“…After pretreatment, the biodegradability of the water matrix was significantly improved, which means that the remaining low-toxicity organic interferents may be promising for removal by biological treatment . As shown, MIT represents extremely high selectivity toward targets . Even when it is in the presence of other pollutants, only the targeted pollutant can be removed.…”

Characteristic emerging pollutants at low concentration have raised much attention for causing a bottleneck in water remediation, especially in complex water matrices where high concentration of interferents coexist. In the future, tailored treatment methods are therefore of increasing significance for accurate removal of target pollutants in different water matrices. This critical review focuses on the overall strategies for accurately removing highly toxic emerging pollutants in the presence of typical interferents. The main difficulties hindering the improvement of selectivity in complex matrices are analyzed, implying that it is difficult to adopt a universal approach for multiple targets and water substrates. Selective methods based on assorted principles are proposed aiming to improve the anti-interference ability. Thus, typical approaches and fundamentals to achieve selectivity are subsequently summarized including their mechanism, superiority and inferior position, application scope, improvement method and the bottlenecks. The results show that different methods may be applicable to certain conditions and target pollutants. To better understand the mechanism of each selective method and further select the appropriate method, advanced methods for qualitative and quantitative characterization of selectivity are presented. The processes of adsorption, interaction, electron transfer, and bond breaking are discussed. Some comparable selective quantitative methods are helpful for promoting the development of related fields. The research framework of selectivity removal and its fundamentals are established. Presently, although continuous advances and remarkable achievements have been attained in the selective removal of characteristic organic pollutants, there are still various substantial challenges and opportunities. It is hopeful to inspire the researches on the new generation of water and wastewater treatment technology, which can selectively and preferentially treat characteristic pollutants, and establish a reliable research framework to lead the direction of environmental science.

“…Benefiting from multiple synergetic effects, the nanohybrids of metal species on semiconductors exhibit various improved photoactivity, which brings more opportunities for achieving the desired applications of photocatalysis in environmental remediation, including oxidation/degradation of organic pollutants, [91–104] conversion of CO 2 , [105–114] reduction of toxic high‐valence metal ions, [115–126] and photocatalytic antibacterial [127–136] …”

“…Third, highly selective photocatalysis should become a new and important research field because it is more applicable to be employed in practical environment containing various interfering species. Having recognition sites with complementary cavity and functional groups to target molecules, molecularly imprinted materials can serve as an alternative component to fabricate metal‐hybridized photocatalysts with high selectivity [136] . Forth, although catalytic reactions can be recycled for unlimited times in theory, the recyclability of hybrid materials in photocatalysis is very difficult to be performed for dozens of times, which can be attributed to the unignorable photocorrosion of semiconductors during photocatalysis.…”

As a promising technique to potentially address the energy crisis and environmental issues, photocatalysis has been reported widely to exhibit various outstanding behaviors in production of new fuels/chemicals and treatment of contaminants. The photocatalytic performance is extremely dependent on the used photocatalysts, so that the design and preparation of efficient photocatalysts are critically important for significantly improving the photocatalytic activity. Among various strategies, the hybridization of metal with semiconductors has recently been attracting more and more research interest owing to their expended spectral absorption, promoted transferring rate of charge carriers and Plasmon‐enhanced effect. In this minireview, the metal‐facilitated hybrid photocatalysts are overviewed comprehensively to first reveal unique functions of metals in improvement of photoactivity and summarize the emerging metal‐involved hybrid systems. Subsequently, the synthetic methods towards hybrid photocatalysts are introduced and their practical applications are emphasized in environmental remediation including degradation of organic pollutants, conversion of harmful gases, treatment of heavy metal ions and sterilization of bacteria. At the end, the challenges for industrializing these hybrid photocatalysts are discussed carefully and future development is suggested rationally.

“…2D materials with an analogous structure to graphite (i.e., weak van der Waals interactions between two adjacent layers, strong covalent bonding interconnecting in-plane atoms) have attracted extraordinary attentions in the last few decades. [1][2][3][4][5][6][7][8][9] On account of the weak interactions between the layers, the materials of the layered structure can readily be exfoliated into mono-or fewlayered nanosheets, and the strong covalent bonds contribute to well-maintained in-plane integrity. These mono-or few-layered nanosheets show some unique physicochemical properties, supercapacitors and batteries because of its intrinsically high N content (57.1 at%), abundant pores and defects.…”

Graphitic carbon nitride (g‐C3N4) have attracted great attention in the field of energy conversion and storage due to its unique layered structure, tunable bandgap, metal‐free characteristic, high physicochemical stability, and easy accessibility. 2D g‐C3N4 nanosheets have the features of short charge/mass transfer path, abundant reactive sites and easy functionalization, which are beneficial to optimizing their performance in different fields. However, the reviews of the comprehensive applications of 2D g‐C3N4 for energy conversion and storage are rare. Herein, this review first introduces the physicochemical properties of bulk g‐C3N4 and g‐C3N4 nanosheets, and then summarizes the synthetic strategies of 2D g‐C3N4 nanosheets in detail, such as thermal oxidation etching, chemical exfoliation, ultrasonication‐assisted liquid phase exfoliation, chemical vapor deposition, and others. Emphasis is focused on the rational design and development of 2D g‐C3N4 nanosheets for the diversified applications in energy conversion and storage, including photocatalytic H2 evolution, CO2 reduction, electrocatalytic H2 evolution, O2 evolution, O2 reduction, alkali‐metal ion batteries, lithium‐metal batteries, lithium–sulfur batteries, metal‐air batteries, and supercapacitors. Finally, the current challenges and perspectives of 2D g‐C3N4 nanosheets for energy conversion and storage applications are discussed.
