Reusable cubic porous light-storing assisted photodegradation composite Sr2MgSi2O7:Eu2+,Dy3+/Ag3PO4 device with adsorption-photocatalysis effects for dark degradation

Visible-light persulfate activation by a BiOI/BiOCOOH composite photocatalyst for accelerated organic pollutant degradation

“…In addition, it can also be found that IB samples with a high adsorption rate also have a higher photodegradation rate of CIP; thus, adsorption is favorable for the subsequent photocatalytic degradation process, which is consistent with the results of previous studies. 28,30,31 Fig. 7(b) shows the effect of the 0.5 IB dosage (10-60 mg) on CIP removal by activated PS.…”

A brief review: the application of long afterglow luminescent materials in environmental remediation

“…The Sr 2 MgSi 2 O 7 :Eu 2+ , Dy 3+ /Ag 3 PO 4 (SMSED/APO) composite as a cubic porous material was combined through an in situ growth method by Wang's group. 48 The degradation effect of SMSED/APO was tested by using degradation rate of three different organic dyes under UV light and at night, where among them, the degradation of RhB was the fastest, which was ascribed to the pore structure energy-saving assisting photodegradation, achieving 80% degradation efficiency through 1/3 APO, and SMSED/APO could be recycled several times. APO possesses good catalytic effects, which was proven by its electron–hole separation rate, and APO was incorporated with Sr 2 MgSi 2 O 7 :Eu 2+ , Dy 3+ to lengthen the photocatalytic time as a round-the clock light source to excite the photocatalytic reactions, no longer depending on light conditions.…”
