Conclusions

  1. 1.

    The surface composition, electronic state, and catalytic activity were studied for monodispersed (33 Å) and polydispersed platinum catalysts on various supports. Platinum in the starting monodispersed catalysts is in an oxidation state from zero to +2. The specific activity of platinum in the hydrogenation of dimethylethynylcarbinol decreases in the series: Pt(0 < n < 2) > Pt(0) > Pt(n⩾2).

  2. 2.

    Ions in the polydispersed catalysts and carbon-containing fragments in the monodispersed catalysts reduce the catalytic activity of platinum in the hydrogenation of dimethylethynylcarbinol.
