Photocatalytic gas-solid reaction is considered a powerful tool to address environmental pollution and energy crisis, but challenges such as catalyst poisoning, low efficiency, and uncontrollable selectivity remain unresolved. Revealing and elucidating the reaction mechanisms is crucial to overcome these challenges. This article discusses and summarizes five major types of gas-solid photocatalytic reactions, providing insights into key reaction steps and proposing prospective viewpoints for future development.
The photocatalytic gas-solid reaction has been regarded as a powerful tool to solve the environmental pollution and energy crisis. However, problems such as catalyst poisoning, low reaction efficiency, and uncontrollable selectivity are still unsolved, which largely restrict the development of photocatalysis. Therefore, it is significant to reveal and elucidate the reaction mechanisms of gas-solid photocatalysis. Herein, the five major types of gas-solid photocatalytic reactions including the oxidation of NOx, volatile organic compounds (VOCs) and NH3, and reduction of CO2 and N-2 are discussed and summarized. For each system, the composition and basic properties of gas molecules, the process of adsorption and activation, and various reaction pathways are discussed. Finally, some prospective viewpoints for the future development of gas-solid photocatalysis are proposed.
