Embodiment 1

[0035] (1) Preparation of Fullerenol (C60(OH) 44 .8H 2 O): Add 0.100g C60 to the beaker, then add 7mL of 1,2,4-trimethylbenzene solution to disperse C60, then add 4.6mL 30% H 2 o 2 , C60 and 30%H 2 o 2 The molar ratio of TBAH is 1:320, and it is completely dissolved after magnetic stirring in an oil bath at 60°C for 30 minutes, then 400 μL of TBAH is added, and magnetic stirring is performed for 16 hours; a light yellow aqueous solution is separated from the resulting solution with a mass ratio of 5 : 4:5 isopropanol: ethyl acetate: n-hexane mixed solution mixed to obtain a milky white precipitate. The precipitate was washed twice with deionized water and twice with methanol, and then dried under vacuum at room temperature for 10 hours.

[0036] (2) Preparation of fullerenol / palladium nanocomposite photocatalyst: add 0.0161g fullererol to a clean beaker, add 50mL water, then add 0.0208gNa 2 PdCl 4 , 5mL methanol was stirred and dissolved, the methanol solution concentra...

Abstract

The invention relates to the field of photocatalysts, and discloses a fullerol / palladium nano-composite photocatalyst as well as a preparation method and application thereof. In the fullerol / palladium nano-composite photocatalyst, the chemical formula of fullerol is C60(OH)44.8 H2O, the average particle size of palladium nano-particles is 3-4 nm, and the palladium nano-particles are used for CO2 photocatalytic reduction. According to the invention, photogenerated electron-hole pair compounding can be effectively delayed and hindered, and a relatively good photocatalytic effect is achieved; the prepared fullerol and palladium nano-composite photocatalyst is uniform in size and good in crystallinity, and has the characteristics of high catalytic efficiency and high catalytic rate; the average particle size of palladium metal particles in the prepared fullerol and palladium nano-composite photocatalyst is 3-4 nm, and the fullerol is easy to capture electrons; and the fullerol and palladium nano-composite photocatalyst is green and environment-friendly and can be recycled.

Description

technical field [0001] The invention relates to the field of photocatalysts, in particular to a fullererol / palladium nanocomposite photocatalyst and a preparation method and application thereof. Background technique [0002] Fullerene is a carbon atom cluster structure molecule C60 composed of 60 carbons. Contains twenty six-membered rings and twelve five-membered rings. Different from the sp2 hybridization of the same plane in graphite, the conjugated π bonds in fullerene are non-planar, so the ring current is small and the aromaticity is poor, showing the nature of unsaturated double bonds. That is, although the carbon atoms in the fullerene molecule are hyperconjugated, the fullerene as a whole is not aromatic. Due to the presence of twelve five-membered rings, fullerenes need an additional 12 electrons to form the most stable closed-shell system. Therefore, fullerenes can easily capture electrons and are excellent hosts for metal atoms. Both the electron-phonon and e...
