·Òë²»¾«£¬½ö¹©²Î¿¼¡£ The TEM (a, b) of X microns ball, HRTEM (c, d) chart and x = 0.1 mol/L, the TEM (e), HRETEM (f) chart of the production X were achieved under the conditions of 120 ¡æ, 24 h. According to the experimental results, we proposed the mechanism that x hollow microns ball might be formed: first, ethylenediamine and X solution were mixed to form complexes [x (en) 2] 2 +, then en generated by complexes dissociation reacted with CS2 penetrated through oil film, as reaction (2), polycondensation reaction (3) by intermediate generated in reaction (2) produced H2S,which reacted with X as the S2- source to generate XS nanocrystalline, as reaction (4). The possible reactions were as follows: |
