In the face of increasing global carbon dioxide emissions and the urgent need to mitigate
climate change, the development of efficient and sustainable strategies for CO2 conversion has
gained significant attention. One of the methods of eliminating the harmful effects of CO2
is its
photoreduction. In this paper, ZnO was used as an effective photocatalyst for the photoreduction of
CO2
in a gas-phase system. The influence of particle size on the process efficiency was investigated.
The ZnO materials applied in the studies were characterized using XRD, SEM, and low-temperature
nitrogen adsorption (BET) methods. The pore volume distribution was calculated based on the DFT
method. The investigation confirmed that it had a significant impact on the formation of the product
of photocatalysis carbon dioxide. The main identified product was carbon monoxide. Hydrogen and
methane were detected as well. Based on the results, it was found that the process efficiency was
enhanced with decreasing ZnO particle size, and the most effective catalyst for the photoreduction of
CO2 was the ZnO sample with the smallest particle size (18 nm).
