Koh activation of carbon based materials for energy storage
KOH Chemical-Activated Porous Carbon Sponges for Monolithic
Developing monolithic electrodes with high capacitor performance remains a challenge in energy storage field. KOH is applied to chemically activated commercial melamine sponges, and it can prepare monolithic N-/O-doped carbon sponge (NOCS) electrodes.
KOH activation of carbon-based materials for energy storage
Moreover, KOH activation is also efficient for generating micropores and small mesopores into the framework of various structured carbons, such as carbon fibers (CFs), carbon nanofibers (CNFs), CNTs, templated porous carbons (TPCs), carbide-derived carbons (CDCs), carbon aerogels (CAs), and graphene.
KOH activation of carbon-based materials for energy storage
In this feature article, we will cover recent research progress since 2007 on the synthesis of KOH-activated carbons for hydrogen and electrical energy storage (supercapacitors and lithium–sulfur batteries).
Insight into KOH activation mechanism during biomass pyrolysis
In this study, the effects of KOH/biomass ratios (1:8 to 1:1) and temperatures (400–800 °C) on biomass pyrolysis were investigated. The KOH chemical activation mechanism was explored by revealing the evolution mechanisms of the gaseous product, bio-oil, biochar, and KOH, based on experiments and quantum calculations.
