Description

Technical Field

[0001] The invention relates to the field of instruments for testing catalyst reaction performance, and more specifically to a constant temperature furnace for photothermal synergistic reaction. Background Art

[0002] Photothermal synergistic reaction combines light and heat. At a certain reaction temperature, with the assistance of light, the reaction performance of the catalyst is generally much higher than the single photocatalytic and thermal catalytic activity. Therefore, to achieve the same reaction activity, the reaction temperature can be significantly reduced with the participation of light, and the selectivity of the reaction can be improved. Conversely, the presence of a heat source can reduce the energy of the required light source, that is, at a certain temperature, the reaction that originally required a very high energy light source can be completed under conventional white light (390-780nm) and ultraviolet light source (254nm). Therefore, the photothermal synergistic reactor gives full play to the synergistic effect of light and heat, so that the photothermal effect promotes each other, and its application is becoming more and more extensive.

[0003] The internal furnace of a conventional reactor is a solid structure, which is not suitable for introducing light. In actual use, it cannot achieve photothermal synergistic reaction. Its structure has become a problem that restricts the development of photothermal synergistic reaction.
