Functionalized waste cellulose with metal-organic-frameworks as the adsorbent with adjustable pore size: Ultralight, effective, and selective removal of organic dyes

Sustainable fabrication of a novel ZIF-67 modified with Atriplex halimus-mediated MoO3/GO-NH2 for expeditious removal of nitrophenol

“…The stretching mode of C=N appeared at 1569 cm −1 , and the C-H stretching in the aliphatic chain and aromatic ring manifested at 2920 and 3180 cm −1 (Tang et al 2018). The peak at 424 cm −1 belongs to Co-N in ZIF-67 (Zhang et al 2021). The MoO 3 /ZIF-67/ AmGO spectrum represents the distinctive peaks of ZIF-67, MoO 3 , and AmGO, implying a well combination between these components.…”

Recent Progresses in Adsorption Mechanism, Architectures, Electrode Materials and Applications for Advanced Electrosorption System: A Review

“…Furthermore, this group synthesized porous MXene/SWCNTs film as a CDI electrode for the removal of organic dyes in wastewater ( Figure 5 f–j), and the maximum adsorption capacity was as high as 28,403.7 mg/g when applying −2.4 V voltage [ 106 ]. In addition, our group prepared carbon foam electrodes derived from waste cigarette filters/zeolitic-imidazolate frameworks-8 (ZIF-8) composites [ 6 , 7 , 8 , 9 , 10 , 107 ], and found that the maximum electrosorption capacity of MB for these carbon foams reached to 1846.7 mg/g when applying −1.2 V voltage. Under most conditions, the adsorption time of methyl orange (MO) solution using most water treatment methods is more than 1 h. Whereas, Liu and co-workers used the holey graphene hydrogel (R-HGH) prepared by one-step hydrothermal method as the CDI electrode [ 108 ].…”

“…Globally, water pollution has become a hot topic in recent years. In order to address this issue, chemical precipitation, membrane separation, ion exchange, distillation, adsorption and other technologies have been proposed by researchers [ 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 ]. In general, ordinary adsorbents have been widely used in the field of water treatment due to the simple operation process.…”

Concave Gold Nanocubes Exhibit Growth-Etching Behavior: Unexpected Morphological Transformations

“…The minute scale and expansive surface area inherent to nanomaterials introduce intricate interactions with the surrounding milieu, which, in turn, exert an impact on the equilibrium of chemical reactions involving these exceptional materials. It is widely acknowledged that nanoparticles exhibiting high-index facets tend to exhibit heightened reactivity, attributed to the increased density, low-coordination facets, and edges that facilitate reactions on their surfaces. − Prior research has also delineated the division of nanoparticle surfaces into mobile and immobile phases to prognosticate surface chemical potential, thus contributing to the comprehension of the equilibrium of dissolving nanomaterials . The dissolution of nanodiscs during storage after synthesis was observed due to the Ostwald ripening mechanism, irrelevant to the oxidizing species in solution .…”
