Synthesis of Ordered Mesoporous Carbon Materials by Dry Etching [PDF]

open access: yesChemistry – A European Journal, 2015
AbstractA novel synthesis method for ordered mesoporous carbons is presented. The inverse replication of a silica template was achieved using the carbonization of sucrose within mesoporous KIT‐6. Instead of liquid acid etching, as in classical nanocasting, a novel dry chlorine etching procedure for template removal is presented for the first time.

Accelerated Synthesis of Ordered Mesoporous Carbons Using Plasma

open access: yesACS Omega, 2023
Conventional ordered mesoporous carbon (OMC) production usually requires long processing times in the carbonization step to achieve desired temperatures through controlled ramps. To enable expedited materials discovery, developing advanced manufacturing capability with significantly improved throughput is highly desired.
