Abstract A morphology-controllable 0D/1D graphitic carbon nitride (g-C3N4, CN) homojunction (MUCN) was constructed by a facile in-situ thermal polymerization process using the melamine-cyanuric acid supramolecular (MCS) and urea as co-precursor. The as-prepare MUCN is stable with controllable and uniform morphology and exhibits significantly enhanced photocatalytic activities for RhB degradation and H2O2 production. The RhB degradation rate and the H2O2 production are ~37 times and 17 times higher than that of pure CN, respectively. The significantly enhanced photocatalytic performance is attributed to the synergetic effect of energy band controlling and structural coupling in MUCN, which can form the internal driving force to improve the separation efficiency of charge carriers. The results have provided a new effective way for promoting the practical photocatalytic application of CN.
