Unsupported NiWS catalysts formed in situ by thermal decomposition of the synthesized sulfonium thiosalt were studied in hydrodeoxygenation of diphenyl ether. The influence of the reaction temperature and time, H2 pressure, and gravimetric water content of the system on the catalyst activity and reaction product composition was studied. The diphenyl ether conversion reaches 100% already in 2 h after the start of the process and at an H2 pressure of 1 MPa. The catalysts obtained were characterized by high-resolution transmission electron microscopy and X-ray photoelectron spectroscopy. The water addition to the system does not noticeably influence the activity of the formed catalysts but leads to changes in the morphology of sulfide particles and phase composition of the surface layer of the catalysts.
