“…In order to improve indoor air quality, many strategies are developed to remove HCHO from indoor air, including adsorption, [7][8][9] ozone oxidation techniques, [10,11] photocatalytic oxidation, [12,13] plasma techniques, [14,15] thermal or low-temperature catalytic oxidation. [16,17] Among them, conventional adsorption techniques can only temporarily immobilize HCHO molecules on the surface of porous materials, but the adsorption capacity of HCHO on these materials is low, and the desorption of HCHO may even result in secondary pollution.…”

Formaldehyde (HCHO) is one of major pollutants in indoor air, and prolonged exposure to HCHO may result in great harm to human health. Therefore, it is crucial to remove HCHO from indoor air at room temperature. In recent years, various room temperature catalysts, which have the advantages of environmental friendliness and energy saving, were developed for high effective catalytic oxidation of HCHO. In this work, research progress and challenges on the room temperature catalytic oxidation of HCHO by using noble metal catalysts and non‐noble metal catalysts are systemically reviewed. Meanwhile, the room temperature catalytic oxidation performance, degradation conditions of HCHO, and room temperature catalytic oxidation mechanism of catalysts was also discussed.

“…Further, organic dye wastewater is one of the pollutants that have always existed in the printing and dyeing industry. Currently, the common treatment methods for formaldehyde and organic wastewater include adsorption [ 2 , 3 ], oxidation [ 4 , 5 ], biological treatment [ 6 , 7 ], and photocatalytic method [ 8 , 9 ], etc. As one of the best functional materials, TiO 2 is also widely used for surface property improvement of wood due to its excellent chemical stability and non-toxicity.…”

In this paper, a surface self-cleaning wood was obtained by loading Bi2O3-doped silica–titanium composite film on the surface of wood by the sol–gel method. The effects of different Bi doping amounts on the structure and photocatalytic properties of the modified wood were investigated. The doping of Bi2O3 inhibited the growth of TiO2 crystals and the phase transition from anatase to rutile. In addition, Bi2O3 could improve the photocatalytic activity of the composite film by appropriately reducing the grain size of TiO2 and increasing the crystallinity of TiO2. Furthermore, doping with Bi2O3 shifted the absorption wavelength of the wood samples back into the visible range, indicating that the increase in Bi content favoured light absorption. The wood samples loaded with Bi2O3-doped Si–Ti composite membranes had the best photocatalytic activity and the highest reaction rate when n (Ti):n (Bi) = 1:0.015. Degradation rates of 96.0% and 94.0% could be achieved for rhodamine B and gaseous formaldehyde, respectively. It can be seen that wood samples loaded with Bi2O3-doped Si–Ti composite films on the surface exhibit excellent photocatalytic activity against both gaseous and liquid pollutants.
