Titanium dioxide and prussian blue orderly assembled mesocrystal nano material and preparation method thereof

Abstract

The invention discloses a preparation method of a titanium dioxide and prussian blue ordered assembly state mesocrystal nano material. The preparation method comprises the following steps: preparing anovel flower-like mesocrystal nano material consisting of nanowire arrays by utilizing a hydrothermal method; preparing the monodisperse high-purity flower-like titanium dioxide and prussian blue composite material (TiO2-PB) by taking potassium ferrocyanide and titanium sulfate as raw materials, PVP as a stabilizer and diluted hydrochloric acid as a solvent and reacting at a specific temperature.The preparation method is simple in preparation process, reliable in design principle, low in production cost, short in period and environment-friendly in application; the prepared composite materialis good in monodispersity, high in purity and uniform in morphology, and has a wide application prospect in various aspects. A solid film constructed by utilizing the composite material can be conveniently applied to the surface of conventional paper so as to produce inkless printing rewritable paper with the same hand feeling and appearance. The composite material and the solid film are simple and convenient to produce, and the light printing mode is simple, environment-friendly, safe and efficient.

Description

Technical field[0001]The invention belongs to the technical field of materials, and specifically relates to a one-step synthesis of titanium dioxide and Prussian blue ordered assembled mesogenic nanomaterials and a preparation method thereof.Background technique[0002]Metal organic frameworks (MOF) and inorganic nanocrystals (INC) are both powerful materials that help alleviate the energy crisis and solve environmental problems. Some examples of successfully assembling the complementary functions of MOF and INCS provide a good reference for the design of new materials, for example, the TiO grown in the hole of MIL-1012 NCs has produced a new type of catalyst that uses TiO2And MOF to promote the photocatalytic reduction of CO2, While generating O2.[0003]However, the self-assembly of MOF-INC with definite crystallographic orientation has not been completed yet. MOF and INCs have different lattice parameters and synthesis methods. Because the self-assembly solution of colloidal particle...
