Title: Methods for making graphene-supported metal oxide monolith

Abstract

Provided here is a method for making a graphene-supported metal oxide monolith, comprising: providing a graphene aerogel monolith; immersing said graphene aerogel monolith in a solution comprising at least one metal salt to form a mixture; curing said mixture to obtain a gel; optionally, heating said gel to obtain a graphene-supported metal oxide monolith.
