Carbon-rich macrocycles and carbon nanoribbons as unique optical materials

Abstract

Carbon-rich macrocycles and carbon nanoribbons are considered as the combination of carbon rich molecular materials and supramolecular macrocycle hosts. They can act as unique optical material candidate choices with free...

Solvent Engineering of Oxygen‐Enriched Carbon Dots for Efficient Electrochemical Hydrogen Peroxide Production

“…On account of the significantly improved electrochemical properties of the O-CDs-3 catalyst, it can be a promising candidate as a cathode catalyst in an alkaline fuel cell for electrochemical H 2 O 2 production. [55]…”

Bismacrocycle: Structures and Applications

“…In the past six decades, macrocycles with different structures and properties have emerged. These macrocycles include crown ethers [ 1 , 2 , 3 ], cyclodextrins [ 4 , 5 , 6 ], calixarenes [ 7 , 8 ], cucurbiturates [ 9 , 10 ], and carbon-rich macrocycles [ 11 , 12 , 13 ], etc. They have continuously promoted the development of supramolecular chemistry.…”

Shifting the O2 reduction pathway from H2O to H2O2via in situ reconstruction of Ti2O3 nanoparticles

“…Hydrogen peroxide (H 2 O 2 ) is an environmentally friendly and fundamental oxidizing agent that is widely used in chemical synthesis, pulp bleaching, disinfection, wastewater treatment and energy applications. [1][2][3] Nevertheless, the current industrialscale production of H 2 O 2 relies on the anthraquinone process, which presents drawbacks such as high energy consumption, complex operation, and the generation of signicant amounts of hazardous waste. [3][4][5] The direct synthesis of H 2 O 2 by hydrogen and oxygen poses a huge risk of explosion with undesired yield and selectivity.…”

[3][4][5] The direct synthesis of H 2 O 2 by hydrogen and oxygen poses a huge risk of explosion with undesired yield and selectivity. 6 Renewable-electricity-driven electrochemical processes provide a promising alternative for sustainable H 2 O 2 production via a two-electron oxygen reduction reaction (2e − ORR), ideally consuming only water and oxygen.…”
