It discloses a vanadium-titanium compound material with high thermal stability and high activity and a preparation method thereof. The vanadium-titanium compound material is mainly composed of vanadium oxide and titanium oxide, where the content of vanadium oxide is 0.5% to 30% by mass of the vanadium-titanium compound material, and the crystal form of titanium oxide in the vanadium-titanium compound material is one of anatase and TiO(B) or a mixture thereof.

Vanadium-titanium compound material with high thermal stability and high activity and preparation method thereof

A method for regenerating a Cu-BTC material includes: impregnating a Cu-BTC adsorbed with guest molecules in an acidic proton solvent or in a steam environment thereof, and filtering the Cu-BTC material, to obtain a solid; impregnating the solid in a non-acidic organic solvent or a steam environment thereof, and finally filtering, washing and drying the solid, to complete the generation of the Cu-BTC material.

Regeneration method for Cu-BTC material

A preparation method of carbon modified filler is provided. The method is: putting the fillers into the reaction zone of a reactor, starting the first heating-up to 400-500&#xb0; C. under the protective atmosphere at first, then introducing hydrogen after the heating-up; starting the second heating-up to 600-1200&#xb0; C. after introducing hydrogen and simultaneously introducing the mixture of hydrogen and carbon source gas, keeping at the terminal temperature for 0.1-5 hours, introducing nitrogen and stopping heating after the reaction, cooling, and then getting the carbon modified filler. The above method can obtain a friction material with good mechanical properties, excellent friction and wear performances, stable friction coefficient at high temperature, good braking force and no heat recession.

Preparation method of carbon modified filler

The methods for preparing Cu-BTC and nano-Cu-BTC are disclosed. An imporous coordination compound Cu(CHO)(HO)is impregnated an organic solvent or a steam environment thereof to obtain Cu-BTC. Cu-BTC is impregnated in an acidic protic solvent environment and filtered to obtain a solid, and the solid is impregnated in a non-acidic organic solvent or a steam environment thereof, centrifuged, washed, and dried, to obtain nano-Cu-BTC.
