The linear structure of PtNWs is not easy to dissolve and lose compared with Pt particles, and the linear structure is more conducive to the transfer of materials and electrons at the reaction interface, so it can show better performance and life.
Due to its unique size and structure, nanomaterials have different characteristics from general materials: volume effect, surface effect, quantum size, quantum tunnel and dielectric confinement.
Nowadays, the highly developed nanotechnology has made nano materials widely used in traditional materials, medical equipment, electronic equipment, coatings and other industries [3].

Quartz belongs to the hard and brittle materials, which has the characteristics of high strength, not conductive, low fracture toughness and high hardness [1].
Considering the chemical etching processing principle of the quartz materials and the existing processing technology, HF, HF+CH3COOH, NH4HF2 and NH4F+HF dissolved solution are currently used.
