ABSTRACT
An effective approach utilising catalysts enables the elimination of volatile organic compounds (VOCs), thereby enhancing indoor air quality. The photocatalytic or thermal removal of VOCs regarding multiple nanomaterials is meticulously summated and reviewed in this chapter. The performances, synthesis methods and morphologies of the metallic oxides and carbon-based materials—which form the two principal categories of the materials under investigation—are explicated comprehensively. VOC-reduction paints, construction materials, coatings and air filters are among the emergent building applications for catalytic nanomaterials that serve to enhance outdoor and indoor air quality. The application market of VOC-removal catalysts in buildings is led by metallic oxides such as ZnO and TiO2, which are prevalently featured in the literature, as a result of their high chemical stability, non-toxicity and low cost. Possible candidates for implementation in effective and safe buildings of the future are represented by the distinct catalysts that demonstrated stellar performances and reviewed in the literature. The literature on generating improved outdoor and indoor environment well-being in increasingly healthy buildings will be expanded in this study while also proposing further possible implementations of VOC-reducing catalysts that show strong potential.
