The invention discloses a class P 2 o 5 Structural materials and methods for their preparation and use, the class P 2 o 5 The preparation method of the structural material is as follows: using guanidine phosphate and polyvinylpyrrolidone as precursors, the gas generated by pyrolysis of polyvinylpyrrolidone reacts with guanidine phosphate at high temperature to obtain the P-like 2 o 5 Structural materials. Class P prepared by the present invention 2 o 5 Structural material, as a new nitrogen-phosphorus (NP) material, was first used in the electrochemical selective oxygen reduction industry to produce hydrogen peroxide, and it was found that it has a good The selectivity and yield are beneficial to the application of further industrialized electrocatalytic production of hydrogen peroxide.

The invention relates to the preparation and application of a guanidine-based immobilized affinity magnetic sphere with a core-shell structure, which adopts superparamagnetic iron tetroxide microspheres as a substrate, and 3-(trimethoxysilyl)methanol is bonded on the surface Vinyl-modified magnetic spheres were formed from acrylate-based acrylates, and polymer-coated magnetic spheres with a core-shell structure were obtained by distillation-precipitation polymerization; guanidinium-immobilized core-shell structures were obtained by functional modification of the polymer layer. Polymer coated magnetic balls. In the preparation material of the present invention, utilizing the strong interaction between the guanidinium group and the phosphate group, the polyphosphopeptides in the α-casein (α-casein) or β-casein (α-casein) enzymolysis solution can be respectively realized Or the selective enrichment of all phosphopeptides, the enrichment capacity for phosphopeptides reaches 200 mg / g, the detection limit for phosphopeptides reaches 0.5 fmol, and the recovery rate for phosphopeptides enrichment reaches 91.30%. Utilizing the superparamagnetism of the material, rapid and complete separation can be achieved within 30s.

The invention relates to a guanidine phosphate ultraviolet frequency doubling crystal material and its preparation and application. The chemical formula of the guanidine phosphate material is [C(NH 2 ) 3 ] 6 (PO 4 ) 2 ·3H 2 O belongs to the monoclinic crystal system, its space group is Cc, and the unit cell parameters of the guanidine phosphate material are β=91.90~92.20°, α=γ=90°, Z=4. Compared with the existing materials, the guanidine phosphate material of the present invention has a greater frequency doubling effect, and the frequency doubling intensity of the powder is about KH under 1064nm laser irradiation 2 PO 4 3.8 times that of (KDP) crystals; under 532nm laser irradiation, the powder frequency doubling effect intensity is about β‑BaB 2 o 4 0.3 times of the crystal. In addition, the ultraviolet absorption cut-off edge of this material is at 205nm, which has broad application prospects in the fields of laser frequency conversion, photoelectric modulation, and laser signal holographic storage.
