Photocatalytic turnover number & turnover frequency of 4-HNB under solar light by ‘1’ photocatalyst with & without reducer

 4-hydroxynitrobenzene (4-HNB) is a highly effective industrial pollutant that causes adverse effects to human beings. In this regard, detoxification of noxious water is utmost indispensable. Highly efficient metal-free photocatalytic degradation and reduction of 4-HNB with and without reducing agent still challenge. Additionally, for this role, largely expensive reagents that can create inauspicious impacts on the environment are utilized. Herein, we developed a ‘1’ photocatalyst that has the excellent ability for the H2O2-mediated degradation and reductant-free reduction of 4-HNB. The ‘1’ photocatalyst has an excellent turnover number (TON) 0.644×1020 molecules and turnover frequency (TOF) 0.0035×1020 molecules /min.
