Synthesis of magnesium nanocomposites decked with multilayer graphene (MG) and its application for the adsorptive removal of pollutant

Multifunctional nanocomposites based on graphite-phase carbon nitride quantum dot-silver nanospheres for combined photothermal–photodynamic anti-tumor therapy

“…The introduction of AgNSs does not change the structure of g-CNQDs much. The absorption peak of g-CNQDs is attributed to the stretching vibration of the triazine ring, and the characteristic absorption peaks at 1192, 1401, 1575, and 1704 cm À1 correspond to the telescoping vibration of C-O, C-N, CQN, and CQO, respectively, 26 The broad peaks at 3000-3500 cm À1 are attributed to the telescoping vibration of O-H and N-H. 27 In essence, the formation of a g-CNQDs@AgNSs nanocomposite does not change the original g-CNQD structure much. The elemental composition and chemical structure of g-CNQDs@AgNSs were further studied by XPS as displayed in Fig.…”

Removal of Cr6+ ions and mordant violet 40 dye from liquid media using Pterocladia capillacea red algae derived activated carbon-iron oxides

“…Activated Carbon (AC), is used for different purposes in many industries. It can be defined as substances whose inner surface area and pore volume are increased by physically or chemically activating substances whose composition mostly consists of carbon 44 – 49 . Since activated carbon can adsorb a wide variety of molecules on its inner surface, it is used for the adsorption of various substances in the solid or gas phase 50 .…”

Mg–O–F Nanocomposite Catalysts Defend against Global Warming via the Efficient, Dynamic, and Rapid Capture of CO2 at Different Temperatures under Ambient Pressure

“…Currently, the CO 2 adsorption technique is used on some highly active materials, such as basic metal oxides, to combat global warming. In the pure form or promoted with other materials, MgO is regarded as a cornerstone component in all prepared materials for CO 2 capture purposes, among these basic metal oxides. − This characteristic relates to the abundance and strength of basic sites over the MgO surface. − Other types of adsorbents, including the reduced graphene oxide–MnO 2 nanocomposite, nickel–lithium silicate for CO 2 capture and subsequent production of CH 4 , Li 4 SiO 4 -based sorbents for high-temperature CO 2 capture, NiO-functionalized ultra-stable Y zeolite, Mg–Al mixed metal oxides for high-temperature CO 2 capture, alumina-supported layered double hydroxides, CuAl 2 O 4 nanoplates, Ni–CaO dual function materials, and CaO–Fe 2 O 3 –SiO 2 composite, have been extensively examined . Few articles have focused on the study of capturing CO 2 in a dynamic mode at different temperatures by flowing CO 2 gas at different rates through the adsorbents. , Many review articles with a forward-looking perspective discussed various CO 2 capture techniques − utilizing different adsorbent materials.…”
