摘要
The application of kinetically controlled vapor diffusion catalysis to the synthesis of films of chromium phosphate produces a novel, nanostructured film morphology. The resulting material consists of a thin, flat backplane (3 mu m thick) with needles of CrPO4 center dot 6H(2)O projecting from one surface of the film. The reaction process occurs at low temperature (25 degrees C) and mild pH. (c) 2007 Elsevier Masson SAS. All rights reserved.
