“…activity of dye-sensitized TiO 2 is achieved under visible light irradiation. Some photocatalysts based on Ru pyridine complex were used widely for wastewater treatment (Medved'ko et al 2017;Saito et al 2004;Trachibana et al 2000;Cho et al 2001;Park et al 2006), but it is limited to practical application because it is expensive and poisonous. How to reduce the cost of sensitizers and their environmental toxicity has been a challenge for obtaining high-efficiency composite photocatalysts.…”

In this paper, the kinetic characteristics and cycle stability of Fe-complex/TiO2 in the process of degradation of phenolic pollutants and reduction of heavy metal Cr(VI) were studied systematically. First, the structural characteristics and photocatalytic activities of Fe(III)-(8-hydroxyquinoline-5-carboxylic acid)-TiO2 (Fe-HQC-TiO2) nanoparticle to degrade phenolic pollutants and reduce Cr(VI) simultaneously had been investigated. Compared with the single degradation, the efficiency of synergistic degradation/reduction had been improved and the degradation/reduction rate had been obviously accelerated. In particular, the cyclic stability of Fe-HQC-TiO2 photocatalyst decreased obviously when it was used to reduce Cr(VI) alone, but it could still keep above 90% after three cycles when it was used for reduction of Cr(VI) and degradation of phenol synergistically. Second, to Fe-HQS/TiO2 nanoparticle or Fe-HQS/TiO2 nanotube (HQS (8-hydroxyquinoline-5-sulfonic acid)), the synergistic degradation/reduction (2,4-dichlorophenol/Cr(VI)) efficiencies were always greater than those of a single degradation/reduction and the time was greatly reduced. All the results indicated that there were interactions between Cr(VI) and phenol or 2,4-dichlorophenol in the photocatalytic process. The possible mechanism of synergistic accelerated degradation of phenolic compounds and reduction of Cr(VI) was proposed by analyzing and testing the surface characteristics of photocatalyst and the properties of photocatalytic system during the synergistic degradation/reduction.

In this paper, the achievements, problems and prospects of creating personalized energy systems based on nanostructured materials are analysed. Various concepts of developing methods and ways of personalized energy provision for autonomous human survival in remote natural habitat, emergency situations of natural disasters and technogenic catastrophes when centralized power supply is unavailable or in an effort to reduce the economic and environmental costs of remote energy production and transportation are also considered. The possibilities and limitations of using traditional and renewable alternative energy sources, processes and devices for extracting, storing and converting their energy into the necessary consumer forms due to fundamental physical laws are discussed as well. The article covers the new nanostructured materials with special functional properties for personalized energy systems development. The mechanisms for formation of the required nanostructures in synthesized materials, especially those with a high content of fractal interfacial formations, are considered as well as methods for studying their structural and phase characteristics that determine the achievability of the specified parameters of model converters and energy storage devices.

“…The corresponding DSSC exhibited an efficiency of 3.4%, which was attributed to the more negative excited state redox potentials and efficient electron injection into the TiO2 conduction band. On the other hand, a cycloruthenated thiophene-based ruthenium sensitizer with orthosubstituted pyridine on metallated thiophene has been developed and exhibited a higher efficiency of 5.3% (dye 24) compared to other known cycloruthenated thiophenes, as a result of its broad metal-to-ligand charge transfer (MLCT) bands and high extinction coefficients [30].…”
