Photothermal CO₂ Catalysis toward the Synthesis of Solar Fuel: From Material and Reactor Engineering to Techno‐Economic Analysis

Abstract

Carbon dioxide, a member of greenhouse gases, contributes significantly to maintaining a tolerable environment for all living species. However, with the development of modern society and the utilization of fossil fuels, the concentration of atmospheric CO2 has increased to 400 ppm, resulting in a serious greenhouse effect. Thus, converting CO2 into valuable chemicals is highly desired, especially with renewable solar energy, which showed great potential with the manner of photothermal catalysis. In this review, recent advancements in photothermal CO2 conversion are discussed, including the design of catalysts, analysis of mechanisms, engineering of reactors, and the corresponding techno‐economic analysis. A guideline for future investigation and the anthropogenic carbon cycle are provided.This article is protected by copyright. All rights reserved
