Constant-temperature furnace for photo-thermal synergistic reaction

Abstract

The invention discloses a constant-temperature furnace for a photo-thermal synergistic reaction. The constant-temperature furnace comprises an inner furnace body, a heating body, an outer shell and alight-transmitting assembly, the inner furnace body is of a closed structure with a hearth, and at least one inner light-transmitting hole is formed in the side wall of the inner furnace body. The heating bodies are uniformly fixed on the inner surface of the inner furnace body and are used for heating the hearth; the outer shell wraps the outer side of the inner furnace body in a sealed mode, andouter light-transmitting holes corresponding to the inner light-transmitting holes are formed in the side wall of the outer shell. The light-transmitting assembly is detachably connected to the edgeof the outer side of the outer light-transmitting hole in a sealed mode and used for transmitting light and filtering light of a light source irradiating into the hearth. According to the constant-temperature furnace with the light holes, the light source is located on the outer side of the constant-temperature furnace, the light source is introduced from outside to inside through the light holes,the light source can be introduced into the hearth, and therefore a photo-thermal synergistic reaction can be achieved; the light-transmitting assembly covers the light-transmitting hole to prevent heat from flowing to the outside, so that the constant-temperature furnace has good heating uniformity, simple structure and good use effect.

Description

technical field [0001] The invention relates to the field of instruments for testing the reaction performance of catalysts, in particular to a constant temperature furnace for photothermal synergistic reaction. Background technique [0002] The photothermal synergistic reaction is the combination of light and heat. At a certain reaction temperature, under the assisted action of light, the reaction performance of the catalyst is generally much higher than that of a single photocatalytic and thermal catalytic activity. Therefore, to achieve the same reactivity, the temperature of the reaction can be significantly reduced and the selectivity of the reaction can be improved under the participation of light. Conversely, the existence of the heat source can reduce the energy of the required light source, that is, at a certain temperature, the reaction that originally requires a very high-energy light source can be performed in the conventional white light (390-780nm) and ultraviol...
