Although one can create uranium oxide using different methodology, this paper confirms sol gel synthesis can produce U3O8/SiO2 nanocomposites. Based on the above data, one can conclude using standard conditions with the absence of hydrochloric acid and acetic acid as catalysis present can produce homogeneous nanocomposites. One can use this cheap and costeffective synthesis method and add to further application ideas on soil, water and or bacteria for further studies.
