Effect of Xe ion irradiation on photocatalytic performance of oblique TiO2 nanowire arrays

Role of Ag2S coupling on enhancing the visible-light-induced catalytic property of TiO2 nanorod arrays

“…To improve the photocatalytic performance of this binary system, prospective researches could be considered including modifying treatment such as ion irradiation 32 , (rapid) thermal annealing 26 33 , strong magnetic fields 34 and their synergy effect 35 . Moreover, promising techniques such as ion implantation 36 and light etching 37 induced patterning could be used to control the substrate for synthesizing NRAs.…”

Effect of nitrogen ion irradiation treatment to the enhancement of ZnO photocatalytic performance

“…The test process lasted for 75 minutes in a 50‐W Xe light source, and each irradiation interval was 15 minutes. According to the Lambert‐Beer law, the MO photo‐degradation rate can be expressed by Equation (1) as follows: where D stands for the photo‐degradation rate, c 0 and c t are the concentration of MO before and after illumination, and A 0 and A t are the absorption of MO before and after illumination, respectively.…”

“…Moreover, the carriers of ZnO are easy to recombine, making it hard to maintain good photocatalytic performance . Many literatures have adopted different methods to improve the performance of zinc oxide, including ion doping, thermal annealing treatment, and surface modification …”

“…Ion irradiation as one of the modification methods has drawn great interest in many research fields, and most of which focused on the mechanical behaviors, optical and electric properties, and photocatalytic properties . There have been few reports on applying ion irradiation methods on modifying the photocatalytic performance.…”

“…So it is a very important and urgent challenge to find proper semiconducting material which can produce H 2 and O 2 through a photocatalytic reaction. TiO 2 NPs was discovered in 1972 and is one of the best photocatalysts among the semiconducting metal oxides nanoparticles [1][2][3][4][5][6]. Rutile structured SnO 2 NPs was studied extensively after TiO 2 NPs because SnO 2 NPs possess high surface area and temperature resistance, low toxicity and high ability does redox reactions with gases [7].…”
