Abstract: Provided are a nano-titanium dioxide (NT)/biochar (BC) composite, and a preparation method and use thereof, which belong to the technical field of cement-based materials. NT is introduced into a porous structure of the micron-sized BC, which not only addresses the high aggregation of NT, but also reduces Ca(OH)2 size and crystal growth orientation through effects such as filling and nucleation brought by NT in the porous structure of BC. In this way, more C—S—H gels are generated to fill the pores, thereby improving an interfacial transition zone (ITZ), which enhances the mechanical properties such as compressive strength and flexural strength. The NT/BC composite of the disclosure is doped into a cement-based material, which allows that in a surface layer of the cement-based material, CO2 absorption capacity could be improved through carbon sequestration properties and the porous structure of the composite, and the carbonization of the surface layer could be accelerated by hydration accelerating properties of the NT to form a calcium carbonate surface protective layer, thereby improving durability of the cement-based material.
