Highly dispersed Pt species anchored onto NH₂-Ce-MOFs and their derived mesoporous catalysts for CO oxidation

Abstract

Simultaneously maximizing the dispersion of noble metals and demonstrating optimal activity is of significant importance for designing stable metal catalysts. In this study, highly dispersed ultrafine platinum (Pt) particles with...

An electrochemical sensor for sensitive detection of dopamine based on a COF/Pt/MWCNT–COOH nanocomposite

“…Then, Pt nanoparticles were anchored on the surface of the COF by the coordination of Pt with -NH. 33 The TEM image of COF/Pt (Fig. 1C, ESI †) clearly proved the existence of Pt nanoparticles on the COF.…”

CuIr Nanoparticles for Electrochemical Reduction of CO2 to t‐BuOH

“…On the other hand, the XRD patterns of Ir NPs were very broad due to their small size (≈1.6 nm) and/or low crystallinity. [ 30 ] The alloy formation is further confirmed by the UV−Vis absorption spectra of the Cu, Cu 0.72 Ir 0.28 , Cu 0.48 Ir 0.52 , and Ir NPs in Figure S7 (Supporting Information). Here, the characteristic absorption peaks of Cu (583 nm) and Ir (304 nm) are observed in pure Cu and Ir samples, respectively, while the Cu 0.72 Ir 0.28 and Cu 0.48 Ir 0.52 NPs exhibit a single absorption peak at 476 and 430 nm, respectively.…”

Investigation of Hydroxyapatite-Entrenched Cerium Organic Frameworks Incorporating Biopolymeric Beads for Efficient Fluoride Removal

“…Figure b). Besides, the stretching vibrations of Ce–O were observed as a low intensity band from 400 to 800 cm –1 . The −OH group of the developed HAp-loaded Ce-MOFs material was noted at 3400 cm –1 .…”
