Fig. 3. — (A) C₂ hydrocarbon (C₂H_x) production for bare TiO₂, Pd₁-TiO₂-0.5, Pd₁-TiO₂, Pd₁-TiO₂-2, and Pd_n-TiO₂ following 3 hours of photoreaction. (B) Time-dependent photocatalytic C₂ hydrocarbon production for Pd₁-TiO₂. (C) Cyclic tests for Pd₁-TiO₂ with 3 hours per cycle. C₂ hydrocarbon production reported in (A) to (C) is expressed per mass of the photocatalyst. C₂H₄ selectivity is reported on the basis of the total C₂H_x yield. (D) Organic acid yields for TiO₂, Pd₁-TiO₂, and Pd_n-TiO₂ following 3 hours of photoreaction. (E) Activity summary for Pd₁-TiO₂ and reported photocatalysts for conversion of PE to the valued products. The photocatalysts for reported data are as follows: P25|Pt (7), MoS₂/CdS (45), and Nb₂O₅ (46).
