Potassium Titanate: An Alternative Support for Gold Catalyzed Carbon Monoxide Oxidation?

Crystalline Structure, Synthesis, Properties and Applications of Potassium Hexatitanate: A Review

Potassium hexatitanate (PHT) with chemical formula K₂Ti₆O₁₃ has a tunnel structure formed by TiO₂ octahedra sharing edges or corners and with the potassium atoms located in the tunnels. This material has attracted great interest in the areas of photocatalysis, reinforcement of materials, biomaterials, etc. This work summarizes a large number of studies about methods to prepare PHT since particle size can be modified from millimeter to nanometric scale according to the applied method. Likewise, the synthesis method has influenced the material properties as band-gap and the final mechanical performance of composites when the reinforcement is PHT. The knowing of synthesis, properties and applications of PHT is worthwhile for the design of new materials and for the development of new applications taking advantage of their inherent properties.
