Preparation and characterization of hollow glass microspheres (HGMs) for hydrogen storage using urea as a blowing agent
HGMs with and without urea were synthesized using flame spheroidization. Effect of urea concentration on HGMs for hydrogen adsorption was investigated. The blowing agent like urea loading in HGMs results in enhanced hydrogen storage capacity. The hydrogen storage capacity was found to be 2.3wt.% on HAU2, whereas on HA it was only 1.23wt.%.
