Ag nanowire-modified 1D α-Fe2O3 nanotube arrays for photocatalytic degradation of methylene blue

Construction of an α-Fe2O3/Bi2O3 p–n heterojunction with exceptional visible-light photocatalytic performance for dye removal

“…4 However, its short transmission length (2-4 nm), slow charge migration kinetics and low oxidation power hinder the practical application of a-Fe 2 O 3 . 5 Different strategies, including morphology control, 6 heterojunction construction 7,8 and doping with metals or nonmetals, 9 have been adopted to solve these problems. Hence, it is an effective approach to fabricate highly uniform Fe 2 O 3 nanotube arrays on iron substrates using an electrochemical anode method.…”

PREPARATION AND CHARACTERIZATION OF VISIBLE-LIGHT-DRIVEN Ce-DOPED CdS NANOWIRES FOR PHOTODEGRADATION OF RHODAMINE B

“…[28][29][30][31]. Upon the addition of IPA and BQ, the photodegradation of RhB was greatly restrained because IPA and BQ trapped the• OH and • O 2 radicals.…”

Core/Shell Ag/SnO2 Nanowires for Visible Light Photocatalysis

“…Another, more stable semiconductor of TiO2 that was combined with various Ag nanostructures revealed photocatalytic activity that was characterized by a degradation time of 60 min [27] and more than 90 min [28], but under UVlight. Ag nanowires that were modified with an α-Fe2O3 show similar efficiency and time of the process; methylene blue was degraded for 30 min under visible light illumination, according to the authors, due to the synergetic effect of LSPR and the effective separation of photogenerated carriers between both materials [29]. A ternary TiO2/Ag/SnO2 system was applied for the photodegradation of methylene blue for more than 140 min for 40 mg of the photocatalyst of 3.12 × 10 −5 methylene blue (100 mL) under visible light irradiation [5].…”
