Novel Sm2Ti2O7/SmCrO3 heterojunction based composite photocatalyst for degradation of Rhodamine 6G dye

n-La2Ti2O7/p-LaCrO3: a novel heterojunction based composite photocatalyst with enhanced photoactivity towards hydrogen production

“…An interesting thing to note when La 2 (NO) 3 $6H 2 O, TiO 2 , urea and Cr 2 O 3 are taken together is that no LaCrO 3 phase is formed as it was formed in the previous cases. 14,18 It is concluded that the formation of LaCrO 3 is suppressed by La 2 Ti 2 O 7 . La 2 Ti 2 O 7 is in a more active phase compared to LaCrO 3 .…”

“…[24][25][26][27] When rare earth chromate forms a heterojunction with rare earth titanates, the photoactivity of the system is transferred towards the visible region. 14,18 In general, rare earth chromates are p-type photocatalysts; in the process of forming a heterojunction with rare earth titanates (generally n type), the Fermi level of both align to a position and facilitate the transfer of a Academy of Scientic and Innovative Research, New Delhi, India b Bioresource Engineering Department, CSIR-Institute of Minerals and Materials Technology, Bhubaneswar-751 013, Odisha, India electron from p-type to n-type photocatalyst. In this manner, photogenerated charge carriers are accumulated on different surfaces, enhancing the photoactivity.…”

Characterization and mechanism of MoS2/CdS composite photocatalyst used for hydrogen production from water splitting under visible light

“…The electron transfer process from CdS to MoS 2 realized the separation of electron-hole pairs and prevented the recombination. When the amount of photo-induced electrons kept the same and the recombination was suppressed, more photo-induce electrons were used to produce hydrogen and the hydrogen production rate would be subsequently improved [37].…”

Sol-gel Preparation of Photocatalytic Sm2Ti2O7/HZSM-5 Composite on Degradation of Reactive Brilliant Red X-3B

“…Masayoshi Uno reported the visible light response by Sm2Ti2O7 on photocatalytic generation of hydrogen [10]. Nashim prepared a composite Sm2Ti2O7/SmCrO3 for photocatalytic degradation of rhodamine dyes [11]. Akio Ishikawa introduced the doping of sulfur into Sm2Ti2O7 to prepare Sm2Ti2S2O5 for the enhanced activity on water splitting [12].…”
