| 英文摘要 | nanometer mgo samples with high surface area, small crystal size, and mesoporous texture were synthesized by thermal decomposition of mgc2o4 center dot 2h(2)o, which was prepared by solid-state chemical reaction between h2c2o4 center dot 2h(2)o and mg(ch3coo)(2)center dot 4h(2)o. the existence of steam accelerated the sintering of mgo during the decomposition process and mgo with surface area as high as 412 m(2)/g was obtained through calcining the precursor in flowing dry nitrogen at 520 degrees c for 4 h. the samples were characterized by x-ray diffraction, n-2 adsorption, transmission electron microscopy, thermogravimetry, and differential thermal analysis. the as-prepared mgo was composed of nanocrystals with a size of 4-5 nm and formed a wormhole-like porous structure. in addition, the mgo had good thermal stability, and its surface area was still 357 and 153 m(2) /g after calcination at 600 and 800 degrees c for 2 h, respectively. compared with the mgo sample prepared by the precipitation method, mgo prepared by the solid-state chemical reaction has similar pore size distribution, surface area, and crystal size. the solid-state chemical method has the advantages of low cost, low pollution, and high yield; therefore it appears to be a promising method for the manufacture of nanometer mgo in industry. |
