Facile production of a large-area flexible TiO₂/carbon cloth for dye removal

Abstract

Through the precoating of TiO 2 on carbon fiber sheet and the subsequent hydrothermal reaction of the coated species with NaOH and tetrabutyl titanate, we successfully demonstrated the engineering growth of TiO 2 nanofibers on carbon fiber sheet. The resulting cloth exhibits excellent flexibility and enables robust, large-area ($300 cm 2 ) fabrication, representing a significant advantage over previous brittle, small area nanofibrous macroscopic structures. The adsorption and photodecomposition of Rhodamine B in water showed that the resulting cloth is very convenient for the purification of contaminated water owing to its combined adsorption and cleaning function. This work provides new insight into the construction of a large area, flexible and robust water purification membrane material.

Mechanically stable and photocatalytically active TiO2/SiO2hybrid films on flexible organic substrates

“…There is nowadays a strong interest to develop exible coatings for application on organic substrates (polyurethane, polyester, polyvinylchloride, and polymethylmetacrylate) related to the photovoltaic, textile or paper industries. [1][2][3][4][5][6][7][8][9] The main problem is that with coatings of pure TiO 2 , the organic substrate is strongly damaged by photocatalytic reactions at the interface with the titania lm. 10,11 Moreover, the photocatalytic coatings are oen rather instable and tend to release photocatalytic particles into the environment.…”

Synthesis of highly permeable Fe2O3/ZnO hollow spheres for printable photocatalysis

“…A solution to the problem is to load the powdered photocatalysts on the recyclable substrates. 23,24 Recently, paper and paper-like substrates have fascinated researchers to fabricate paper-based energy and electronics devices, based on nanoparticles, thin lms, and the transfer of one-dimensional and two-dimensional nanostructures. The prototype devices, such as paper batteries and supercapacitors, 25 thin lm transistors, 26 electronic paper displays, 27 printed circuit boards, 28 and active-matrix organic light emitting diodes, exhibit exceptional technological attributes and commercial perspectives.…”

Synthesis of metal halide perovskites for photoredox catalysis, photoelectgric devices, and solid-state characterization of main group materials

“…In the 18 th century, the Industrial Revolution lit up the light for a modern world but led to the over-exploitation of natural resources and severe environmental pollution due to the severe impact of human activities. As the third industrial revolution unfolds and flourishes, the modernization of the human society has resulted in even higher energy consumption (+2.2% growth in 2017), 1 despite the fact that the global population growth has steadily slowed down in the last decade. Meanwhile, the history continues to unfold in a very similar way: huge amounts of daily exhausts are being released as pollutants to the atmosphere, tremendous amounts of solid wastes containing toxic materials are being dumped and buried in soil, trillions of liters of liquid wastes charged with hazardous chemicals are being disposed into rivers and oceans.…”

“…5 However, solar power is still highly underutilized despite of the fact that solar panel technology is constantly improving and has been well commercialized. 1 Singapore, for instance, receives over 100 times as much energy as we use from solar energy, of which at least 10% can be realistically harnessed with current photovoltaic technology. Another drawback of the solar panel is the lack of efficient approach for the storage and transit of power with the concern of uneven distribution of sun light on this planet.…”

“…Entries 1 -7: Indoline, 1 ABSTRACT: Mechanochemistry is a green, solid-state, re-emerging synthetic technique that can rapidly and efficiently form complex molecules and materials without exogenous heat or solvent(s). Herein, we report the application of solvent-free mechanochemical ball milling for the synthesis of metal halide perovskites, to overcome problems with solutionbased syntheses like phase impurity, high preparation temperatures, and poor reagent solubilities.…”
