摘要：

High-yield porous phosphonated tin oxides (SnEDTMP) were successfully synthesized through a facile hydrothermal route with SnCl(4 center dot)5H(2)O as tin source, ethylene diamine tetra(methylene phosphonic acid) (EDTMP) as the organophosphorus and NaOH as the pH regulator. Without any additive template during synthetic process, the obtained product had a high specific surface area of 377 m(2)/g, which was considered to stem from the aggregation of nanoparticles resulting in sufficient void spaces. It was found that the order of NaOH added during synthetic process could effectively dominate the aggregation of nanoparticles such to form tight or loose accumulation, which was the key to successful preparation of highspecific-surface-area phosphonated tin oxides.
