The oxygen reduction reaction (ORR) is one of the key steps in clean and efficient energy
conversion techniques such as in fuel cells and metal–air batteries; however, several …

Transition-metal-and nitrogen-codoped carbide-derived carbon/carbon nanotube
composites (MN-CDC/CNT) have been prepared, characterized, and used as cathode …

Abstract Two-dimensional (2D) mesoporous materials (2DMMs), defined as 2D nanosheets
with randomly dispersed or orderly aligned mesopores of 2–50 nm, can synergistically …

Carbon quantum dots (C-Dots) have drawn extensive attention in recent years due to their
stable physicochemical and photochemical properties. However, the development of …

A zeolitic‐imidazolate‐framework (ZIF) nanocrystal layer‐protected carbonization route is
developed to prepare N‐doped nanoporous carbon/graphene nano‐sandwiches. The …

Electrochemical reduction of oxygen molecules can produce H2O2, which is an important
chemical for a green and sustainable society; therefore, the development of catalysts for this …

Rational design a metal-free catalyst with well-defined structure as alternative of noble metal
