A 0D/2D Heterojunction Composite of Polymeric Carbon Nitride and ZIF-8-Derived ZnO for Photocatalytic Organic Pollutant Degradation

Solar photocatalytic technology based on semiconducting materials has gained the attention of scientific community to solve energy crisis and environmental remediation. Zeolitic imidazolate frameworks (ZIFs) are a subfamily metal–organic (MOFs) with isomorphic topologies zeolites coordinative compositions MOFs. Owing high specific surface areas, tunable channels thermal stabilities, zeolitic have been used in catalytic applications. In this paper, ZIF-8 was as matrix synthesize 0D/2D heterojunction photocatalysts, viz., ZnO/C3N4-x% (x = 2.5, 5 10), for degradation study rhodamine B (RhB). The synthesized composite were characterized using FTIR, PXRD, UVDRS, PL, TEM, BET analyses. TEM images showed nearby contacts between ZnO C3N4 hybrid uniform distribution nanosheet, thus increasing development heterojunction. system ZnO/C3N4-5% (ZCN-5) good activity RhB under sunlight. A possible mechanism improved ZnO/C3N4 is also suggested. This exploratory demonstrates effective separation migration photo-induced electron–hole pairs 2D sheet 0D performance photocatalysts.
