Objetos Con Ca Co Cu Vrogue Co A series of copper catalysts with a core–shell or tubular structure containing various contents of cu, cu2o, and cuo were prepared via controlled oxidation of cu nanowires (nws) and used in the synthesis of dimethyldichlorosilane (m2) via the rochow reaction. the cu nws were prepared from copper (ii) nitrate using a solution based reduction method. the samples were characterized by x ray. The two spectra are fitted into two chemically distinct components by a gaussian function. they are centred at 397.5 ev and 399.7 ev for sample 1 and 397.7 ev and 399.5 ev for sample 2. peak 1 at.

The cu species in cu 2 o sample is ambiguously cu and that in cu 2 o 3 sample is indeed cu 0 as evidenced from their auger cu lmm peaks at 570.1 and 569.2, respectively [25], [52]. the surface limited range of xps analysis is reasonable to show only cu 0 within the cu 2 o 3 sample because cu 2 o surface is almost fully covered by cu nps after. The effect of different crystal phases, i.e. spinel phase (cumn 2 o 4) and amorphous phase (cu 0.2 mno x), was explored in cu mn catalytic ozonation of toluene.the toluene removal efficiency followed the order of cu 0.2 mno x (91.2%) ˃ cumn 2 o 4 (74.5%) ˃ commercial catalyst cu 0.3 mno x (70.3%) in 130 min, and the higher co 2 yield (67.6%) could be also observed using cu 0.2 mno x.

A series of hydrotalcite like (htl) compounds of the general composition (cu,zn)1−xalx(oh)2(co3)x 2·m h2o was prepared with a fixed cu:zn ratio of 70:30. phase pure samples could be obtained for 0.3 ≤ x ≤ 0.4. the htl precursors thermally decompose in multiple steps. after dehydration and dehydroxylation amorphous materials were obtained at 330 °c. phase segregation during this mild.
