N1 - Funding Information:
This work was supported by NEDO, JST PRESTO (No. JPMJPR1514) and a Grant‐in‐Aid for Scientific Research (B) (No. 17750056) from JSPS. The synchrotron radiation experiments were performed at the BL02B2 and BL14B2 lines of SPring‐8 with the approval of JASRI (Proposal No. 2018B1501, 2018B1728, 2019A1232 and 2019B1468). We are thankful to Dr. T. Honma of JASRI for technical support during the collection of X‐ray adsorption spectra. The STEM observations were partly supported by the Advanced Characterization Platform of the Nanotechnology Platform Japan (JPMXP09‐A‐19‐KU‐0292) sponsored by the Ministry of Education, Culture, Sports, Science and Technology of Japan.

N2 - We report on Cu/amUiO-66, a composite made of Cu nanoparticles (NPs) and amorphous [Zr6O4(OH)4(BDC)6] (amUiO-66, BDC=1,4-benzenedicarboxylate), and Cu-ZnO/amUiO-66 made of Cu-ZnO nanocomposites and amUiO-66. Both structures were obtained via a spray-drying method and characterized using high-resolution transmission electron microscopy, energy dispersive spectra, powder X-ray diffraction and extended X-ray absorption fine structure. The catalytic activity of Cu/amUiO-66 for CO2 hydrogenation to methanol was 3-fold that of Cu/crystalline UiO-66. Moreover, Cu-ZnO/amUiO-66 enhanced the methanol production rate by 1.5-fold compared with Cu/amUiO-66 and 2.5-fold compared with γ-Al2O3-supported Cu-ZnO nanocomposites (Cu-ZnO/γ-Al2O3) as the representative hydrogenation catalyst. The high catalytic performance was investigated using in situ Fourier transform IR spectra. This is a first report of a catalyst comprising metal NPs and an amorphous metal–organic framework in a gas-phase reaction.
