The present invention provides a linear nano titanium dioxide / titanium carbide preparing a two-dimensional layered composite material, comprising: a high-energy ball milling high purity Layered Ternary Ti3AlC2 powder grain refinement; two-dimensional layered nanomaterials MXene- Preparation Ti3C2 hydrofluoric acid etching; alkaline hydrothermal treatment MXene-Ti3C2 and P25, the nano TiO2 linear load MXene-Ti3C2, namely linear nano TiO2 / MXene-Ti3C2 nanocomposites; the present invention uses non-toxic materials and simple preparation process, process control, low cost, uniform sheets prepared by the two-dimensional layer of MXene-Ti3C2, TiO2 nanowires slender and evenly distributed, so that the composite material is greater than the surface area, good electrical conductivity, good photocatalytic properties , pro-biotic is good, beneficial applications in the field of photocatalysis, wastewater treatment, lithium-ion batteries and biosensors.

The present invention discloses a steel pickling and pickling process based on Fenton oxidation. The pickling solution in percent by mass, 1 to 5% starting agent, 5 to 30% sulfuric acid, 3 to 10% of hydrofluoric acid, hydrogen peroxide, 0.1 to 20%, from 0.05 to 2.0% corrosion inhibitor, a stabilizer of 0.01 to 2.0% , 0.05 to 1.0 percent wetting agent, 0.01 to 1.0% brightener and water balance. Pickling the present invention has a nitric acid-free pickling speed, good quality, etc., at the same time solve the pickling plant to take tobacco, as well as nitrogen-containing wastewater and other environmental problems. Acid and hydrogen peroxide in a mixture jet manner from the liquid dispensing tube discharge orifice acid, acid cyclone was rolling up and down like this pickling process can be accelerated oxide skin peeling, greatly improve the reaction efficiency, conservation agent usage and operating costs.
