Abstract：
Silica nanochannel membranes, particularly those consisting of highly ordered and vertically aligned channels (designated as SNM for simplicity in this review), have recently emerged as a class of attractive nanomaterials, because of their controllable and tunable pore structure, large surface area, high selectivity, and permeability, as well as diverse promising applications. This review describes recent developments in the field of SNM and their applications in electrochemical analysis and molecular separation. We summarize and highlight (i) the synthesis and functionalization strategies; (ii) the basic properties with emphasis on the selectivity and permeability, and factors affecting them; (iii) electrochemical analysis based on the electrode-supported SNM in terms of electrostatic, hydrophobic extraction, size-exclusion, and anti-fouling effects; (iv) molecular separation using the flow-through SNM according to molecular properties (size, charge, and lipophilicity) and gated, rectified molecular transport. Finally, we present an outlook and perspective on the further applications of SNM in the relevant fields.
摘要：
二氧化硅纳米通道膜，特别是那些由高度有序和垂直对齐的通道组成的通道（在本评论中为简单起见，指定为SNM），最近成为一类有吸引力的纳米材料，由于其可控和可调的孔结构，大表面积,高选择性,和渗透性，以及各种有前途的应用。本文介绍了SNM领域的最新进展及其在电化学分析和分子分离中的应用。我们总结并强调（i）合成和官能化策略；（ii）基本性能，重点是选择性和渗透性，以及影响它们的因素；（iii）基于电极支持的SNM在静电方面的电化学分析，疏水萃取,尺寸排除，和防污作用；（iv）根据分子特性（尺寸，charge,和亲脂性)和门控，整流分子传输。最后,我们对SNM在相关领域的进一步应用进行了展望和展望。
