The invention relates to a MXene-hydroxy modified titanium carbide ultra-thin nanobelt and a fluorine-free synthesis method thereof. The method includes the following steps that: a Ti3AlC2 precursor and KOH are weighed according to a mass ratio, the Ti3AlC2 precursor and the KOH are fully ground and mixed, so that a mixed material can be obtained; deionized water is added to the mixed material according to a mass ratio, and an obtained mixture is fully ground and mixed, so that a slurry can be obtained; the obtained slurry is transferred into a polytetrafluoroethylene liner, and the polytetrafluoroethylene liner with the slurry is placed in a stainless steel reactor, so as to be subjected to hydrothermal etching, after the etching is completed, precipitates are taken out, ultrasonication and centrifugation are carried out sequentially, a product is collected, the product is washed with water until the pH of the product is 7, and then the product is washed with alcohol; and an obtainedproduct is dried in a con
