Energy crisis and environmental pollution are two major challenges currently facing mankind, and the development of clean low-carbon new energy such as solar energy is imperative. The photocatalysis technology can directly convert solar energy into chemical energy, and the core of the technology is the synthesis of a stable and efficient photocatalyst. Nano titanium dioxide (TiO) 2 ) The material is considered as one of the most potential photocatalysts due to its characteristics of low cost, high efficiency and environmental friendliness. However, such TiO compounds 2 The material also has some non-negligible defects, such as wider energy band gap, faster recombination rate of photogenerated electron-hole pairs, shorter service life of photogenerated carriers and the like, which seriously limit the practical application of the material in the field of photocatalysis.
In recent years, titanium oxide cluster based coordination polymers have become one of the most attractive coordination polymers due to their wide application prospects in photocatalysis and optoelectronics. However, the development of titanium oxide cluster-based coordination polymers is still in the initial stage, and the reason is presumed to be as follows: (1) The high reactivity and easy hydrolysis of the titanium source lead to low crystallinity of the product and even difficult crystallization; (2) The higher charge/radius ratio (Z/r) of Ti (IV) causes the association/dissociation process reversibility of coordination bonds between titanium nodes and ligands to obstruct the formation of a high-crystallinity network structure. In order to make better use of solar energy, development of a novel titanium oxide cluster-based coordination polymer material which is highly efficient and stable has become an important research topic.
