微波辅助水热法快速合成介孔磷酸镍
Rapid Synthesis of Mesoporous Nickel Phosphates under Microwave Assisted Hydrothermal Condition
摘要
Abstract
Mesostructured nickel phosphate (MW-NiPO-2) was rapidly synthesized in the presence of cationic surfactant by a microwave assisted hydrothermal process. The synthesis parameters, microwave irradiation temperature and time, OHVP and Ni/P molar ratios of the precursor, were systematically investigated and optimized. The characterizations of the materials obtained by the two different procedures, Sol-Gel method and microwave assisted hydro-thermal process, were carried out by ICP, FT-IR, TEM and N2 physisorption. The results show that MW-NiPO-2 can be obtained at relatively low temperature (60℃). When the microwave radiation temperature was 100℃, the mesostructured phase formed in an extremely short period about 0.25 h. Ordered MW-NiPO-2 can be obtained under microwave irradiation for 1 h at 100℃, when 0H7P and the Ni/P molar ratios of the precursor are 2.0 and 0.7, respectively. In contrast, it took at least 24 h for completion via Sol-Gel method. MW-NiPO-2 and SG-NiPO-2 possess similar structure and composition while MW-NiPO-2 exhibites a worm-like appearance other than piled nanotubes. In comparison with the sample synthesized via Sol-Gel method, MW-NiPO-2 possesses a relatively high BET surface area (334.4 nvVg) and pore volume (0.318 cm3/g).关键词
