Excellent CO 2 conversion : The cover image demonstrates a photocatalytic reactor with a thin film of layered double hydroxide (LDH) inside it. The reaction gas pressure was 0.40 MPa and CO 2 reduction was tested using H 2 and an LDH photocatalyst comprising zinc, gallium, and/or copper. In view of the application, H 2 is sustainably formed from water. This study enables a carbon‐neutral cycle to convert CO 2 into fuels (methanol and/or methane) avoiding the net increase in atmospheric CO 2 concentrations associated with fossil‐derived alternatives. If the LDH catalysts were used after the exposure to air, the CO 2 was photoconverted into methanol. In contrast, if the catalysts were preheated at 423 K and protected in argon gas, methane (using LDH comprising Zn and Ga) and methanol (using LDH comprising Zn, Cu, and Ga) were produced up to the formation rate of 2.7 μmol h −1 g cat −1 .
