Abstract

The invention discloses a preparation method of a two-dimensional nano electrode material which is free of noble metal doping, low in cost, easy to prepare and high in electrooptic activity, and belongs to the technical field of novel nano functional materials and green energy. The method comprises the steps that a copper doped titanium dioxide nanosheet material is composited in situ on a molybdenum disulfide nanosheet of a copper intercalation layer, and the two-dimensional nano composite material Cu-TiO2/MoS2 is obtained by in-situ compositing molybdenum disulfide with copper doped titanium dioxide nano blocks through a one-pot method. The prepared Cu-TiO2/MoS2 can be applied to the fields of solar energy photovoltaic cell preparation, photoelectrochemistry sensor construction, photocatalytic water splitting for hydrogen production, photocatalytic degradation of organic pollutants and the like.
