| 中文摘要 | the synthesis of sio2 coated ceo2 nanoparticles by humid solid state reaction at room. temperature is described. transmission electron microscope results show that ceo2 particles were coated with a layer of sio2. binding energy of ce 3d(5/2) was shifted from 883.8 to 882.8 ev after coating in the xps ce 3d spectra. this confirms the chemical bond formation between sio32- and ce4+. because the surface photovoltage property of ceo2 nanoparticles that were used as core materials in the experiment approaches to that of ceo2 macroparticles, peak p2 (electron transition from 0 2p on surface to ce 4f) disappeared in the surface photovoltage spectrum of ceo2 nanoparticles. also, the effect of sio2 on the electron transition from 0 2p to ce 4f results in the lowering of surface photovoltage response intensity of p1 peak (electron transition from 0 2p in bulk to ce 4f). |
