Abstract
A method for preparing a nano-enabled activated carbon block, a nano-enabled activated carbon block produced by the method, a household water filtration system comprising the nano-enabled activated carbon block, and a method for filtering tap water using the household water filtration system are provided. The method includes contacting a solution including a metal(lic) precursor (e.g. a titanium compound and/or an iron compound and/or a zirconium compound) with activated carbon particles such that the solution fills pores of the activated carbon particles. The method further includes causing a metal (hydr)oxide (e.g. titanium dioxide and/or zirconium dioxide and/or iron oxide) to precipitate from the solution thereby causing metal oxide nanoparticles to become deposited within pores of the activated carbon particles. The method also includes preparing a nano-enabled activated carbon block from the activated carbon particles having metal oxide nanoparticles deposited within the pores thereof.
