“…16 A step-scheme photocatalyst made of sulfurized graphitic carbon nitride/ cobalt-doped zinc ferrite (S-g-C 3 N 4 /Co-ZF) was also reported by this group using a hydrothermal process. 17 Various cobalt-substitution ratios (SFCM, x = 0, 0.5, 0.75, and 1) were chosen as the pioneering method to assess SOFC efficacy in H 2 −H 2 S. Investigations into the results of cobalt replacement on the electrochemical, catalytic, and crystallite structures led to a better understanding of the structural flaws in SFCM brought on by cobalt doping. In a reducing environment, a series of cobalt-substituted SFCM (x = 0, 0.5, 0.75, and 1) were created, and their double-perovskite structures were established.…”
