Controllable Synthesis and Photocatalytic Activity of Anatase TiO2 Single Crystals with Exposed {110} Facets

Photodegradation of phenol by N-Doped TiO2 anatase/rutile nanorods assembled microsphere under UV and visible light irradiation

“…The UV irradiation absorption can be equal or higher than the band gap value of 3.2 eV for anatase or 3.0 eV for rutile [4,5]. TiO 2 exists in three distinct polymorphs, which are anatase, rutile (both tetragonal crystal systems), and brookite (orthorhombic crystal system) [6,7]. A previous study on the band gap alignment of rutile and anatase TiO 2 has proven that the mixed phase of anatase/rutile TiO 2 has synergistic effects and higher photocatalytic activity as compared to pure phase of either in anatase or rutile [4].…”

“…The highly crystalline TiO 2 nanoparticles can be prepared via solegel method, and followed by heat treatment that ranges from 0 to 600 C [25,29]. It has been reported that the high quality of mixed phase of anatase/rutile TiO 2 nanoparticles, which contributes to high photocatalytic activity, can also be obtained by manipulating the types of reagents and heat treatment conditions [7,30,31]. However, to the best of our knowledge, there is hardly a report on the simple and direct preparation of nitrogen doped anatase-rutile mixed phase TiO 2 nanostructures [32,33].…”

Review of development of phase change cold storage technology for food cold chain application

“…In the 1970s, many scholars from the United States, Britain, Canada and other countries also have a wide range of research on this project, and there is fresh cold storage using ice cold storage and cooled wet air for flowers, vegetables and fruit preservation in foreign countries. LiyuanWu, Kangning Guo, Wen Su [6,7,8] etc, have also put forward to cool the condensed water down for cold storage at night to lower the condensation temperature, and they have basically completed the theoretical and experimental model of wet cooling system. Hold-over plate refrigerated storage.…”

“…1 and Fig. 2 respectively show top-mounted and side-mounted installation methods of the cold storage plate and refrigeration pipe [6]. Our country has the huge potential for the cold chain transportation market, but the cold chain logistics foundation is weak, it is difficult to narrow the gap with the developed countries in a period of time [9].…”

Enlarging {110} exposed facets of anatase TiO2by the synergistic action of capping agents

“…1,5−8 Although it has been anticipated that {110} facets of anatase TiO 2 possess the highest photoelectric and photocatalytic performances, the synthesis of {110} facetexposed anatase TiO 2 has rarely been reported. 1 18 Recently, we also synthesized anatase TiO 2 microcrystals containing minor {110} facets using TiCl 3 as titanium source and HF as the capping agent. 19 By the unremitting efforts of the researchers, the percentage of highly reactive {001} facets in anatase TiO 2 has been increased to nearly 98.7%.…”
