Oxygen-containing carbons are promising supports and metal-free catalysts for many reactions. However, distinguishing the role of various oxygen functional groups and quantifying and tuning each functionality is
The mutual constraint relationship between high specific capacity and excellent conductivity caused by the content of oxygen-containing functional groups is also pointed out. Carbon materials with rich oxygen are expected to be developed in lithium/sodium-ion batteries, fuel cells, electrocatalysis, ...

Esters have a pair of alkyl or aromatic groups attached to a carbonyl + linking oxygen function. Esters can be shown in text as: RCOOR or (occasionally) ROCOR. carboxylic acid + alcohol -> ester + water This is an acid catalysed equilibrium. Amide Primary amides (shown) have an alkyl or...
Chemical transformations that introduce, remove or manipulate functional groups are ubiquitous in synthetic chemistry1. Unlike conventional functional-group interconversion reactions that swap one functionality for another, transformations that alter sol
It is usually a compound with silicon-oxygen (Si-O) bonds in the main chain and organic groups as the side chains. It offers many advantages as a TIM because of its excellent elasticity, aging resistance, low toxicity, oxidation resistance, low water absorption, electrical-insulating properties...
