Rational design of a g-C3N4/CdS/MIL-125 (Ti)-derived TiO2 ternary heterojunction as a highly efficient photocatalyst for wastewater treatment under visible-light irradiation

A highly efficient g-C 3 N 4 /CdS/TiO 2 ternary heterojunction photocatalyst with a hollow structure has been fabricated using a step-by-step self-assembly strategy.
