“…[12] Owing to the presence of different vacancies, ions and small molecules can permeate the PB structure, which allows for charge balance during the redox process. As ar esult of these characteristics, PB and its analogues [general hexacyanometallates (HCMs), in which iron speciesa re replacedb yd ifferent metals]a re widely studied for applications such as electrochromic devices, [13] batteries electrodes, [14] electrochemical sensors, [15] molecular magnets, [16] catalysts, [17] water splitting, [18] and hydrogen storage.

Most of the dye-sensitized solar cells (DSSCs) developed so far use organic electrolytes and water-sensible sensitizers. The search for aqueous DSSCs, a promising technology for solar-energy conversion, implies finding materials that are stable in aqueous solution. In this study, Prussian blue (PB) was utilized as an innovative sensitizer in a photoanode for DSSCs and a novel synthetic approach to a carbon nanotubes/TiO /PB nanocomposite thin film was developed. The photoresponse was evaluated in a total aqueous electrolyte, and photocurrents of 600 μA cm were achieved.

challenging mainly because of their lower ionic conductivity and high relaxation period. In mono-electrochrome (i.e., with a single active EC layer) ECD configurations, an ion-conducting SPE is sandwiched between two transparent conducting oxide coated glass, one of which is laminated with the functional coating. The working mechanism of the ECDs resembles a thin film electrochemical cell, prompting contemporary EC researchers to explore the possibility of integrating ECDs with other electrochemical energy storage devices such as batteries, [2,3] supercapacitors, [4][5][6] and pseudocapacitors. [7,8] Yang et al. [9] published an excellent review that outlines potential impact areas of these efforts. Tian et al. [10] reported the manufacturing of a W 18 O 49 /polyaniline (PANI) based energy level indicating smart supercapacitor electrode that displayed continuous color variations as a response to changing levels of stored energy. Very recently, an ultrafast-charging, high-capacity Al-tungsten oxide based electrochromic battery has been demonstrated by Zhao et al. [11] that showed a sevenfold enhancement in the discharge capacity compared to the other reported works.One substantial challenge in integrating these technologies resides in their mismatched operational requirements. Abruña et al. [12] critically described these differences by noting that the electrolytes are typically the weak-links as many electrochemical systems often push the thermodynamic stability limit for the electrolytes. Additionally, while the ECDs and batteries are designed specifically for a longer storage life, the capacitive charge storage devices require very high cycling efficiency. In a review article, Yang et al. [9] described the challenges in fabricating electrochromic energy system for simultaneous realization of electrochromism and energy storage. They pointed out that high quality ECDs are required to produce a faster and higher response in the optical density against a low charge density. However, batteries or supercapacitors must show a high charge density that significantly compromises the performance of an integrated device. In one section of their review article, Varzi et al. [13] highlighted the challenges associated with charge and mass transport in the Li + containing solid polymer electrolytes for batteries. The discussion is relevant for constructing ECDs as well for Li + ion based systems that offer more stability than an acidic system. A comprehensive list of dissimilarities in operational requirements between the ECD There are ongoing efforts to integrate electrochromic device (ECD) technology with other electrochemical systems. ECDs made with safer "solid" polymer electrolytes (SPEs) are prone to performance degradations due to their high relaxation period that is detrimental to highly dynamic switching operations. Here, the fabrication of partially crystalline WO 3 based all-solid-state mono-electrochrome switches is reported that shows outstanding optical and electrical stability under prolonged charge-discharge cy...

Multi-walled carbon nanotubes (MWCNTs) filled with different species of cobalt (metallic cobalt, cobalt oxide) were synthesized by a chemical vapor deposition method through cobaltocene pyrolysis. A systematic study was performed to correlate different experimental conditions with the structure and characteristics of the obtained material. Thin films of Co-filled CNTs were deposited over conductive substrates through a liquid-liquid interfacial method and were used for cobalt hexacyanoferrate (CoHCFe) electrodeposition by an innovative route in which the Co species encapsulated in the CNTs were employed as reactants. The CNT/CoHCFe films were characterized by different spectroscopic, microscopic, and electrochemical techniques and presented high electrochemical stability in different media. The nanocomposites were applied as both an electrochemical sensor to H2 O2 and a cathode for ion batteries and showed limits of detection at approximately 3.7 nmol L(-1) and a capacity of 130 mAh g(-1) at a current density of 5 A g(-1) .
