Abstract

The invention relates to a photo-electrochemical cell with a nanostructure for solar hydrogen production and preparation thereof, and belongs to the field of utilization of a new energy resource. A photo-electrode with the nanostructure is a nanorod array with zinc oxide deposited on one side of a conductive substrate. The method comprises the following steps of: growing a thin zinc oxide seed layer on the conductive substrate by chemical thermal decomposition; reversely placing the substrate in reaction solution to prepare the zinc oxide nanorod array photo-electrode with controllable size by using a liquid-phase chemical deposition method; and finally assembling the photo-electrode into the photo-electrochemical cell. The zinc oxide nanorod array photo-electrochemical cell has superior performance and readily available chemical raw materials, and avoids a high-temperature annealing process so as to save the cost compared with a conventional method. The method has the advantages of simple technological process, easy control, simple preparation and test equipment, easy mass production and the like.

Description

Technical field [0001] The invention relates to a nanostructured photoelectrochemical cell used for solar hydrogen production and a preparation method thereof, belonging to the field of clean and renewable new energy utilization. Background technique [0002] The biggest challenge for the development of human society today is the energy crisis and environmental pollution. After two industrial revolutions in the 19th and 20th centuries, mankind entered an advanced industry and a highly civilized modern society. However, the rapid development of industrial society has also led to a large consumption of energy. It is estimated that the energy system the world relies on today, that is, fossil energy (including coal, oil, and natural gas) can only last for less than a hundred years. Moreover, with the continuous scarcity of energy sources, the difficulty and cost of mining new energy sources have also increased greatly, and the energy consumed may even approach or exceed the energy ...
