Citric Acid Catalyst-Assisted Bioactive Glass with Hydrogen Peroxide for Bioactivity and Biodegradability Using Sol-Gel Method.

In this study, carbon-free and completely soluble hydrogen peroxide (HO) was utilized in place of conventional surfactants as a pore-forming agent. Citric acid was also used in low concentration for the hydrolysis reaction. A sol-gel method was used to prepare bioactive glass (BG) specimens of HO-untreated BG, 1M, 2M, and 3M HO-treated BGs.
