Metal-free heteroatom-doped carbocatalysts with a high surface area are desirable for catalytic reactions. In this study, we found an efficient strategy to prepare nitrogen, phosphorus, and sulfur co-doped hollow carbon shells (denote as NPS-HCS) of 1020 m(2) g(-1). Using poly(cyclotriphosphazene-co-4,4'-sulfonyldiphenol) (PZS) shell source N, P, S-doping source, the ZIF-67 core structural template well extra N-doping NPS-HCS were obtained superhydrophilicity.

With the ever-increasing production of electronics, there is an ensuing need for gold extraction from sources other than virgin mines. Currently, are no technologies reported to date that can effectively and selectively concentrate ultratrace amounts liquid sources.

Metal-organic frameworks (MOFs) offer great promise in a variety of gas- and liquid-phase separations. However, the excellent performance on lab scale hardly translates into pilot- or industrial-scale applications due to microcrystalline nature MOFs. Therefore, structuring MOFs pellets beads is highly solicited timely requirement. In this work, general method developed for preparing MOF-polymer composite based an easy polymerization strategy. This adopts biocompatible, biodegradable...
In this contribution, recent advances in the construction of MOF-polymer composites and their corresponding applications are briefly reviewed. The appearance such architectures is becoming prominent literature, due to fact that union these two dissimilar components can give rise a number desirable properties not necessarily achieved by individual components. For instance, while MOFs already boast unprecedented internal surface areas highly tunable pore structures, they often suffer from...
Metal-organic frameworks are of interest in a number host-guest applications. However, their weak coordination bonding often leads to instability aqueous environments, particularly at extreme pH, and hence, is challenging topic the field. In this work, two-step, post-synthetic polymerization method used create series highly hydrophobic, stable MOF composites. The MOFs first coated with thin layers polydopamine from free-base dopamine under mild oxygen atmosphere, which then undergoes Michael...
Abstract Electrocatalytic reduction of carbon monoxide into fuels or chemicals with two more carbons is very attractive due to their high energy density and economic value.

With the fast-growing accumulation of electronic waste and rising demand for rare metals, it is compelling to develop technologies that can promotionally recover targeted like gold, from waste, a process referred as urban mining. Thus, there increasing interest in design materials achieve rapid, selective gold capture while maintaining high adsorption capacity, especially complex aqueous-based matrices. Here, highly porous metal-organic framework (MOF)–polymer composite, BUT-33–poly( para...
Enzymes are natural catalysts for a wide range of metabolic chemical transformations, including selective hydrolysis, oxidation, and phosphorylation.
