Preparation method and application of DBF resin organic photocatalyst

The invention discloses a preparation method and application of a DBF resin organic photocatalyst, the preparation method is a hydrothermal method, and the DBF resin organic photocatalyst with wide spectrum absorption, high activity and proper energy band is prepared. Due to the existence of phenolic hydroxyl groups, oxygen can be effectively adsorbed, formation of H2O2 is facilitated, the prepared DBF resin organic photocatalyst has an electron donor-acceptor (D-A) structure pair, and a favorable medium transmission channel is provided for separation of photo-generated holes and electrons; through pi-pi stacking and interaction between D-A structure pairs, a larger delocalized pi-electron conjugation system and an energy level matched structure are constructed, and the separation and migration efficiency of photo-induced electron-hole pairs is improved. 本发明公开了一种DBF树脂有机光催化剂的制备方法及应用，其中制备方法为水热法，制备得到宽光谱吸收、高活性和能带适合的DBF树脂有机光催化剂；由于存在酚羟基，能有效的吸附氧气，有利于H2O2的形成，制备的DBF树脂有机光催化剂具有电子供体-受体(D-A)结构对，为光生空穴和电子的分离提供了有利介质传输通道；D-A结
