The synthesis of Pt nanocrystals with controlled morphology must have interesting applications in practice, since the catalytic activity for structure-sensitive reactions depends on the orientation of the crystalline facets. Using the obtained morphologically controlled Pt nanoparticles, Pt/Al203 catalysts were prepared and applied for a structure-sensitive reaction, i.e., NO reduction by CH4.

Metal phosphates can be prepared by wet and dry methods. The homogeneous precipitation in aqueous systems is often employed to obtain uniformly sized and well-crystallized particles. The solid reactions can be used for preparation of some metal phosphates however, the particles with controlled morphology are difficult to synthesize. Moreover, the solid reaction consumes more energy than the reaction in aqueous system, except the hydrothermal reaction at elevated temperature. Recently the preparation from aqueous solution at low temperature received attention in view of saving energy and as an application for a wide variety of substances. Therefore the preparation of metal phosphate particles by the precipitation method is described next. Although phosphates include ortho-, pyro-, and polyphosphates, only orthophosphates are dealt with here.
