“…It was also hampered by the fast annihilation efficiency of the photoexcited charge carriers. The enhanced photodegradation performance of 99% within 180 min with CdS/TiO 2 /g-C 3 N 4 composite could be assigned to TiO 2 acting as a conductive bridge between CdS and g-C 3 N 4 and suppressing recombination of photoexcited charge carrier . RhB has an initial concentration ( C 0 ) at time 0 and final concentration ( C ) at time t of irradiation.…”

This study investigated a ternary CdS/TiO 2 /g-C 3 N 4 heterojunction for degrading synthetic dyes and hydrogen production from aqueous media through visible light-initiated photocatalytic reactions. CdS, TiO 2 , and g-C 3 N 4 were combined in different mass ratios through a simple hydrothermal method to create CdS/TiO 2 / g-C 3 N 4 composite photocatalysts. The prepared heterojunction catalysts were investigated by using FTIR, XRD, EDX, SEM, and UV−visible spectroscopy analysis for their crystal structures, functional groups, elemental composition, microtopography, and optical properties. The rhodamine B dye was then degraded by using fully characterized photocatalysts. The maximum dye degradation efficiency of 99.4% was noted in these experiments. The evolution rate of hydrogen from the aqueous solution with the CdS/TiO 2 /g-C 3 N 4 photocatalyst remained 2910 μmol• h −1 •g −1 , which is considerably higher than those of g-C 3 N 4 , CdS, CdS/g-C 3 N 4 , and g-C 3 N 4 /TiO 2 -catalyzed reactions. This study also proposes a photocatalytic activity mechanism for the tested ternary CdS/TiO 2 /g-C 3 N 4 heterojunctions.

In this study, NiFe2O4, ZnFe2O4, and MgFe2O4 catalysts are utilized to decompose plastic into hydrogen gas, liquids, and carbon nanotubes. Ferrite nanoparticles worked as a catalyst and heat susceptors for microwaves. MgFe2O4 catalyst resulted in highly structured carbon residue with fewer impurities than other catalysts. The oil yield of 13.5, 14, and 9.5 wt. % was obtained with NiFe2O4, ZnFe2O4, and MgFe2O4, respectively. Similarly, gas evolution was about 14, 13, and 12.5 wt. %, respectively. MgFe2O4 displayed superior H2 production efficiency of 90 % compared to the other two catalysts. These findings suggest high activity of MgFe2O4 catalyst compared to NiFe2O4 and ZnFe2O4 catalysts. This catalyst also showed stronger magnetic characteristics and reactivity.
