Carbon monoxide may then flow over a fixed-bed reactor loaded with the copper oxide-titanium dioxide nanocatalyst at a temperature between 80 C. and 200 C.

Methods for forming two-dimensional (2D) zeolite nanosheets include exposing a multi-lamellar (ML) zeolite material including an organic structure directing agent (OSDA) to a mixture including sulfuric acid and hydrogen peroxide under conditions sufficient to remove substantially all of the OSDA from the ML zeolite material; and after exposing the ML zeolite material, treating a solution containing the ML zeolite material to sonication and/or mixing under conditions sufficient to substantially exfoliate layers of the ML zeolite to obtain porous two-dimensional zeolite nanosheets that are substantially free of the OSDA.
