Metal—organic frameworks MOFs and zeolitic imidazolate frameworks ZIFs are promising porous materials for adsorption and storage of greenhouse gases, especially CO 2. In this study, guided by the CO 2 phase diagram, we explore the adsorption behavior of solid CO 2 loaded with ZIF-8 framework by heating the sample under high pressures, resulting in a drastic improvement in the CO 2 uptake.

Metal-organic framework MOF membranes are potentially useful in gas separation applications, but conventional methods for preparing MOF membranes are multi-steps and under high-pressure synthetic conditions. The enhanced separation performance obtained in this study has been the highest so far among other supported pure ZIF-8 membranes, which can be attributed to the defect-free and thermally stable ZIF-8 membranes.

China E-mail: chunshengwu ZIF-8 nanoparticles were prepared with a convenient method at room temperature. The ZIF-8 nanoparticles were relatively stable under neutral and alkaline solutions, while their structure easily collapsed partially in the strong acidic aqueous solution. The adsorption kinetics and isotherms of ZIF-8 for tetracycline were evaluated in detail. The effects of key parameters such as pH, contact time, temperature and ionic strength on the adsorption of tetracycline were studied. The data on the adsorption of tetracycline on the ZIF-8 nanoparticles fitted well to the pseudo-second-order kinetics model, while the adsorption isotherm data can be explained respectively by the Langmuir isothermal model and the Freundlich isotherm model to varying degrees.

The use of nanomaterials for the controlled release of drugs aims to enhance their effectiveness, especially when poorly soluble in water, and achieve their rapid, localized, and effective administration. The present study focuses on the use of a Zeolitic Imidazolate Framework-8 ZIF-8 as vehicle for the transport and controlled release of the antibiotic ciprofloxacin CIP as model due to its favorable physicochemical characteristics.

As a new kind of porous material, zeolitic imidazolate frameworks ZIF-8 are built from zinc ions and 2-methylimidazolate and possess unique merits including high porosity, good structural regularity and tunability, adjustable surface functionality and intrinsic pH induced biodegradability. These advantages endow ZIF-8 with multiple functionalities and stimuli-responsive controlled release of loaded payloads by endogenous or exogenous means. In this review, we will summarize the recent advancement of ZIF-8 as nanocarriers for the loading of various molecules including chemotherapeutic drugs, photosensitizers, photothermal agents, and proteins to fabricate multifunctional nanocomposites for synergistic cancer therapy. In addition, the challenges and future developments in this area will be highlighted.
