Photocatalytic Conversion of CO2 into Methane under Solar Irradiation |
| 초록 |
Carbon dioxide is a greenhouse gas of growing concern, and its atmospheric concentration continues to rise from the ongoing burning of fossil fuels. Catalysts that use sunlight to convert CO2 into hydrocarbon fuels are attractive to help mitigate this problem. Here, we describe a multi-template strategy for synthesizing hollow nanocubes of CuO-TiO2-xNx, a new hybrid material that photocatalytically converts CO2 into methane under solar irradiation. The synthetic strategy uses uniform Cu3N nanocubes as both a morphological and compositional template for subsequent deposition of a partial TiO2 shell, oxidation of the Cu3N core to form hollow CuO nanocubes, and low-temperature (450 °C) incorporation of the expelled nitrogen into the TiO2 framework to form crystalline TiO2-xNx. The catalytic performance of the CuO-TiO2-xNx hollow nanocubes (41.3 ppm g-1h-1 of methane) is comparable to other reported photocatalysts that convert CO2 into methane using solar irradiation and without using noble metal co-catalysts. |
