Confirmed by DFT, a significant amount of platinum atoms are chemically bound to N N-doped RGO.
Metal-organic frameworks (MOFs) were successfully synthesized by ultrasonic wave-assisted ball milling. In the absence of organic solvent, coupling effect wave and mechanical force played an significant role in synthesis MOFs. Adsorption Congo red (CR) was studied view adsorption kinetic, isotherm thermodynamics.

A metal organic framework (MOF), synthesized from cobalt salt, melamine (mela), and 1,4-dicarboxybezene (BDC), was used as precursor to prepare Co/CoNx/N-CNT/C electrocatalyst via heat treatment at different temperature (700-900 °C) under nitrogen atmosphere. Crystallites size microstrain in the 800 °C heat-treated sample (MOFs-800) were lowest, whereas stacking fault value highest among rest of homemade samples, attested by Williamson-Hall analysis, hence assessing that structural or/and...
Reactions in water between the sodium salt of benzene-1,2,4,5-tetracarboxylic acid (H4btec) and lanthanide ions (Sm–Dy) led to a series isostructural lanthanide-based coordination polymers with general chemical formula [Ln4(btec)3(H2O)12·20H2O]∞ Ln = Sm–Dy. The family has been structurally characterized. From luminescent point view, heterodinuclear strategy successfully applied allows significant brightness enhancement (+35%) color tuning from green yellow orange red.
ZnFe2O4 (ZFO) spinel magnetic nanoparticles with a small particle size (11.2 nm) and large specific surface area (54.1 m2/g) are synthesized by one-step hydrothermal method without the calcination process. ZFO-modified electrodes first utilized for simultaneous electrochemical trace detection of Hg(II), Pb(II), Cu(II), which show an outstanding linear response limit (LOD) is 1.61, 7.38, 12.03 nM, respectively. Meanwhile, exhibit excellent repeatability [relative standard deviation (RSD)...
Metal-organic frameworks (MOFs) are considered potential electrocatalysts for efficient water splitting. However, the structure-activity relationship of most MOFs is not systematically analyzed electrocatalysis anodes and cathodes.
