Novel high-efficiency strontium borate-like photocatalyst

Abstract

The invention discloses a high-efficiency strontium borate-like photocatalyst and a preparation method thereof and aims to prepare methane by reducing carbon dioxide and water through photocatalysis technology. In the photocatalyst, strontium salt, a boron-containing compound, citric acid or citrate and alcohols are used as precursors. The photocatalysis efficiency of reducing the carbon dioxide and water to prepare the methane of the high-activity strontium borate-like photocatalyst prepared by a sol-gel method is superior to that of a TiO2 photocatalyst (P25, which is known as the photocatalyst with higher photocatalysis efficiency at present). The novel high-efficiency strontium borate-like photocatalyst has the advantages of simple preparation process, easy operation, low requirements on equipment and the like and has wide application prospect and development potential in the fields of emission reduction of carbon dioxide, recycling of energy, environmental science and the like.
