Abstract Subnanometer pores of carbon discriminate against ions based on their size. Capitalizing on such nuanced differences enables ion separation via charge/discharge cycling during ion electrosorption. Different ion uptake capacities in aqueous media with multiple, competing ions are also of high importance to understand capacitive deionization of surface water or industrial process water. In our experiments, we observed divalent cations sieving in pores smaller than 0.6 nm. By applying this...

Abstract Thermal safety concerns of lithium ion batteries (LIBs) need to be solved urgently to facilitate their large-scale applications. Introducing safer anode materials can suppress the thermal runaway initiation but is usually compromising the cell performance due to their induced lower energy density. In this work, Ti3C2Tz MXene with tailored surface terminating groups is identified to be a safer LIB anode with improved capacity and lower operational potential. Calorimetric analyses demonst...

Abstract Photocatalytic CO2 reduction is one of the most promising ways to solve the energy crisis and the greenhouse effect. However, it is very difficult to reduce CO2 with 8 electrons to form CH4. Monolayer layered double hydroxides (denote as LDHs) have drawn wide attention and interest due to the abundant defects and unique electronic structure. However, the monolayer LDHs can be obtained mainly in the lab scale, which seriously hindered their practical large-scale industrial application. H...

Abstract This paper details an investigation into the separation of Hexamethylenediamine (HMD) from dilute aqueous solutions by exploiting phase separation. HMD is a monomer used in the production of Nylon-6,6 and as such this separation is potentially useful in extracting purifying HMD produced from biological sources or reclaimed from waste made by the production of nylon. An investigation was undertaken into the effect of using sodium hydroxide (NaOH) to promote the phase separation, and a mo...

Abstract Separation of chemicals using membranes in smaller size regimes is a much-complicated process. An ideal membrane for molecular separation should be more hydrophilic with well-defined pore sizes for ensuring the selectivity to give a maximum solvent flux. Here, we report a poly(itaconic acid-co-styrene-co-sulfobetaine vinylimidazole) (PIL)/PSf blend selective filtration membrane with nanochannels for superior molecular separation. FESEM images showed asymmetrical membrane structure with ...

Abstract The design and development of advanced functional materials for efficient absorption and selective conversion of carbon dioxide (CO2) remains a challenging research topic. In this work, novel cyclotriphosphazene-based periodic mesoporous organosilicas (PMO-CPF) with various contents of active components and tunable porosity were successfully prepared via direct co-condensation method, and their structures were characterized by FT-IR, solid-state 13C, 29Si and 31P NMR, XRD, N2 adsorption...

Abstract Using solar energy instead of traditional steam energy could be a promising strategy for saving the CO2 capture energy consumption. Here we report solar triggered efficient CO2 release from a mussel-inspired CO2 capture solvent. Crosslinking polyethyleneimine and polydopamine by the self-polymerization was applied to capture CO2 and efficiently release CO2 by photoirradiation. CO2 absorption rate was improved by increasing the dopamine content in the crosslinked polymer. Furthermore, CO...

Abstract Recently, advanced oxidation processes (AOPs) combined with membrane filtration as highly active catalytic self-cleaning membrane to decrease energy and cost consumption has attracted considerable attention in environmental remediation. In this study, a kind of novel 2D bimetallic sulfides/N-doped reduced graphene oxide (FeCoS@N-rGO) composite was firstly developed via the self-assembly of MOFs and GO nanosheets followed by carbonization and further sulfuration, subsequently 2D/2D catal...
