“…In comparison with extensively used ECD materials such as poly/oligothiophene, triphenylamine, viologen, Prussian blue, [44][45][46][47][48][49][50][51] compounds b, c, d, and f displayed slightly better stability, comparable or slightly higher color efficiency, slightly shorter response time, and slightly higher optical contrast (Table 2). This makes them very good candidates for applications such as electronic paper, smart windows, optical memory devices, fullcolor EC display devices, and dual-stimuli-responsive systems.…”

“…The NPB film exhibited a high optical modulation and slight charge density decay after 2000 cycles. Seelandt et al [24] used a TiO 2 thin film possessing an ordered array of mesopores to support PB. The PB/TiO 2 hybrid film had high optical modulation (ΔT = 65%) and fast switching speed (T c = 3 s, T b = 2 s) after 400 cycles.…”

In this study, we examined the cyclic stability of Prussian blue (PB) films in electrolytes with acid. The cyclic stabilities of the PB films were investigated in K+ based electrolytes with different values of solution pH. The acidified KCl solution can significantly improve the durability of the film. Among the three pH values tested, the KCl solutions (pH = 2.15 and pH = 3.03) showed better performance. Furthermore, we investigated the cyclic stabilities of the PB films in LiClO4/PC electrolyte containing different acids. We found that the cyclic stability of PB film was significantly improved when a small amount of acetic acid was dissolved in LiClO4/PC electrolyte. The PB film exhibited stable optical modulation after up to 20,000 cycles in LiClO4/PC electrolyte containing acetic acid—a much higher result than those of some literatures. This suggests that the addition of acetic acid to LiClO4/PC electrolyte can promote the development of PB-based devices with improved stability.

“…The effectiveness of this catalyst was increased by impregnation on mesoporous silica, SBA-15 [19]. Mesoporous silica materials like SBA-15 and MCM-41 have been widely used as support due to high surface area 600-1200 m 2 /g and tunable pore size 2-50 nm [20][21][22].…”

A series of sulfonated Zr-MCM-41 samples were synthesized by the in-situ method followed by sulfonation using sulfuric acid for the catalytic study of cellulose to 5-hydroxymethyl furfural in batch condition. All synthesized catalysts were characterized by XRD, N 2 adsorption-desorption isotherm, FT-IR, TEM, EDX, and NH 3 temperature-programmed desorption analysis. The XRD and N 2 adsorption-desorption isotherm results have confirmed that incorporated Zr 4+ was substituted within the framework of silica MCM-41 with hexagonal pores. Similarly, the FT-IR and EDX results have proved that Zr-MCM-41 was sulfonated. The Brønsted acidic and Lewis acidic sites were identified by NH 3-TPD analysis. Among the sulfonated Zr-MCM-41 catalysts, S-15Zr-MCM-41 has shown 70% cellulose conversion with 16.4% selectivity of 5-hydroxymethyl furfural at 170 °C for 2 h which was higher than other catalysts. It was attributed to the high ratio of Brønsted acidic to Lewis acidic sites.
