a CO yields of four parallel experiments of pure-water PCRs. The first used BOC-VDWGs-AL under visible light in the presence of CO2, the second did not involve BOC-VDWGs-AL but still using visible light and CO2, the third involved BOC-VDWGs-AL and CO2 but under dark, and the fourth employed BOC-VDWGs-AL and visible light but fed with argon. b Cycling tests of pure-water PCR performances over BOC-VDWGs-AL for 50 hours. c Mass spectra of the product generated from pure-water PCR over visible-light-irradiated BOC-VDWGs-AL fed with 13CO2. The inset in panel c shows the corresponding GC pattern. d Yield of O2 detected during pure-water PCR photocatalyzed by BOC-VDWGs-AL, as well as the calculated yield ratio of CO to O2. This set of data were obtained from an online PCR system. e Statistical result for the CO/O2 yield ratio. f Comparison of CO-evolving rate of BOC-VDWGs-AL, CBOC-VDWGs, and BOC-VDWGs-76, all under visible light in the presence of pure-water and CO2. g Comparison of pure-water, CO-evolving rate of BOC-VDWGs-AL and some representative layered photocatalysts. The nanosheet photocatalysts with VDWGs on lateral facets were obtained by conventional exfoliation method, while VDWGs-dominated nanosheets were synthesized by our developed exfoliation strategy. The error bars derived from triplicate experiments.
