A series of carbon molecular sieves (CMSs) has been prepared, either as powders or monoliths, from petroleum pitch using potassium hydroxide the activating agent. The CMS monoliths are prepared without use a binder based on self-sintering ability mesophase pitch. Characterization results show that these CMSs combine large apparent surface area (up to ca. 3100 m(2) g(-1)) together with well-developed narrow microporosity (V(n) up 1.4 cm(3) g(-1)). materials exhibit high adsorption capacities...
Abstract Widespread access to greener energy is required in order mitigate the effects of climate change. A significant barrier cleaner natural gas usage lies safety/efficiency limitations storage technology. Despite highly porous metal-organic frameworks (MOFs) demonstrating record-breaking gas-storage capacities, their conventionally powdered morphology renders them non-viable. Traditional powder shaping utilising high pressure or chemical binders collapses porosity creates low-density...
Natural methane hydrates are believed to be the largest source of hydrocarbons on Earth. These structures formed in specific locations such as deep-sea sediments and permafrost based demanding conditions high pressure low temperature. Here we report that, by taking advantage confinement effects nanopore space, synthetic grow under mild (3.5 MPa 2 °C), with faster kinetics (within minutes) than nature, fully reversibly a nominal stoichiometry that mimics nature. The formation hydrate...
Natural gas storage on porous materials (ANG) is a promising alternative to conventional on-board compressed (CNG) or liquefied natural (LNG). To date, Metal–organic framework (MOF) have apparently been the only system published in literature that able reach new Department of Energy (DOE) value 263 cm3 (STP: 273.15 K, 1 atm)/cm3; however, this was obtained by using ideal single-crystal density calculate volumetric capacity. Here, we prove experimentally, and for first time, properly designed...
In this work, we have fabricated an aryl amino-substituted graphitic carbon nitride (g-C3N4) catalyst with atomically dispersed Mn capable of generating hydrogen peroxide (H2O2) directly from seawater. This new exhibited excellent reactivity, obtaining up to 2230 μM H2O2 in 7 h alkaline water and 1800 seawater under identical conditions. More importantly, the was quickly recovered for subsequent reuse without appreciable loss performance. Interestingly, unlike usual two-electron oxygen...
We are currently witnessing the dawn of hydrogen (H2) economy, where H2 will soon become a primary fuel for heating, transportation, and long-distance long-term energy storage. Among diverse possibilities, can be stored as pressurized gas, cryogenic liquid, or solid via adsorption onto porous materials. Metal–organic frameworks (MOFs) have emerged adsorbent materials with highest theoretical storage densities on both volumetric gravimetric basis. However, critical bottleneck use...
Although metal–organic framework (MOF) materials have been postulated as superior to any other sorbent for CO2 adsorption at room temperature, here we prove that the appropriate selection of raw material and synthesis conditions allows preparation carbon molecular sieves (CMSs) with capacity, on a volumetric basis, highly exceeding those reported in literature MOFs. Furthermore, excellent sorption properties CMSs over whole pressure range (up 50 bar) are fully reversible after different...
Mitochondria play a key role in oncogenesis and constitute one of the most important targets for cancer treatments. Although effective way to deliver drugs mitochondria is by covalently linking them lipophilic cation, vivo delivery free still constitutes critical bottleneck. Herein, we report design mitochondria-targeted metal-organic framework (MOF) that greatly increases efficacy model drug, reducing required dose less than 1% compared drug ca. 10% nontargeted MOF. The performance system...
The effect of surface chemistry (nature and amount oxygen groups) in the removal ammonia was studied using a modified resin-based activated carbon. NH3 breakthrough column experiments show that modification original carbon with nitric acid, is, incorporation groups, highly improves adsorption behavior at room temperature. Apparently, there is linear relationship between total capacity more acidic less stable groups. Similar moist air clearly humidity depends on used. Moisture for samples low...
The formation of methane hydrates on MOFs has been identified for the first time using inelastic neutron scattering and synchrotron X-ray powder diffraction.
The gate-opening phenomenon in ZIFs is of paramount importance to understand their behavior industrial molecular separations. Here we show for the first time using situ inelastic neutron scattering (INS) swinging -CH3 groups and imidazolate linkers prototypical ZIF-8 ZIF-8@AC hybrid materials upon exposure mild N2 pressure.

At the mesoscale, structure into interconnected close‐packed clusters few microns in extent, thus facilitating fabrication dense crack‐free areal sulfur loading (5 mg cm −2 ) cathodes with electrical conductivity low impedance. A combination nitrogen...
Novel MOF-based polymer nanocomposite films were successfully prepared using Zr-based UiO-67 as a metal-organic framework (MOF) and polyurethane (PU) polymeric matrix. Synchrotron X-ray powder diffraction (SXRPD) analysis confirms the improved stability of embedded nanocrystals scanning electron microscopy images confirm their homogeneous distribution (average crystal size ~100-200 nm) within 50-um thick film. Accessibility to inner porous structure MOFs was completely suppressed for N2 at...
Metal–organic frameworks (MOFs) have been evaluated as potential nanocarriers for intraocular incorporation of brimonidine tartrate to treat chronic glaucoma. Experimental results show that UiO-67 and MIL-100 (Fe) exhibit the highest loading capacity with values up 50–60 wt %, whereas performance is quite limited MOFs narrow cavities (below 0.8 nm, example, UiO-66 HKUST-1). The large in accompanied by an irreversible structural amorphization aqueous physiological media promotes extended...
Porous metal-organic frameworks (MOFs) capable of storing a relatively high amount dry methane (CH4) in the adsorbed phase are largely explored; however, solid CH4 storage confined pores MOFs form hydrates is yet to be discovered. Here we report rational approach by taking advantage optimal pore confinement narrow cavities hydrolytically stable MOFs. Unprecedentedly, were able isolate hydrate (MH) nanocrystals with an sI structure encapsulated inside MOF cavity dimension. It was found that...
Covalent organic frameworks (COFs) have emerged as a versatile material platform for such applications chemical separations, reaction engineering, and energy storage. Their inherently low mechanical stability, however, frequently renders existing methods of pelletization ineffective, contributing to pore collapse, blockage, or insufficient densification crystallites. Here, we present process the shaping densifying COFs into robust centimeter-scale porous monoliths without need templates,...
Space cooling and heating, ventilation, air conditioning (HVAC) accounts for roughly 10% of global electricity use are responsible ca. 1.13 gigatonnes CO2 emissions annually. Adsorbent-based HVAC technologies have long been touted as an energy-efficient alternative to traditional refrigeration systems. However, thus far, no suitable adsorbents developed which overcome the drawbacks associated with sorbent materials such silica gels zeolites. Metal-organic frameworks (MOFs) offer...

Safe storage and utilisation of hydrogen is an ongoing area research, showing potential to enable becoming effective fuel, substituting current carbon-based sources. Hydrogen associated with a high energy cost due its low density boiling point, which drives price. Clathrates (gas hydrates) are water-based (ice-like) structures incorporating small non-polar compounds such as H
