Join DVS Vacuum Product Manager, Dr. Vladimir Martis, for this free webinar. In this session, we will explore different aerogel composites and their suitability as heterogeneous catalysts for CO2 Hydration Reaction in both gaseous and aqueous phases.

Beneficial to those working in:

  • Nanomaterials
  • Porous materials


Wavy nickel nanowires (NiNWs) were immobilized on mesoporous silica (SiO2) aerogels by the sol−gel method. The catalytic activity of pure NiNWs and NiNW−SiO2 aerogel composites toward the CO2 hydration reaction (CHR) when they are in water was measured. Dynamic Vapor Sorption (DVS Vacuum) analysis was performed at levels of 50% CO2 and 50% H2O vapor for SiO2 aerogels, immobilized nickel nanoparticles (NiNPs) on silica aerogel and NiNW−SiO2 aerogel composites, in order to determine catalytic activity for CHR in the gaseous phase. The results from DVS Vacuum analysis (gaseous phase) and CHR (aqueous phase) showed that NiNW−SiO2 aerogel composites are good heterogeneous catalysts for CHR in both gaseous and aqueous phases but they are less active than NiNP−SiO2 aerogel composites
