CO2 emissions into the atmosphere account for the majority of environmental challenges and its global impact in the form of climate change is well-documented. Accordingly, the development of new materials approaches to capture and convert CO2 into value-added products is essential. Whereas the increased availability of renewable energy is curbing our reliance on fossil fuels and decreasing...

Although being incorporated in commercial lithium‐ion batteries for a while, the weight portion of silicon monoxide (SiOx, x ≈ 1) is only less than 10 wt% due to the insufficient cycle life. Along this line, polymeric binders that can assist in maintaining the mechanical integrity and interfacial stability of SiOx electrodes are desired to realize higher contents of SiOx. Herein, a...

Desiccant driven dehumidification for maintaining the proper humidity levels and atmospheric water capture with minimum energy penalty are important aspects in heat pumps, refrigeration, gas and liquid purifications, gas sensing, and clean water production for improved human health and comfort. Water adsorption by using nanoporous materials has emerged as a viable alternative to...

Despite their unparalleled theoretical capacity, lithium‐metal anodes suffer from well‐ known indiscriminate dendrite growth and parasitic surface reactions. Conductive scaffolds with lithium uptake capacity are recently highlighted as promising lithium hosts, and carbon nanotubes (CNTs) are an ideal candidate for this purpose because of their capability of percolating a conductive...

The quest for new electrode materials for Li-ion batteries with high energy densities beyond conventional intercalation-based electrodes has gained significant attention due to the increasing demand for advanced portable devices and electric vehicles (EVs). Among various candidates, the most promising electrode materials along this direction are silicon and Li metal for anodes and sulfur for...

We demonstrated that the ratio and position of two different metal ions, Pd and Cu, can be precisely controlled within MOFs through predesigned metal clusters. These MOF structures incorporating Pd–Cu paddle wheel units were synthesised simply by reacting Pd–Cu acetate metal clusters and tritopic organic linkers at room temperature. Pd–Cu open metal sites were found to be uniformly...

Conjugated microporous polymers (CMPs) offer a unique structure integrating π- conjugated backbone into a porous network for the simultaneous transport of charges and materials. However, tuning electronic properties of CMPs so far has been limited to an approach of varying the monomers, and the precious metal catalysts are inevitably needed for the C–C coupling reaction. Here, we present a...

Silicon (Si) anode is among the most promising candidates for the next-generation high-capacity electrodes in Li-ion batteries owing to its unparalleled theoretical capacity (4200 mA h g−1 for Li4.4Si) that is approximately 10 times higher than that of commercialized graphitic anodes (372 mA h g−1 for LiC6). The battery community has witnessed substantial advances in research on new...

We report on the synthesis of highly microporous, epoxy-functionalized porous organic polymers (ep-POPs) through one pot, catalyst-free Diels-Alder cycloaddition polymerization. The high oxygen content of ep-POPs offered efficient hydrogen bonding sites for water molecules, thus leading to high water uptake capacities, up to 39.2-42.4%, under a wide temperature range of 5-45oC, covering the...

In order to address the challenges associated with lithium–sulfur batteries with high energy densities, various approaches, including advanced designs of sulfur composites, electrolyte engineering, and functional separators, are lately introduced. However, most approaches are effective for sulfur cathodes with limited sulfur contents, i.e., <80 wt%, imposing a significant barrier in...
