“…The unique properties of inorganic nanoparticles make them suitable for applications in diverse areas, which include nanomedicine (e.g., drug delivery, bioimaging, phototerapies) ( Lin et al, 2007 ; Sokolova and Epple, 2008 ; Trindade and Daniel da Silva, 2011 ; Vega-Vásquez et al, 2020 ; Wang and Mattoussi, 2020 ; Ray and Bandyopadhyay, 2021 ), energy (e.g., solar cells, lightning) ( Kamat, 2008 ; Cheng et al, 2016 ; Kumar et al, 2017 ; Chen et al, 2018 ; Choe et al, 2021 ), environment (e.g., water and air purification ( Theron et al, 2008 ; Kumari et al, 2019 ; Weon et al, 2019 ; Wadhawan et al, 2020 ; Li et al, 2021 ), greenhouse gases capture ( Kumar et al, 2020 ; Cheng et al, 2021 ), sustainable technologies (e.g., catalysis, biological synthesis) ( Polshettiwar and Varma, 2010 ; Dutta et al, 2015 ; Kumari et al, 2020 ; Jeevanandam et al, 2022 ; Liu et al, 2022 ; Wani and Suresh, 2022 ), among many others. These endeavours require transdisciplinary approaches, among which the synthesis and surface modification of the materials are usually regarded at the upstream in the supply chain of functional materials for such devices and processes.…”

Water is the most important resource for all kind forms of live. It is a vital resource distributed unequally across different regions of the globe, with populations already living with water scarcity, a situation that is spreading due to the impact of climate change. The reversal of this tendency and the mitigation of its disastrous consequences is a global challenge posed to Humanity, with the scientific community assuming a major obligation for providing solutions based on scientific knowledge. This article reviews literature concerning the development of nanomaterials for water purification technologies, including collaborative scientific research carried out in our laboratory (nanoLAB@UA) framed by the general activities carried out at the CICECO-Aveiro Institute of Materials. Our research carried out in this specific context has been mainly focused on the synthesis and surface chemical modification of nanomaterials, typically of a colloidal nature, as well as on the evaluation of the relevant properties that arise from the envisaged applications of the materials. As such, the research reviewed here has been guided along three thematic lines: 1) magnetic nanosorbents for water treatment technologies, namely by using biocomposites and graphite-like nanoplatelets; 2) nanocomposites for photocatalysis (e.g., TiO2/Fe3O4 and POM supported graphene oxide photocatalysts; photoactive membranes) and 3) nanostructured substrates for contaminant detection using surface enhanced Raman scattering (SERS), namely polymers loaded with Ag/Au colloids and magneto-plasmonic nanostructures. This research is motivated by the firm believe that these nanomaterials have potential for contributing to the solution of environmental problems and, conversely, will not be part of the problem. Therefore, assessment of the impact of nanoengineered materials on eco-systems is important and research in this area has also been developed by collaborative projects involving experts in nanotoxicity. The above topics are reviewed here by presenting a brief conceptual framework together with illustrative case studies, in some cases with original research results, mainly focusing on the chemistry of the nanomaterials investigated for target applications. Finally, near-future developments in this research area are put in perspective, forecasting realistic solutions for the application of colloidal nanoparticles in water cleaning technologies.

“…For example, the use of SDS and MWCNT was found to improve recovery of CO 2 from the CO 2 /CH 4 gas mixture compared with that in the pure MWCNT system . Hydrate formation within porous media and stirred tank reactors in the presence of nanofluid was also investigated, − and the results showed that nanofluids can better promote hydrate formation in both porous media and stirred tank reactors.…”

Hydrate-based gas separation is a promising method for CO2 capture from CO2/CH4 gas mixtures, and with improved gas separation efficiency, rate of hydrate formation, and gas uptake, this process has the potential to be taken from the lab scale to industry. In this regard, a significant body of work has been conducted in recent years with the aim to enhance the kinetics of the hydrate-based CO2 capture process. The present study presents a review of the kinetic studies performed on the enhancement of hydrate-based CO2 capture from CO2/CH4 in terms of using additives, porous media, nanofluids, etc. Future research directions are also discussed. The present review aims to aid understanding of the mechanism of the hydrate-based CO2 capture process and to provide references for the development of hydrate-based CO2 capture technology toward industrial applications in the near future.

“…Several studies and reviews have been reported in the literature. Most of these reviews focus on a specific type of KHP and hydrate former. − In this review, the effect of three common types of KHPs (surfactants, amino acids, and nanoparticles) on methane and carbon dioxide hydrates are discussed. This knowledge is helpful in the applications for energy storage and transportation as well as carbon capture.…”

Thermodynamic and Kinetic Promoters for Gas Hydrate Technological Applications

In recent years, there has been growing interest in gas hydrates as technological applications, such as for energy (methane and hydrogen) storage and transportation, separation (gas and desalination), and carbon capture. However, there are several challenges that deter large-scale applications and commercialization of these hydrate-based technologies. One of the main challenges is the long induction time and slow growth of hydrate particles, which can increase the overall operating costs of these technologies. It has been reported that the addition of additives (known as hydrate promoters) can help improve the nucleation and growth rate of hydrates. In general, there are two types of hydrate promoters: thermodynamic hydrate promoters and kinetic hydrate promoters. Thermodynamic hydrate promoters shift the hydrate equilibrium curve to milder conditions (i.e., lower pressures and higher temperatures), while kinetic hydrate promoters reduce the induction time for hydrate formation and increase the growth rate. In this review, we provide a comprehensive review of the two types of hydrate promoters (thermodynamic and kinetic) and their effects on hydrate phase equilibria, induction time, and growth rate.
