents and similar microporosities, but contained different types of copper or nickel species. All metal-loaded adsorbents showed enhanced adsorption of tested TC. Cu 2 O-or NiO-loaded adsorbents exhibited the highest uptakes, due to more specific interactions between Cu + or Ni 2+ species and TC molecules. The theoretical monolyer coverage of TC on the exposed Cu + sites was estimated and compared with that calculated from the experimental data. Results suggested catalytic conversion of TC molecules to other compounds on the Cu + sites, followed by adsorption of reaction products onto the carbon surface or multilayer accumulation of TC molecules on the Cu + sites. TC adsorption uptake of the majority of adsorbents followed the order of: 4,6-DMDBT > DBT > BT due to higher intensity of specific and non-specific interactions of larger TC molecules with adsorbents.

“…Ni(NO 3 ) 2 ·6H 2 O is reported to decompose to NiO at >350 °C [43]. A high temperature (800 °C) and a reductive atmosphere (H 2 ) were selected to ensure complete reduction of NiO to metallic nickel.…”
