[Abstract]:The conversion of carbon dioxide to hydrocarbon fuel by artificial light synthesis technology is an ideal technology for chemical conversion and utilization of solar energy, which has attracted more and more attention from scientific and industrial circles in recent years. The construction and application of high efficiency synthetic materials based on wide spectral response of semiconductors and nanometallic materials in recent years are reviewed from the following three technical approaches: (1) starting from the thermodynamic conditions of artificial light synthesis, Based on the semiconductor energy band engineering design, a new type of high efficiency synthetic materials was prepared. (2) based on the surface plasmon resonance effect of nanometer precious metals, the wide spectrum response artificial light synthesis system based on nanometer metals was designed and fabricated. It can effectively expand the optical absorption range to near infrared region. (3) by using the photothermal effect of 鈪，
