“…BiPO 4 is a stable, green, and good ultraviolet-photocatalytic nanomaterial, but the visible light absorption of BiPO 4 is poor, leading to low utilization of sunlight [ 6 , 7 ]. Modification of BiPO 4 helps to enhance the visible light absorption and achieve optimization of photocatalytic performance [ 8 , 9 , 10 , 11 , 12 , 13 , 14 ]. Combined with a suitable semiconductor, it is a common and effective way to improve the photocatalytic performance of BiPO 4 [ 10 , 11 , 12 ].…”

Intelligentization of materials and structures is an important trend. Herein, the stimuli-responsive 4D aerogel is used as a smart substrate for rapid reduction in tetracycline (TC) pollution, in which this smart stimuli-responsive substrate is designated as P4D. Its fourth dimension originates from stimuli-responsive characteristics with time evolution. Meanwhile, the covalent organic frameworks (COFs) composite is constructed by BiPO4 and triazine-based sp2 carbon-conjugated g-C18N3-COF (COF-1), which is another key aspect of COF-1/BiPO4@P4D for rapid photocatalytic degradation regarding TC pollution. This emerging smart structure of COFs@P4D can fix programmable temporary state and recover permanent state under thermal or water stimulus without any complicated equipment. Its performance can be tailored by structure, composition, and function. Compared with traditional powder-form photocatalysts, this stimuli-responsive structure provides attractive advantages, such as high permeable framework, self-adaptivity, flexibly customized functional groups, and fast reduction in TC pollution. The predictable development of COFs@P4D could draw much attention for various promising applications in pollution treatment and sensors.

Pollution of water resources is one of the main concerns of many countries. This issue originates from the entry of diverse pollutants, including dye compounds, into water sources. In this work, ternary Zn-Cu-Cr layered double hydroxides (LDH) supported on graphitic carbon nitride (g-C 3 N 5 ) decorated by silver nanoparticles (C 3 N 5 -LDH-Ag) was rst prepared. Application of various characterization techniques such as SEM, XRD, and FT-IR revealed that the synthesized nanocomposite was composed of Zn-Cu-Cr LDH nanoparticles, g-C 3 N 4 nanosheets, and Ag nanoparticles. The prepared nanomaterials were employed for the photodegradation of tartrazine in aqueous solutions. It was found that the C 3 N 5 -LDH-Ag catalyst outperformed their pure g-C 3 N 5 , Zn-Cu-Cr LDH, and C 3 N 5 -LDH composite in photocatalytic degradation of tartrazine under visible light irradiation. Tartrazine (20 mg/L) can be entirely removed by 0.25 g/L C 3 N 5 -LDH-Ag photocatalyst under one h visible light irradiation (200W) at pH 6 with a rapid degradation rate constant (k) that is 4.4, 3.9, and 2.6 times higher than that of pure C 3 N 5 , Zn-Cu-Cr LDH, and C 3 N 5 -LDH component, respectively. The formation of hydroxyl radicals on the surface of C 3 N 5 -LDH-Ag as the main active species was approved by the capturing experiment. The nding results approved the stability and reusability of C 3 N 5 -LDH-Ag in four photocatalytic degradation cycles. In general, our ndings revealed that the synthesized nanocomposite could be employed as an e cient photocatalyst in environmental remediation.
