Although hydrodesulfurization is a key process in the chemical industry, a deep understanding of the catalyst structure under real reaction conditions is lacking. Here, the authors combine theoretical calculations with high-pressure scanning tunnelin

Capturing and converting CO2 in photoactive, porous materials to mimic photosynthesis is not only an appealing but also an important approach to combat increasing CO2 concentrations. Porphyrinic Zr-based metal-organic frameworks (MOFs) incorporate a

Reducible supports can affect the performance of metal catalysts by the formation of suboxide overlayers upon reduction, a process referred to as the strong metal–support interaction (SMSI). A combination of operando electron microscopy and vibrati

Ni sulfide (NiS x ) crystals dominate the TEM images and STEM-EDX elemental maps of used Ni-Mo and Ni-W hydrotreating catalysts. Crystal sizes ranging from about 5 to over 100 nm in diameter are observed not only in severely deactivated catalysts aft

The hydrodesulfurization process is one of the cornerstones of the chemical industry, removing harmful sulfur from oil to produce clean hydrocarbons. The reaction is catalyzed by the edges of MoS2 nanoislands and is operated in hydrogen-oil mixtures

Brominated benzylpolystyrene (BrBPS) is a fire safety polymer, which imparts flame retardancy in a variety of styrenic polymers and resins. In this study, the individual components of BrBPS were evaluated using a novel screening process to inform var

The 1H NMR spectra of 3-(triethoxysilyl)propanenitrile (1), 3-(trichlorosilyl)propanenitrile (2) and trichloropropylsilane (3) show that these systems are present to about 40% in the gauche conformer. For 1 and 3, the solvent dependence of the confor
