A water-stable organolead iodide material for overall photocatalytic CO2 reduction

چکیده
The utilization of perovskites as photocatalysts to convert CO2 into fuels and chemicals has received wide attention recently. However, their instability in water hinders long-term application for overall photocatalytic reduction. Herein, we integrate the water-stable perovskite-like organolead iodide crystalline material [Pb8I8(H2O)3]8+[−O2C(CH2)4CO2−]4 (TJU-16) with Au co-catalyst reduction aqueous solution without sacrificial reagent. Under AM 1.5 G simulated illumination, TJU-16 0.19 wt.‰ steadily generated electrons reaction, which was 2.2 times pure TJU-16. Au0.19/TJU-16 catalyzed at a rate 84.2 µmol·g−1·h−1, achieved solar-to-fuel (STF) conversion efficiency 0.034%. Our work will motivate rational design materials applications.

A stable ZnCo2O4 cocatalyst for photocatalytic CO2 reduction.
Spinel ZnCo2O4 nanostructures have shown great opportunities in energy related areas. However, the applications of ZnCo2O4 for the conversion of CO2 are much less reported. Herein, we present the use of mesoporous ZnCo2O4 nanorods as efficient and high stable cocatalysts for the photochemical reduction of CO2 under mild reaction conditions.

متن کاملAn integrated photocatalytic/enzymatic system for the reduction of CO2 to methanol in bioglycerol–water
A hybrid enzymatic/photocatalytic approach for the conversion of CO2 into methanol is described. For the approach discussed here, the production of one mol of CH3OH from CO2 requires three enzymes and the consumption of three mol of NADH. Regeneration of the cofactor NADH from NAD(+) was achieved by using visible-light-active, heterogeneous, TiO2-based photocatalysts. The efficiency of the rege...
