The penetration of the liquid phase requires the elimination of air from the pores. If the pore radius is very small, capillary pressure is much larger than the pressure of the entrapped air; compressed air dissolves or escapes from the solid through larger pores.

Sometimes, the mechanical strength of the support is not sufficient to withstand forces imposed by the transitory formation of bubbles and the catalyst grains may burst.

This can be remedied by impregnation under vacuum or addition of a surfactant to the solution. Before water filling, air can be replaced by a watersoluble gas like ammonia to avoid gas bubbles in the pores.

A possible reason can be that the ruthenium species dispersed well on the surface of CeO2 nanoparticles or incorporated into the CeO2 lattice to form solid solution. EDS According to FFT analysis, it can be found that three kinds of lattice fringe directions attributed to , and of CeO2 were observed for the both samples, which have a respective interplanar spacing of 0. However, the lattice fringes of RuO2 and TiO2 are very difficult to be found likely due to the similar crystal structure and interplanar spacing with CeO2.

Similarly, RuO2 also might be present as a noncrystalline phase. In the case of proper wetting no excess of solution remains outside the pore space and the procedure is also called dry or incipient wetness impregnation.

Wet impregnation should be avoided when the interaction between precursor and support is too weak to guarantee the deposition of the former.

Признаков какого-либо входа в нее не было заметно. Пока они шли через Парк — эскорт при этом держался в почтительном отдалении и переговаривался взволнованным шепотом,– Олвин взвешивал свой следующий шаг. — А ты все еще надеешься не допустить до .
