Embodiment 1

[0022] A simple and efficient preparation of flexible paper-based platinum nanoparticles-multi-branched titanium dioxide nanotube composites, the specific preparation process is as follows:

[0023] (1) Select chromatographic paper as the paper base, and use a paper cutter to cut the chromatographic paper into A4 size;

[0024] (2) Use AI CS4 software to design the hydrophobic wax printing pattern of the paper substrate on the computer;

[0025] (3) Use a wax printer to print the hydrophobic wax printing pattern designed in step (2) on A4 paper, then take out the A4 paper, place it in an oven, and heat it at 130 ºC for 2 min to melt the wax and soak the entire paper thickness, forming a hydrophobic wall, that is, a rectangular black area on A4 paper, and the part without wax printing is a hydrophilic area, that is, a white area similar to a light bulb shape on A4 paper;

[0026] (4) Use a paper cutter to cut the A4 paper obtained in step (3) into multiple independent paper pi...

Description

technical field [0001] The invention relates to a preparation method of a flexible paper-based platinum nanoparticle-multi-branch titanium dioxide nanotube composite, belonging to the field of preparation of inorganic semiconductor nanomaterials. Background technique [0002] Titanium dioxide is a common semiconductor material, including three crystal structures of anatase, rutile and brookite. Because of its high photocorrosion resistance, chemical stability, non-toxicity and low price, it is widely used in various optoelectronic devices and optoelectronic biosensing fields. [0003] One-dimensional titania nanomaterials, including titania nanorods and titania nanotubes, exhibit faster photoelectron transfer rate and higher charge separation efficiency than titania nanoparticles and bulk titania, thus becoming a hot research material for current researchers , especially in the field of biosensing, is often used as a biosensing substrate to load other types of biomolecules....
