Preparation method of interface Pt-O bonded Pt-Ov-BiOBr catalyst for photocatalytic selective oxidation of 5-hydroxymethylfurfural

The invention discloses a preparation method of an interface Pt-O bonded Pt-Ov-BiOBr catalyst for photocatalytic selective oxidation of 5-hydroxymethylfurfural (5-HMF). The invention further discloses a preparation method of the interface Pt-O bonded Pt-Ov-BiOBr catalyst for photocatalytic selective oxidation of 5-HMF. According to the invention, a mechanism of efficient reaction of superoxide radicals and HMF on a noble metal semiconductor catalysis interface is established, and due to an unsaturated coordination environment on Ov-BiOBr, Pt can form a Pt-O bond to serve as an electron transmission channel, and photo-induced electrons are transmitted to Pt from Ov-BiOBr to efficiently generate superoxide radicals. Meanwhile, photo-generated holes can be gathered on a contact interface of Pt and Ov-BiOBr, and HMF is oxidized to form carbon center free radicals. Superoxide free radicals and carbon center free radicals formed on a Pt-Ov-BiOBr contact interface are relatively close in space, so that mutual collis
