Abstract

A synergistic combination of photocatalysis and thermocatalysis (photothermocatalysis) has been realized to harness the full solar spectrum with a particular focus on the infrared region to support sustainable oxidation reactions of carcinogenic oxygenated volatile organic compounds such as formaldehyde (FA). Here, recent advances in the oxidative removal of FA in air have been reviewed systematically. First, the fundamentals of the photothermocatalytic mechanism are introduced and discussed. Second, various aspects of the development and application of photothermocatalytic systems are described and reviewed. A specific focus is placed on the physicochemical characteristics of photothermocatalysts with respect to reaction conditions and oxidation performance using FA as a model compound. Third, the pathways and mechanisms of FA oxidation are elaborated and discussed in detail to provide insights into associated surface phenomena and surface chemistry at the molecular level. Finally, current shortcomings and future research directions are identified and discussed to help expand this research field further into the practical realm.

期刊介绍： "Advances in Colloid and Interface Science" is an international journal that focuses on experimental and theoretical developments in interfacial and colloidal phenomena. The journal covers a wide range of disciplines including biology, chemistry, physics, and technology. The journal accepts review articles on any topic within the scope of colloid and interface science. These articles should provide an in-depth analysis of the subject matter, offering a critical review of the current state of the field. The author's informed opinion on the topic should also be included. The manuscript should compare and contrast ideas found in the reviewed literature and address the limitations of these ideas. Typically, the articles published in this journal are written by recognized experts in the field.
