“…Furthermore, nano-Ag has synergistic anti-mold effects with TiO 2 due to its own anti-mold abilities [17]. However, after doping with Ag, the enhanced polarity of TiO 2 makes it easier to agglomerate [18][19][20].…”

Ag/TiO2 wood-based nanocomposites were prepared by the methods of ultrasound impregnation and vacuum impregnation. The as-prepared samples were characterized by field emission scanning electron microscopy (FESEM), energy-dispersive spectroscopy (EDS), Fourier transform infrared spectroscopy (FTIR), mercury intrusion porosimetry (MIP), and water contact angles (WCAs). The anti-mold properties of the Ag/TiO2 wood-based nanocomposites were improved by 14 times compared to those of the original wood. The nano-Ag/TiO2, which was impregnated in the tracheid and attached to the cell walls, was able to form a two-stage rough structure and reduce the number of hydroxyl functional groups on the wood surfaces. The resulting decline of wood hydrophobic and equilibrium moisture content (EMC) destroyed the moisture environment necessary for mold survival. Ag/TiO2 was deposited in the wood pores, which reduced the number and volume of pores and blocked the path of mold infection. Thus, the anti-mold properties of the Ag/TiO2 wood-based nanocomposite were improved by cutting off the water source and blocking the mold infection path. This study reveals the anti-mold mechanism of Ag/TiO2 wood-based nanocomposites and provides a feasible pathway for wood-based nanocomposites with anti-mold functions.

“…For example, the highly contacted geometry of nanocomposite material could promote charge spatial separation by forming heterojunctions for effective charge collection and suppressed charge recombination, contributing to the subsequent surface chemical reactions. Moreover, many cases have shown that the exterior material with high chemical stability can passivate and protect the delicate core component, thereby benefiting the long‐term stability . Such idea was recently adopted to solve the stability issues of the halide perovskite nanocrystals by embedding them into silica, aluminum oxide, or polymer matrixes.…”

photocatalysis, including traditional alternatives such as metal oxides (e.g., TiO 2 , perovskite oxides), [3][4][5][6][7][8][9] metal sulfides, [10][11][12] C 3 N 4 , [13,14] carbons, [15,16] metal organic frameworks. [17][18][19][20] Morover, our group for the first time has reported that the CsPbBr 3 quantum dot, a representative lead halide perovskite material, was able to conduct the photocatalytic reduction of CO 2 . [21] By virture of the high extinction coefficient, broad light absorption range, and long electron-hole diffusion length, [22][23][24][25][26] currently the lead halide perovskite materials have gained impressive momentum in photocatalytic researches including HI splitting, [27,28] CO 2 reduction, [21,29,30] and selective oxidation of alcohols. [31] Nevertheless, the overall efficiencies are still far from satisfaction and hanker for rational material designs.As an alluring concept, encapsulation strategy was regarded as a promising technology for high-performance optoelectronic or photochemical applications because of several advantages. For example, the highly contacted geometry of nanocomposite material could promote charge spatial separation by forming heterojunctions for effective charge collection and suppressed charge recombination, [32] contributing to the subsequent surface chemical reactions. Moreover, many cases have shown that the exterior material with high chemical stability can passivate and protect the delicate core component, thereby benefiting the long-term stability. [33][34][35][36][37] Such idea was recently adopted to solve the stability issues of the halide perovskite nanocrystals by embedding them into silica, [38,39] aluminum oxide, [40,41] or polymer [42][43][44][45] matrixes. However, accompanied by the greatly enhanced stability, the electric interaction between the nanocrystals and outer media was also interdicted due to the insulating encapsulation material, which was unsuitable for the photocatalytic applications. Especially, among numerous matrix material candidates, amorphous TiO 2 (a-TiO 2 ) has been proved a valid one for improving the photocatalytic or photoelectrochemical performances of the pristine counterparts. Although the amorphous TiO 2 itself has relatively poor photocatalytic response, its chemical stability makes it a good candidate as protection layer to prevent the corrosion or back reactions. [35,46,47] Moreover, since the amorphous TiO 2 possesses moderated conductivity and can build band energy offset Artificially photocatalytic reduction of CO 2 into valuable chemicals, responding to the call of carbon neutral economy, has aroused considerable interests so far. Among those photocatalysts screened, an emerging and promising alternative of inorganic CsPbBr 3 perovskite has recently been reported. Here, to attain preferable photocatalytic performance, an amorphous-TiO 2 -encapsulated CsPbBr 3 nanocrystal (CsPbBr 3 NC/a-TiO 2 ) hybrid is demonstrated through a solution processing strategy. After optimizing the a-TiO 2 matrix amount by tuning the ...

“…Greater stability was also found for Al 2 O 3 -coated Ag nanowire films ( Figure 8 ), where a 5.3 nm thick Al 2 O 3 layer increased the stability to 380 °C [ 5 ]. TiO 2 is another material that can be ALD coated on Ag nanowires to enhance the thermal stability [ 72 ].…”

Transparent electrodes (TEs) made of metallic nanowires, such as Ag, Au, Cu, and Ni, are attracting increasing attention for several reasons: (1) they can act as a substitute for tin oxide-based TEs such as indium-tin oxide (ITO) and fluorine-doped tin oxide (FTO); (2) various methods exist for fabricating such TEs such as filtration, spraying, and Meyer bar coating; (3) greater compatibility with different substrates can be achieved due to the variety of fabrication methods; and (4) extra functions in addition to serving as electrodes, such as catalytic abilities, can be obtained due to the metals of which the TEs are composed. There are a large number of applications for TEs, ranging from electronics and sensors to biomedical devices. This short review is a summary of recent progress, mainly over the past five years, on silver nanowire-based TEs. The focus of the review is on theory development, mechanical, chemical, and thermal stability as well as optical properties. The many applications of TEs are outside the scope of this review.
