TL;DR: Based on the sorption behaviors and the characteristics of the adsorbents and adsorbates, ion exchange and electrostatic interaction as well as hydrophobic interaction were deduced to be involved in the sor adaptation, and some hemi-micelles and micelles possibly formed in the intraparticle pores.

TL;DR: In this paper , the progress in the development of each category of catalysts is summarized, current status is reviewed, the remaining challenges are pointed out, and the future research directions are prospected, with the aim being to pave pathways for the rational design of better catalysts.
Abstract: Photo-catalytically converting the greenhouse gas CO2 into ethanol is an important avenue for the mitigation of climate issues and the utilization of renewable energies. Catalysts play critical roles in the reaction of photocatalytic CO2 conversion to ethanol, and a number of catalysts have been investigated, including semiconductors and plasmonic metal-based catalysts, as well as several other catalysts. In this review, the progress in the development of each category of catalysts is summarized, the current status is reviewed, the remaining challenges are pointed out, and the future research directions are prospected, with the aim being to pave pathways for the rational design of better catalysts.

TL;DR: Recommendations for how to proceed with research and cooperation to tackle the vast number of PFASs on the market and in the environment are provided.
Abstract: More than 3000 per- and polyfluoroalkyl substances (PFASs) are, or have been, on the global market, yet most research and regulation continues to focus on a limited selection of rather well-known long-chain PFASs, particularly perfluorooctanesulfonate (PFOS), perfluorooctanoic acid (PFOA) and their precursors. Continuing to overlook the vast majority of other PFASs is a major concern for society. We provide recommendations for how to proceed with research and cooperation to tackle the vast number of PFASs on the market and in the environment.

TL;DR: This review paper would be helpful for the preparation of effective adsorbents for PFC removal and understanding interfacial process of PFCs during their transport and fate in aquatic environments.
631 citations
TL;DR: Early observations suggest that activated carbon adsorption, ion exchange, and high pressure membrane filtration may be effective in controlling these contaminants, however, branched isomers and the increasingly used shorter chain PFAS replacement products may be problematic as it pertains to the accurate assessment of PFAS behaviour through drinking water treatment processes.
576 citations
TL;DR: Irrespective of the dissipation kinetics, the majority of PFOA and PFOS from contaminated soils will be transported to groundwater and surface water bodies and applying lab-based log K(oc) distribution coefficients can result in a serious overestimation of PFC concentrations in water and in turn to an underestimation of the residence time of PFLs in contaminated soils.
447 citations
TL;DR: A critical review of the recent peer-reviewed studies on the removal of long- and short-chain PFAS by adsorption is provided to review the performance of different adsorbents for both long-and-short-chainPFAS, the effect of organic matter, and the adsorbent regeneration techniques.
