ZrO 2 –Y 2 O 3 –TiO 2 system. While the thermal conductivity was influenced by the composition the specific heat of the ceramics was unaltered as the TiO 2 content changed [ 39 ]. Other Zirconia containing composites, containing phosphorous oxide
] were tested in oxidation of acetic acid. During CWAO of formic acid, acetic acid and phenol carried out in a trickle bed reactor over various Ru/TiO 2 catalysts [ 2 ], complete oxidation of formic acid was observed with no catalyst deactivation. As a
. [ 19 ] evaluated the cool storage capacity of the BaCl 2 /H 2 O solution with suspended TiO 2 nanoparticles. It showed the cool storage/supply rate and the cool storage/supply capacity both increased higher than those of BaCl 2 /H 2 O solution without
/inorganic composites such as PANI/TiO 2 , PANI/Fe 3 O 4 , PANI/Fe 2 O 3 , PANI/MnO 2 , PANI/ZrO 2 , PANI/Co 3 O 4 , PANI/Al 2 O 3 , and PANI/NiO have been published in the literatures [ 1 – 8 ]. PANI usually combined with inorganic components to form composites to

CO on the Pd surface was decreased by use of acidic support, and a high hydrogenation activity in the presence of CO was attained. Similarly, Ino [ 14 ] used Pd/TiO 2 –Al 2 O 3 catalysts and found that the support acidity improved the hydrogenation
ZrO 2 , TiO 2 , CeO 2 and binary oxide supports for CuO and Pt catalysts have provided excellent catalytic properties in complete CO and VOCs oxidation [ 4 , 9 ]. In this paper, mesoporous nanostructured Ce 0.8 Zr 0.2 O 2 oxides were prepared by the
local samples were investigated through chemical analysis. The chemical analysis of clay samples was carried out and the data were presented in Table 1 . Na 2 O, K 2 O, Fe 2 O 3 , and TiO 2 are present only very small amounts in sepiolite sample. The
