The group VIII metals/TiO[sub 2] systems have received attention in strong metal-support interaction (SMSI) because of its promising potential in controlling the catalytic performance (activity and selectivity) of the supported metal catalysts. Concerning the support, it has been reported that the SMSI behavior strongly depends on the nature and/or environment of the TiO[sub 2]. The nature of the dispersed TiO[sub 2] on other metal oxides should be different from that of bulk TiO[sub 2]. Thus, the metal-support interaction between dispersed TiO[sub 2] and the Pt particle can be expected to be different from that occurring on bulk TiO[sub 2]. In this note, the authors report the evidences for the metal-support interaction between dispersed TiO[sub 2] phase on SiO[sub 2] and supported Pt particles by the combined TPR-TPD technique and butane hydrogenolysis. The two types of the metal-support interactions ('light' SMSI and 'deep' SMSI) playing different roles in H[sub 2] adsorptivity and hydrogenolysis activity of platinum particles are proposed.
