Abstract

The invention provides a construction method of a curved surface honeycomb array and application of the curved surface honeycomb array, and particularly relates to evolution of two different curved surface honeycomb structures and feasible application in different fields. A solution used for light-operated growth regulation is selected from one of a silver nitrate solution, a tetraammineplatinum dihydroxide solution and a chloroauric acid solution. According to the construction method of the curved surface honeycomb array and application of the curved surface honeycomb array, the structure is further evolved on the basis of the prior art, the operability of the structure is further improved, meanwhile, the production period of an ordered nanostructure active substrate is not long, the cost is low, the test condition requirements are relatively simple, therefore, the construction method of the curved surface honeycomb array and application of the curved surface honeycomb array have the advantages that the uniformity is good, the order degree is high, the repeatability is high, construction steps are simple, the production period is short, and the cost is low, and the operable space of the nanometer ordered structure and the applicable space of the substrate are further enlarged.
