The invention provides a preparing method of a limited-range catalyst modified through atomic layer deposition and application.The atomic layer deposition technology is utilized, an ultra-thin oxide layer, Pt nanometer particles and a thick oxide layer are deposited on a carbon nanometer fiber template successively, then calcination is carried out in air to remove the carbon nanometer fiber template, and a Pt-based catalyst with oxide ultra-thin modification and the limited range within an oxide nanometer tube is obtained.The prepared catalyst greatly overcomes the defect that the site of a traditional catalyst metal-oxide interface is limited; compared with a limited-range Pt catalyst without ultra-thin modification and a Pt catalyst with the unlimited range, the limited-range Pt catalyst with ultra-thin modification has the best reduction hydrogenation activity to tetranitro-phenol, and the method can be popularized in preparation of other multi-phase catalysts.
