“…Visualization of the 3D volume render were performed using Amira. Nuclear magnetic resonance (NMR) 1 H, and 13 C NMR and were recorded at 400 and 101 MHz respectively on a Bruker 400 spectrometer with CDCl 3 as a solvent. All spectra were reported in d (ppm) relative to residual solvent signal (dH (CHCl 3 ) 1 = 4 7.26 ppm).…”

“…[9][10][11] Thus, several green metrics were created in order to compare the sustainability and/or environmental impact of a chemical process. [12,13] Herein, a semi quantitative method based on the 12 principles of green chemistry was used to represent the greenness of the reaction; the green star and mass metrics were used to compare this work to others. [14] The field of catalysis ranges over a broad spectrum of applications, among which is the valorization of toxic compounds.…”

The efficiency of a catalytic process is assessed based on conversion, yield, and time effectiveness. However, these parameters are insufficient for evaluating environmentally sustainable research. As the world is urged to shift towards green catalysis, additional factors such as reaction media, raw material availability, sustainability, waste minimization and catalyst biosafety, need to be considered to accurately determine the efficacy and sustainability of the process. By combining the high porosity and versatility of metal organic frameworks (MOFs) and the activity of gold nanoparticles (AuNPs), efficient, cyclable and biosafe composite catalysts can be achieved. Thus, a composite based on AuNPs and the nanometric flexible porous iron(III) aminoterephthalate MIL‐88B‐NH2 was successfully synthesized and fully characterized. This nanocomposite was tested as catalyst in the reduction of nitroarenes, which were identified as anthropogenic water pollutants, reaching cyclable high conversion rates at short times for different nitroarenes. Both synthesis and catalytic reactions were performed using green conditions, and even further tested in a time‐optimizing one‐pot synthesis and catalysis experiment. The sustainability and environmental impact of the catalytic conditions were assessed by green metrics.

“…Replacing HF with mineral acids that penetrate tissues less readily [16] is an alternative. MIL-101(Cr) syntheses using hydrochloric acid (HCl), [17,55,[57][58][59][60][61][62][63][64][65][66][67] nitric acid (HNO 3 ), [12,18,31,[68][69][70][71][72][73][74][75][76][77][78][79][80][81][82][83][84][85][86][87] and even sulfuric acid (H 2 SO 4 ) [12] as mineralizers have been reported. [11] Although HCl is a stronger acid than HNO 3 , H 2 SO 4 , and HF (Table 3), MIL-101(Cr) synthesized using HCl (denoted HCl-MIL-101(Cr)) in molar ratios such as 1 Cr:1 H 2 BDC:1 HCl:266 H 2 O remains highly crystalline.…”

Among the existing metal–organic frameworks (MOFs), MIL‐101(Cr) is renowned for its stability in air and water. As a result, MIL‐101(Cr) has numerous potential applications ranging from adsorptive cooling to catalysis. The industrial‐scale production of MIL‐101(Cr) is necessary before realizing these applications. Yet, there remain two main bottlenecks in preparing MIL‐101(Cr) in bulk: the toxicity of hydrofluoric acid (HF) used in conventional MIL‐101(Cr) synthesis and the challenge of ensuring that the as‐prepared MIL‐101(Cr) is highly porous with specific Brunauer–Emmett–Teller surface area (SBET) above 4000 m2 g−1. On the laboratory scale, MIL‐101(Cr) often presents SBET 2300–3500 m2 g−1. The synthesis and purification procedures often influence the yield, particle size, porosity, and other properties of MIL‐101(Cr). This critical review examines trends in MIL‐101(Cr) preparation procedures and the MOF's resulting properties to elucidate areas for improvement toward its real‐world applications. The purification processes for conventional HF‐based MIL‐101(Cr) whereby porosities vary despite the same synthesis approach are first investigated. Next, the reported additives for substituting HF and their influence on the resulting MIL‐101(Cr)’s porosity and particle size are discussed. The selection of additives may be application‐specific: exemplified in the examination of MIL‐101(Cr)’s preparation, its corresponding water sorption capacity, and desiccant‐related applications.

“…In synthesis processes, adherence to the principles of green chemistry is becoming more visible. Through novel syntheses, metal-organic structures with high surface areas and porosity for contaminant absorption are now obtained with a 50% reduction in negative environmental impacts thanks to safer procedures, solvents, and auxiliaries [32]. Similarly, polymer manufacturing is more environmentally conscious by consuming less and wasting less [33].…”

Traditional chemistry is undergoing a transition process towards a sustained paradigm shift under the principles of green chemistry. Green chemistry is emerging as a pillar of modern chemistry focused on sustainability. In this context, the aim of this study was to analyse green chemistry research and its contributions using quantity, quality, and structural indicators. For this purpose, data were retrieved from Scopus and Web of Science through a structured search equation for the study period, i.e., 2012 to 2022. These data were compiled and processed in Microsoft Excel version 2307, totalling 2450 records. VOSviewer software, version 1.6.18, was used to map the keyword network and for overlay and density visualisations. The results showed that green chemistry is constantly increasing in different fields of knowledge, with new studies in green solvents, eutectic solvents, and education for sustainable development. The number of publications peaked in 2019, slightly decreasing in subsequent years due to the novel coronavirus disease 2019 (COVID-19) pandemic. As visualised through VOSviewer, the keyword “sustainability” is connected to all clusters, and green synthesis, catalysis, sustainability, curriculum, and higher degrees are leading trends in green chemistry research. The study could benefit researchers and professionals interested in green chemistry and sustainability.
