Description

technical field [0001] The invention relates to the use of a two-dimensional transition metal oxide single-layer nanosheet rich in cation defects in water evaporation and electricity generation, and belongs to the technical field of water evaporation and electricity generation. Background technique [0002] With the continuous development and utilization of primary energy such as oil and natural gas, the energy crisis and global warming continue to threaten human development. Therefore, finding a sustainable green energy production method has become one of the most urgent challenges facing mankind. Among many green energy power generation methods, water evaporation power generation is a power generation method that converts the heat energy of the surrounding environment into electric energy through water evaporation. This method utilizes natural phenomena to generate electricity without external mechanical action and energy input. In order to imitate the phenomenon of water...
