Photocatalytic Performance for CO2-to-CH4 Conversion with the Biohybrids
The CH4 yields by biohybrids with various Ni doping amounts (A); photocatalytic CH4 production by the M. barkeri-Ni(0.75%):CdS biohybrids and deletional controls (B); biomass variation of natural M. barkeri and M. barkeri-Ni(0.75%):CdS biohybrids (C); mass spectrometry of headspace gases with 12C-labeled NaHCO3 and 13C-labeled NaHCO3 as carbon sources in the media, respectively (D); photocatalytic CH4 yields and quantum efficiencies (% incident light) of the M. barkeri-Ni(0.75%):CdS biohybrids with a light-dark cycle of 1 day (E); photocatalytic CH4 production rates and quantum yields based on the initial Cys concentration under different light intensities (F). Data are represented as mean ± SEM (n = 3), and the different letters represented statistically significant difference (p < 0.05) in different groups.
