摘要: The rates and extents of hydrogen sorption by platinised tungsten trioxide molybdenum have been measured between 273 363 K 3 101 kN m–2. Maximum diffusion coefficients for spilling-over from platinum to the supports estimated. X-Ray diffraction, differential thermal analysis thermogravimetric analysis, e.s.r. i.r. spectroscopy indicate that products this spillover are bronzes molybdenum. These may be represented as HxWO3, where x has a maximum value 0.46, HxMoO3, 1.63. latter violates ranges composition previously accepted bronzes. chemical stability these is discussed in terms their structures.
