Carbon-incorporated Fe3O4 nanoflakes: high-performance faradaic materials for hybrid capacitive deionization and supercapacitors

“…With an energy density of 32.5 W h kg À1 at a power density of 400 W kg À1 , our hybrid supercapacitor exhibits performances comparable to those of previous Fe 3 O 4 -based hybrid supercapacitors, such as Ni(OH) 2 //F2RF-150 (4.1 W h kg À1 , 661.5 W kg À1 ), 41 MnHCF//Fe 3 O 4 /rGO (27.9 W h kg À1 , 2183.5 W kg À1 ), 42 CPY//C-G/AFC (18.3 W h kg À1 , 351 W kg À1 ), 12 and Fe 3 O 4 @Fe 2 O 3 //Fe 3 O 4 @MnO 2 (26.6 W h kg À1 , 500 W kg À1 ). 43 With the worsening of the energy and environmental issues, [44][45][46][47] the exploration of new-class water treatments that save energy and are environmentally friendly has taken on new urgency. In this regard, CDI has been developed based on electrical double layer theory and has received increasing interest over the past decade.…”

Graphene–carbon 2D heterostructures with hierarchically-porous P,N-doped layered architecture for capacitive deionization

“…With an increasing world population, worsening environment, and climate and energy crises, [1][2][3][4] the economical supply of clean, potable water is rapidly becoming a critical issue for human subsistence. In this regard, capacitive deionization (CDI), an advanced electrochemical deionization technology, has emerged as a competitive methodology for the desalination of brackish water and seawater, due to its several important advantages including low energy consumption, cost effectiveness, and environmental benignity.…”

An efficient CuO/rGO/TiO2photocatalyst for the synthesis of benzopyranopyrimidine compounds under visible light irradiation

“…For example, the synthesis of 1,4-disubstituted 1,2,3-triazoles using a Cu 2 O/reduced graphene oxide/TiO 2 photocatalyst under visible light, 15 the coupling of nitroaromatic compounds by Cu NPs on a graphene support, 16 the coupling reaction of phenol and alkynes under visible light in the presence of copper, 17 and the synthesis of 2-amino-4,6-diarylpyrimidines using titanium dioxide (TiO 2 ) as the photocatalyst under ultraviolet (UV) irradiation 18 have been investigated. The approved photocatalytic activity of a wide range of metal and metal oxide nanoparticles, 19–21 especially TiO 2 with low-cost, non-toxicity and ultraviolet active properties, 22 has led to their wide applications. The importance of applying visible light, owing to its higher share (45%) in comparison with UV light (5%), 23 justifies the modification of the activity range of TiO 2 .…”
