	abstract = {Fe2O3, as an earth-abundant photocatalyst for water purification, has attracted great attention. However, the high-spin FeIII in traditional Fe2O3 restricts its catalytic performance. In this work, based on the nanocrystal size alteration strategy, cubic Fe2O3 nanoclusters (3{\textendash}4~nm) with low-spin FeIII were successfully anchored on six-fold cavities of the supramolecular condensed g-C3N4 rod (FCN) through the impregnation-coprecipitation method. FCN showed high photocatalytic activity, as the d band center of Fe 3d orbital (-1.79~eV) in low-spin FeIII shifted closer to Femi level, generating a weaker antibonding state. Then, the enhanced bonding state strengthened the interaction between Fe and O, further accelerating the charge carrier separation and enhancing its ability to capture OH-. Thus, low-spin FeIII enhanced the production of dominant reactive oxygen species ({\textbullet}OH/{\textbullet}O2-), promoting diclofenac photocatalytic degradation under solar light, with a kinetic rate constant (0.206~min-1) of ~5 times compared with that of pristine g-C3N4.},
