dc.description.abstract | Photocatalytic degradation of harmful organic pollutants in water has been considered an important research subject due to its efficient and cost-effective handling of toxic substances for ecosystems protection. We report a direct Z-scheme heterojunction photocatalyst made up of NiMoO4/g-C3N4 (NMOCN) nanocomposite for degrading the antibiotic, i.e., ciprofloxacin (CIP) and the organic dye, i.e., malachite green (MG). The nano -composites were systematically prepared, and their structural, morphological, optical, and photoelectrochemical properties were analyzed. XRD analysis verified that NiMoO4 had a monoclinic crystal structure. The FESEM and HRTEM images showed that NMOCN composites were comprised of NiMoO4 nanorods coupled with g-C3N4 nanosheets. UV-VIS absorbance spectral analyses showed that NMOCN composites had a narrow band gap with good visible light absorption properties. Mott-Schottky and EIS measurements revealed that NMOCN composites had an optimum band structure and low charge transfer resistance for heterojunction formation. Increasing the relative mass content of g-C3N4 in NMOCN composites improved the photocatalytic degradation efficiency. NMOCN-30 (30 wt.% of g-C3N4) composite provided a maximum degradation efficiency, i.e., 90.82% for CIP (in 75 min) and 98.84% for MG (in 120 min), while showing excellent stability against CIP and MG up to six consecutive cycles. In addition, the EPR measurement and trap test results proved that all & sdot;OH, & sdot;O2-, and h+ participated in photodegradation activity. Thus, the presented nanocomposite photocatalysts with a Z-scheme heterojunction can help to build up a viable strategy for water pollution treatment with enhanced photocatalytic degradation capabilities. | - |
