Empowering Sustainable Energy-Water-Environment Nexus: Green Promoters for Rapid Methane Hydrate Formation
International audience Synthetic gas hydrates is a novel nanoporous material for many energy transition applications but its applicability is hindered by the slow formation kinetics. Our group explored environmentally-friendly kinetic hydrate promoters (KHPs) , like acidic/basic zeolites and amino a...
