Boosting CO<sub>2</sub> Conversion by Synergy of Lead-Free Perovskite Cs<sub>2</sub>SnCl<sub>6</sub> and Plasma with H<sub>2</sub>O
Although dielectric barrier discharge (DBD) plasma is
a promising
technique for CO2 conversion, realizing CO2-to-alcohol
is still challenging via the use of H2O. Herein, for the
first time, efficient CO2 conversion was achieved via the
synergism between the Cs2SnCl6 photocatalyst
and DBD plasma assisted by H2O. The CO2 conversion
ratio of plasma photocatalysis was 6.5% higher than that of only the
plasma and photocatalysis, implying that the synergism of plasma catalysis
and photocatalysis was achieved. Furthermore, the DBD plasma assisted
by the Cs2SnCl6 photocatalyst could convert
CO2 and H2O to CO and a small amount of methanol
and ethanol. The CO2 conversion ratio was enhanced by 50.6%
in the presence of H2O, which was attributed to the improvement
of charge transfer due to the increased electrical conductivity of
the photocatalyst surface during plasma discharge. This work provides
a new idea for developing an efficient system for CO2 utilization
