| 报告介绍 | 报告摘要：
As the evidence of global climate change becomes ubiquitous and the resulting environmental impact is increasingly severe, there is a pressing need to mitigate the negative effects of fossil energy consumption, of which CO2 emission is the major concern. Photocatalytic reduction of CO2 offers a promising solution because it not only reduces the amount of CO2 released to the atmosphere, but also converts the green house gas into useful chemicals and fuels, such as methane, CO, methanol, etc. Despite the great promise of this approach, the artificial photocatalytic CO2 reduction is highly inefficient and impractical. One of the challenges is that metal oxide based photocatalysts are incapable of utilizing visible and near infrared photons for photocatalysis. We have developed various heterostructured catalysts which exploit the attractive optical properties of semiconductor and metal nanocrystals to sensitize wide band-gap metal oxide catalysts. These heterostructured catalysts have shown CO2 reduction activity deep into the red tails of the visible spectral region. Mechanisms of different types of heterostructured catalysts will be discussed. Our most recent effort in developing methods for utilizing plasmon-assisted catalysts for CO2 conversion applications will also be described.
