Titanates are salts of polytitanic acid that can be synthesized as nanostructures in a great variety concerning crystallinity, morphology, size, metal content and surface chemistry. Titanate nanotubes (open-ended hollow cylinders measuring up to 200 nm in length and 15 nm in outer diameter) and nanowires (solid, elongated rectangular blocks with length up to 1500 nm and 30–60 nm diameter) are the most widespread representatives of the titanate nanomaterial family. This review covers the properties and applications of these two materials from the surface science point of view. Dielectric, vibrational, electron and X-ray spectroscopic results are comprehensively discussed first, then surface modification methods including covalent functionalization, ion exchange and metal loading are covered. The versatile surface chemistry of one-dimensional titanates renders them excellent candidates for heterogeneous catalytic, photocatalytic, photovoltaic and energy storage applications, therefore, these fields are also reviewed.

钛酸盐是聚钛酸的盐，其可以合成为纳米结构，涉及结晶度，形态，尺寸，金属含量和表面化学。钛酸盐纳米管（长度不超过200 nm，外径不超过15 nm的开放式空心圆柱）和纳米线（长度不超过1500 nm且直径不超过30-60 nm的实心，细长矩形块）是该领域最广泛的代表。钛酸酯纳米材料家族。这篇综述从表面科学的角度介绍了这两种材料的性质和应用。首先对介电，振动，电子和X射线光谱结果进行了全面讨论，然后介绍了包括共价官能化，离子交换和金属负载在内的表面改性方法。
