The self-cleaning surface has gained much attention in the field of photocatalytic degradation of NO due to its resistance to dirt pickup and self-cleaning effect in the presence of rainwater. This review analyzes the factors affecting NO degradation efficiency in terms of photocatalyst characteristics and environmental conditions, and discusses the feasibility of photocatalytic degradation of NO on superhydrophilic, superhydrophobic, and superamphiphobic surfaces. The review highlights the importance of self-cleaning surface characteristics on the photocatalytic degradation of NO and evaluates and summarizes the long-term effect using three self-cleaning surfaces. Furthermore, the conclusion and future prospects related to self-cleaning surfaces for photocatalytic degradation of NO are proposed.
Self-cleaning surface has attracted much attention in the field of photocatalytic degradation of NO due to its dirt pickup resistance and self-cleaning effect under the action of rainwater. In this review, the factors affecting NO degradation efficiency were analyzed in terms of photocatalyst characteristics and environmental conditions combined with the photocatalytic degradation mechanism. The feasibility of photocatalytic degradation of NO on superhydrophilic, superhydrophobic and superamphiphobic surfaces was discussed. Furthermore, the effect of special surface characteristics of self-cleaning on photocatalytic NO was highlighted and the improvement of the long-term effect using three self-cleaning surfaces on photocatalytic NO was evaluated and summarized. Finally, the conclusion and outlook were proposed related to the self-cleaning surface for photocatalytic degradation of NO. In future research, the comprehensive effects of the characteristics of photocatalytic materials, self-cleaning characteristics and environmental factors on the photocatalytic degradation of NO and the actual application effects of such self-cleaning photocatalytic surfaces should be further clarified in combination with the engineering. It is believed that this review can provide some theoretical basis and support for the development of selfcleaning surfaces in the field of photocatalytic degradation of NO.
