a In situ FTIR spectra for the photocatalytic CO2 reduction over 3DOM Co-SNS; (b) free energy diagrams and (c) the configurations of adsorbates for the CO2 reduction processes on Co3S4, Co(OH)2 and Co3O4; (d) XPS spectra of Co 2p of 3DOM Co-SNS exposing to CO2 and visible light condition; (e) Configurations of HCOO*on Co3S4 and Co3O4; COHP analysis of (f) Co3S4-HCOO* and (g) Co3O4-HCOO*. Co, O, S, C, H atoms are colored in blue, red, yellow, silver and white, respectively. Source data are provided as a Source Data file.
