以(NH4)10W12O41·5H2O,HCl,柠檬酸和N2H4·2HCl为原料,利用水热法制备了铵钨青铜纳米晶,研究了HCl浓度对所制备铵钨青铜(NH4)xWO3纳米晶的影响.实验证实,当HCl浓度低于7.67 mg·mL-1时产物为[001]取向生长的纯六方相(NH4)xWO3纳米棒;HCl浓度增高(9.86和12.05 mg·mL-1)时会生成杂相WO3·H2O和(NH4)10W12O41.吸附实验表明,(NH4)xWO3纳米晶对亚甲基蓝(MB,模拟有机染料污染物)具有优异的吸附性能.并且,吸附在(NH4)xWO3表面的染料经加热处理即可除去,且加热处理后的纳米晶对亚甲基蓝仍具有良好的吸附性能.
