biostudies-literatureUnknown4(16)Song LSolar-driven CO₂ conversion into the industrial chemical CO <i>via</i> the reverse water-gas reaction is an ideal technological approach to achieve the key step of carbon neutralization. The high reaction temperature is cost-free due to the photothermal conversion brought about by solar irradiation and is beneficial to the catalytic efficiency. However, the thermostability of adopted catalysts is a great challenge. Herein, we develop an <i>in situ</i> photothermal synthesis to obtain a CuO _<i>x</i> &FeO _<i>y</i> catalyst with a layered double hydroxide-derived pore-confined frame. The optimized sample delivers a CO generation rate of 136.3 mmol min^-1 g_cat ^-1 with the selectivity of ∼100% at a high reaction temperature of 101Nanoscale advances3391-3397https://www.ebi.ac.uk/biostudies/studies/S-EPMC9419767biostudies-literaturePhotothermal synthesis of a CuO _<i>x</i> &FeO _<i>y</i> catalyst with a layered double hydroxide-derived pore-confined frame to achieve photothermal CO₂ hydrogenation to CO with a rate of 136 mmol min^-1 g_cat ^-1.PMC9419767Song LOuyang SYi XYe JfalsePhotothermal synthesis of a CuO _<i>x</i> &FeO _<i>y</i> catalyst with a layered double hydroxide-derived pore-confined frame to achieve photothermal CO₂ hydrogenation to CO with a rate of 136 mmol min^-1 g_cat ^-1.Solar-driven CO₂ conversion into the industrial chemical CO <i>via</i> the reverse water-gas reaction is an ideal technological approach to achieve the key step of carbon neutralization.
