“…The formed heterojunction interfaces are believed to make available the migration of photo‐induced h + to the ZIF‐67 by leaving the e − in the CB of g‐C 3 N 4 under visible light irradiation, which can be restraining the change of charge recombination and gather freer e − in the CB of g‐C 3 N 4. Generally, in the photocatalytic procedure, most of the photogenerated e − and h + will recombine inside the catalyst, and partial holes transferred to the catalyst surface will directly decompose dyes/react with the adsorbed H 2 O to produce (•OH) radicals to contribute in dye degradation . The remaining e − will react with O 2 to form • O 2 − and then react with protons to form HOO.…”

Herein, cobalt (Co)‐based metal–organic zeolitic imidazole frameworks (ZIF‐67) coupled with g‐C3N4 nanosheets synthesized via a simple microwave irradiation method. SEM, TEM and HR‐TEM results showed that ZIF‐67 were uniformly dispersed on g‐C3N4 surfaces and had a rhombic dodecahedron shape. The photocatalytic properties of g‐C3N4/ZIF‐67 nanocomposite were evaluated by photocatalytic dye degradation of crystal violet (CV), 4‐chlorophenol (4‐CP) and photocatalytic hydrogen (H2) production. In presence of visible light illumination, the photocatalytic dye results showed that 95% CV degradation and 53% 4‐CP degradation within 80 min. The H2 production of the g‐C3N4/ZIF‐67 composite was 2084 μmol g−1, which is 3.84 folds greater than that of bare g‐C3N4 (541 μmol g−1).

Water shortage and the energy crisis are two major global challenges in this century. The solution for water crisis should be based on a sustainable energy source. Solar‐inspired water purification is an efficient and green technology for tackling the water challenge using abundant and clean solar energy through photothermal evaporation‐induced water production, photoinduced antimicrobial treatment, and photocatalytic degradation of organic contaminants. 2D nanomaterials draw significant attention for their use these three water‐purification methods because of their large surface area, broadband and strong absorption in the solar spectral range, and efficient photothermal and photocatalytic transformation. Herein, the recent development of 2D nanomaterials applied in photothermal evaporation, photoinduced antimicrobial treatment, and photocatalytic capability is comprehensively overviewed. Various strategies in enhancing the light‐absorption and light‐conversion efficiency for different 2D nanomaterials are presented. The challenges and perspectives of these 2D nanomaterials are further discussed for practical water purification. This Review highlights these green energy–driven water‐purification methods based on emerging 2D materials.

“…The photocatalytic degradation of organic pollutants in wastewater is an attractive, environmentally friendly and green method that offers a way to harness solar power efficiently and convert them into non-toxic degradation products [1,2,3,4,5,6,7,8]. Recently, although great progress has been made in the field of photocatalysis, only few photocatalysts can effectively use visible light in the degradation of organic pollutions.…”

Construction of a CQDs/Ag3PO4/BiPO4 Heterostructure Photocatalyst with Enhanced Photocatalytic Degradation of Rhodamine B under Simulated Solar Irradiation

A carbon quantum dot (CQDs)/Ag3PO4/BiPO4 heterostructure photocatalyst was constructed by a simple hydrothermal synthesis method. The as-prepared CQDs/Ag3PO4/BiPO4 photocatalyst has been characterized in detail by X-ray diffraction, field-emission scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy, ultraviolet–visible spectroscopy, and photoelectrochemical measurements. It is demonstrated that the CQDs/Ag3PO4/BiPO4 composite is constructed by assembling Ag3PO4 fine particles and CQDs on the surface of rice-like BiPO4 granules. The CQDs/Ag3PO4/BiPO4 heterostructure photocatalyst exhibits a higher photocatalytic activity for the degradation of the rhodamine B dye than that of Ag3PO4, BiPO4, and Ag3PO4/BiPO4. The synergistic effects of light absorption capacity, band edge position, separation, and utilization efficiency of photogenerated carriers play the key role for the enhanced photodegradation of the rhodamine B dye.
