Photothermal catalysis is an innovative chemical technology that cleverly combines light energy (such as energy from the sun or artificial light sources) with thermal energy to drive chemical reactions. Simply put, it is like having the two keys "light" and "heat" work together to accelerate molecular transformations, making reactions that were originally slow or inefficient become fast, efficient, and controllable. This technology has broad applications in environmental remediation, energy conversion, and materials synthesis—for example, CO₂ reduction, ammonia synthesis, and organic oxidation—helping to reduce carbon emissions and promote sustainable development.
The core advantage of photothermal catalysis lies in its synergistic effect. Light provides high-energy input to excite catalysts (such as semiconductor materials) to generate active species, while heat lowers reaction barriers and accelerates molecular motion, thereby enhancing reaction rates and selectivity. For example, in CO₂ reduction reactions, photothermal synergy can realize multi-field catalysis (light, heat, pressure), allowing reactions to run under a wide range of temperatures (e.g., up to 550°C) and pressures (e.g., 1.6 MPa), broadening the applicable reaction conditions and improving product yield and efficiency. This synergy applies not only to liquid-phase reactions but also extends to gas–solid systems, such as photothermal ammonia synthesis, offering flexibility for industrial applications.
Another key advantage is high efficiency and energy saving. Photothermal catalysis often uses solar-simulating light sources, reducing dependence on external energy while minimizing energy loss through optimized reaction conditions (such as temperature and pressure control). For example, in photothermal CO₂ reduction, systems can automatically adjust parameters to achieve high reaction efficiency and reduce byproduct formation, which is crucial for large-scale environmental applications (such as carbon capture).
Our company's products provide strong support in the field of photothermal catalysis, highlighting its applications and advantages. For example, the PLR MFPR-I multifunctional photochemical reactor supports multi-field synergistic catalysis of light, heat, and pressure, with temperatures up to 180°C and pressures up to 0.9 MPa, and integrates fully automatic online sampling that can be coupled with chromatography to reduce human error and improve experimental efficiency. For gas–solid reactions, the PLR-PTSRⅡ photothermal catalytic reactor reaches parameters up to 550°C and 1.6 MPa, compatible with both flow and sealed operation modes, and is suitable for photothermal CO₂ reduction and ammonia synthesis scenarios, providing a controllable photothermal coupling platform.
In addition, the Labsolar-6A fully glass automated online trace gas analysis system uses high-borosilicate glass material, offering high chemical inertness and low gas resistance; in photothermal catalysis experiments it avoids gas adsorption and faithfully reflects the intrinsic activity of the catalyst, ensuring data accuracy. For product analysis, our isotope-labeling testing services (e.g., using ¹³C or ¹⁸O labeling) can efficiently separate and trace CO₂ reduction products, helping to evaluate the true activity of catalysts and improve research reliability. These products are highly integrated, easy to operate, and can reduce experimental errors, making photothermal catalysis research more efficient and reliable.
In summary, photothermal catalysis, through the synergistic action of light and heat, offers efficient solutions for green chemistry and sustainable development. With our company's advanced instruments and services, researchers can more easily explore this field and drive technological innovation.
