Fig. 17. In situ DRIFTS of Cu/ZnO in (a) H2/MeOH/H2O, Ar, and N2O atmospheres, (b) H2/EtOH/H2O, Ar, and N2O atmospheres, (c) H2/PrOH/H2O, Ar, and N2O atmospheres. Reproduced from ref. [226] (Copyright 2023, Wiley-VCH GmbH). (d) Normalized XANES spectra and (e) Fourier transforms of EXAFS spectra of 1ZnO/Cu(OH)2 (“1” denotes the number of ZnO atomic layer deposition cycles) during CO2 hydrogenation under a pressure of 0.8 MPa at different temperatures. (f)First derivative of the Zn K edge spectra of the 1ZnO/Cu(OH)2 inverse catalyst during CO2 hydrogenation at different temperatures. Reproduced from ref. [227] (Copyright 2022, Wiley-VCH GmbH). (g) In situ DRIFTS spectra for photocatalytic conversion of CH4 over ZnO-AuPd2.7%. (h) In situ EPR signals of ZnO-AuPd2.7% collected under different environments. Reproduced from ref.
