Transformation of CO₂ into value-added products via photothermal catalysis has become an increasingly popular route to help ameliorate the energy and environmental crisis derived from the continuing use of fossil fuels, as it can integrate light into well-established thermocatalysis processes. The question however remains whether negative CO₂ emission could be achieved through photothermal catalytic reactions performed in facilities driven by electricity mainly derived from fossil energy. Herein, we propose universal equations that describe net CO₂ emissions generated from operating thermocatalysis and photothermal reverse waterâ€“gas shift (RWGS) and Sabatier processes for batch and flow reactors. With these reactions as archetype model systems, the factors that will determine the final amount of effluent CO₂ can be determined. The results of this study could provide useful guidelines for the future development of photothermal catalytic systems for CO₂ reduction.

热与光热 CO2 催化的 CO2 足迹

通过光热催化将 CO ₂转化为增值产品已成为一种越来越受欢迎的途径，以帮助缓解因持续使用化石燃料而导致的能源和环境危机，因为它可以将光整合到完善的热催化过程中。然而，问题仍然是是否可以通过在主要来自化石能源的电力驱动的设施中进行光热催化反应来实现负 CO ₂排放。在此，我们提出了描述净 CO _{2 的}通用方程运行热催化和光热逆向水-气体变换 (RWGS) 和间歇和流动反应器的 Sabatier 工艺产生的排放。将这些反应作为原型模型系统，可以确定决定流出物 CO ₂最终量的因素。该研究的结果可为未来开发用于 CO ₂还原的光热催化系统提供有用的指导。
