Enhanced solar photocatalytic activity of Er3+:YAlO3-loaded BiPO4 composite

Response to Comment on “Intimate Coupling of Photocatalysis and Biodegradation for Degrading Phenol Using Different Light Types: Visible Light vs UV Light”

“…Later, Xu and Jiang demonstrated the visible-to-ultraviolet upconversion in Er 3+ :YAlO 3 with 542.4 and 548.8 nm laser excitation . Although the upconversion efficiency for Er 3+ :YAlO 3 has not been calculated to date, different research groups showed that successful excitation of photocatalysts, such as TiO 2 , ZnO and BiPO 4 , by the UV upconverted from the visible or solar light with use of Er 3+ :YAlO 3 . Similarly, Er 3+ :YFeO 3 was also confirmed by Hou et al to convert the visible light (wavelength higher than 430 nm) to UV and then excite TiO 2 for photocatalysis .…”

Novel synthesis of cerium oxide nano photocatalyst by a hydrothermal method

“…In recent years, along with, the application of nanoscience using various metals such as magnesium oxide (MgO), nanosilicon (Si), silver oxide (Ag 2 O), zinc oxide (ZnO), copper oxide (CuO), gold (Au), titanium dioxide (TiO 2 ) and calcium oxide (CaO) were studied [12] . The one of the anatase phase TiO 2 metal oxide nano particles was synthesised facile solutions phase method without use of surfactant from titani-um isopropoxide and different alcoholic medium (methanol, ethanol, propanol and butanol) and also demonstrated their excellent performance in photo degrading methylene blue and bisphenol aqueous solution by using UV-A light irradiation [13] .…”

“…Qi et al synthesized a series of fullerene (C 60 )-modified anatase TiO 2 (a-TiO 2 ) nanocomposites by an effortless solution phase method and also investigated photocatalytic degradation of methylene blue (MB) under UV-A light irradiation [14] . Zhang et al successfully reported the photodegradation of methylene blue (MB) solution under a simulated solar light irradiation by Er 3+ :YAlO 3 loaded.…”

The formation mechanism of a Er3+-doped heterojunction ms/tz-BiVO4 with enhanced photocatalytic performance under visible light

“…Lots of researches on Er 3+doped systems have been reported for the richer spectra of Er 3+ in the NIR-UV range, which showed the successfully cooperative electronic and luminescence mechanism. 25,26 With lanthanide doping in the BiVO 4 , a heterojunction structure is obtained in which the ms-BiVO 4 and tz-BiVO 4 are coexisting. And the photocatalytic activities of this catalyst have been greatly improved.…”
