Summary: As climate change worsens, the challenges regarding CO2 such as emissions reduction and conversion into valuable products will remain for years. While there is extensive academic research on capturing and converting CO2, further evaluations under realistic conditions are necessary. Scaling up laboratory results to pilot plants is crucial for eventual commercialization. This perspective focuses on dual function materials (DFMs) as an example of a scalable approach to CO2 capture and catalytic conversion.

Summary: Integrated CO2 capture with reverse water gas shift (RWGS) reaction using Ni-CaO-CeO2 DFMs prepared by sol-gel method shows excellent ICCU-RWGS performance. The synthetic mode, precursor, and granulation process affect the physicochemical properties and ICCU performance of the DFMs. NiCaCe-SG (A) prepared using acetate salts as precursors exhibits better ICCU-RWGS performance than the nitrate precursors-derived NiCaCe-SG (N) DFMs. Granulation adversely affects the CO2 capture capacity, CO yield, and working stability of the NiCaCe-SG (N) sample. NiCaCe-SG (A) represents an excellent DFMs candidate for ICCU-RWGS.

Summary: Efficient CO2 conversion was achieved for the first time by synergistic interaction between Cs2SnCl6 photocatalyst and H2O-assisted dielectric barrier discharge (DBD) plasma. The conversion ratio of plasma photocatalysis was 6.5% higher than that of plasma or photocatalysis alone, indicating the successful synergy between plasma catalysis and photocatalysis. The presence of H2O increased the CO2 conversion ratio by 50.6% due to enhanced charge transfer.

Summary: Poly (4-styrenesulfonic acid) (PSSA) was utilized as a recoverable acid catalyst for hydrolysis of polyethylene terephthalate (PET) to terephthalic acid (TPA) and ethylene glycol (EG). The PSSA system exhibited faster hydrolysis kinetics than H2SO4 with better surface wetting of PET and higher localized concentration of protons. Reutilization and titration results indicated that PSSA maintained activity after five reaction cycles.
