Synthesis and Characterization CO۲ sensor based on sio۲ nanoparticle

Generally, chromism is a compound that by external stimuli could change its color reversibly. Here, a nanoparticle sensitive to CO۲ gas and pH is synthesized. which is easily dispersed in water. By blowing gas ۱, a color change is created in the solution, which indicates a change in pH. Response to this stimulus was assessed by UV-vis spectroscopy. The identification of these nanoparticles was also carried out by FT-IR and SEM.
