The hydrogen required for CO\n            <jats:sub>2<\/jats:sub>\n            hydrogenation can be provided by H radicals formed during aromatization. In this study, we efficiently convert PE and CO\n            <jats:sub>2<\/jats:sub>\n            into aromatics and CO using a zeolite\u2013metal oxide catalyst (HZSM-5 + CuZnZrO\n            <jats:italic>\n              <jats:sub>x<\/jats:sub>\n            <\/jats:italic>\n            ) at 380\u00b0C and under hydrogen- and solvent-free reaction conditions. Hydrogen, derived from the aromatization of PE over HZSM-5, diffuses through the Br\u00f8nsted acidic sites of the zeolite to the adjacent CuZnZrO\n            <jats:italic>\n              <jats:sub>x<\/jats:sub>\n            <\/jats:italic>\n            , where it is captured in situ by CO\n            <jats:sub>2<\/jats:sub>\n            to produce bicarbonate and further hydrogenated to CO. This favors aromatization while inhibiting hydrogenation and secondary hydrogenolysis reactions. An aromatic yield of 62.5 wt % is achieved, of which 60% consisted of benzene, toluene, and xylene (BTX). The conversion of CO\n            <jats:sub>2<\/jats:sub>\n            reaches values as high as 0.55 mmol g\n            <jats:sub>PE<\/jats:sub>\n            <jats:sup>\u22121<\/jats:sup>\n            .
