However, several important physicochemical parameters (e.g., pH, temperature, and water quality) can influence the adsorption performance of MXenes. Additionally some important challenging issues regarding the toxicity, degradability, storage, and large scale/commercial production of MXenes are still need to be evaluated. The aggregation of MXenes is also a critical challenge, which can reduce the adsorption activity and surface area of these materials; the surface chemistry of MXenes and related mechanisms of contaminants removal by these materials should be analytically and systematically evaluated. Importantly, the environmental risks of MXene-based structures should also be broadly analyzed. This review delineates the pros and cons and critical issues pertaining to the deployment of MXenes endowed with their superior surface area, high selectivity/sensitivity, recyclability, and attractive mechanical properties for removing hazardous pollutants (e.g., antibiotics, dyes, pesticides, heavy metals, pharmaceutical compounds, and radionuclides) from water and wastewater.

These analyses could be made considerably more robust with simultaneous characterization of the XPS of the metal 3p features as well as the 2p features. In these comments, we provide a perspective on the conceptual and theoretical framework needed to extract chemical information from the complex multiplet structure of the 3p XPS of Fe oxides as representative of 3d transition metal oxides. We also present information about a novel kind of many-body effects that may contribute to a further redistribution of the Fe 3p XPS intensity. The concern here is not to develop a complicated mathematical formalism but to explain the complexity in terms of fundamental quantum mechanical concepts. This is done on the basis of ab initio Dirac Hartree–Fock wavefunctions where we examine the physical nature of the 3p XPS features of the representative ferrous and ferric oxides of FeO and Fe2O3, respectively. The key objectives of this paper are as follows: (1) to demonstrate the importance of the angular momentum coupling of open shell electrons, which is done more easily with RS multiplets; (2) to show that a single configuration description of the final state multiplets is woefully inadequate; (3) to identify a novel atomic many-body effect that can lead to a rich satellite structure. The considerations discussed here should have implications for making useful interpretations of the XPS of lower BE levels of other ionic, high spin materials.

This is because on an industrial scale 1,2-diols are prepared via a two-step procedure. Still, it is a challenge to prepare and apply osmium catalysts in dihydroxylation catalysis because of their safety and environmental implications; e.g., volatile, highly toxic, product contamination, etc. To date, few efforts were reported to comprehensively overcome these drawbacks with great success by heterogenizing to an insoluble matrix, including diminishment in catalytic performance. Hence, the need for efficacious solid-supported osmium catalysts to subdue these difficulties is a topic of great importance. This mini review provides a concise overview of some of the most encouraging solid-supported osmium catalysts reported over the last few years, which proved to be more efficient under mild conditions as opposed to other immobilized osmium catalytic systems. The summary discusses the latest developments in the synthetic heterogenizing and homogenization strategies, structure analysis and investigation toward symmetric and asymmetric dihydroxylation for diol production. Specific emphasis is focused on their mechanistic considerations, their reusability and improvement in their safety, and environmental implications.

Therefore, there is a high demand for developing green, environmentally friendly, and cost-effective synthetic tactics, which can reduce or eliminate the rigorousness and complications of the conventional approaches. These nanophotocatalysts have shown high stability, good recyclability, and remarkable catalytic activity. Typically, the significant specific surface areas, the abundant functional groups, large amounts of active sites are the important advantages of the nanoscaled structures for highly photocatalytic degradation of organic pollutants. However, more elaborative studies are still needed to overcome some important limitations/drawbacks of nanophotocatalysts for industrial applications, which include the difficult separation, low selectivity, aggregation/sedimentation, low-usage of visible light, fast charge recombination, and low migration potential of photo-generated electrons and holes. This review highlights recent advances related to the greener and eco-friendly synthesis of nanophotocatalysts, as well as their environmental photocatalytic applications.

The synthesized linker Schiff base was designed to be used in preparation of a new cadmium-based metal-organic framework (Cd-MOF) by sonochemical synthesis, and characterized by using Fourier-transform infrared spectroscopy (FT-IR), powder X-ray diffraction (PXRD), Brunauer-Emmett-Teller (BET), scanning electron microscope (SEM), energy dispersive X-ray (EDX), and thermal analysis. Under an optimum set of synthesis conditions, uniform cubic crystals with average size 44–69 nm and a Langmuir surface area of 163.461 m2/g were produced within 60–75 min by crystal system orthorhombic.

The proposed carbon paste electrode showed a Nernstian slope of 30.15 ± 0.35 mV decade−1 covering a linear range of 1.0 × 10−7 – 1.0 × 10−1 mol L−1 and the detection limit was 7.5 × 10−8 mol L−1 with long-time stability of more than two months over pH range of 2.5–6.5 and fast response time of 10 s.

Finally, 21 relevant full-text articles, which consisted of crystal size data, were selected to conduct this systematic review study. The relevant publications were from 2005 to 2019. In 14 studies (66.67%), Fe-doped TiO2 was prepared by sol-gel method. In many of the studies related to sol-gel method, crystal sizes range from 5 to 25 nm. Among the applied methods for preparation of Fe-doped TiO2, ultrasonic and microwave methods on crystal sizes 58 nm and 170.24 nm were the highest volume. In general, even though the studies used the same procedures, they reported different results. It is concluded that in these studies, in addition to preparation methods, other parameters could be effected on the crystal sizes, such as type of Ti procurers.
