    Microspherical ReS2 as a High-Performance Hydrodesulfurization Catalyst

    An unsupported microspherical ReS2 catalyst, consisting in self-assembled nano-layers, was evaluated in the hydrodesulfurization (HDS) of 3-methylthiophene showing an excellent catalytic activity. The samples wer...

    Thermal behaviour of benzenesulfenamides and of their chromium carbonyl complexes

    Benzenesulfenamides with the formula R-S-N-(R′)2 (R=C6H5 andR′=NC4H8O, C7H7 and C6H11) and their chromium carbonyl complexes were studied by means of TG and mass spectrometric methods. The thermal behaviour of th...
