如何将羟基MgAl水滑石的阴离子置换为硝酸根离子?这个有难度,你可以尝试一下把固体放在高浓度硝酸根中,降低pH试一下,没有做过 65 mg LDH-CO3 was further treated with 100 mL of aqueous solution containing NaNO3 (0.75 mol) and HNO3 (0.0025 mol) to expel interlayercarbonate ions for 1 day at ambient temperature. The sample LDH-NO3was recovered by centrifugation, washed with deionized water,and vacuum-dried.交流一下,这个是文献中Lanmguir,2012,28,4920中的一个步骤,将碳酸根离子的MgAl水滑石交换为硝酸根离子。其在NaNO3溶液中加入少量的硝酸的目的是?感觉像是利用低浓度的H离子与碳酸根反应消耗掉层间的碳酸根离子,然后硝酸根就可以补充进去。但是这个硝酸的量得注意了,多了会把水滑石给溶解了,查看更多
扫描电化学显微镜能同时记录探针和基底的txt文档吗? 能,用bipotentiostat 比方说The CHI920D Scanning Electrochemical Microscope consists of a digital function generator, a bipotentiostat, high resolution data acquisition circuitry, a three dimension ... 只要设置一下就可以吗,查看更多
