为了设计和开发有效的可见光响应型人工光催化体系，间苯二酚-甲醛（RF）树脂聚合物光催化剂得到了广泛的研究。采用水热合成法系统地制备了不同组成的RF树脂聚合物微粒。采用UV-vis、XRD、SEM、FT-IR、电化学阻抗谱、光电化学响应和密度泛函理论计算等手段对RF聚合物进行了表征。重点研究了RF聚合物的R/F摩尔组成和制备温度对它们光催化氧化O2和H2O生成H2 O2活性的影响。此外，研究还发现苯环型OH与醌C双键O相互作用形成的电荷转移络合物在可见光催化反应中起着重要作用.
For design and development of effective visible-light responsible artificial photocatalytic system, resorcinol-formaldehyde (RF) resin polymer photocatalysts have been extensively studied. The RF resin polymer fine particles with different compositions were systematically prepared by hydrothermal synthesis. The RF polymers were characterized by UV–vis, XRD, SEM, FT-IR, electrochemical impedance spectroscopy, photoelectrochemical response, and DFT calculation. Attention was much paid to effects of R/F molar compositions and the preparation temperatures of the RF polymers on their photocatalytic activities for H2O2production from O2and H2O. Furthermore, the charge transfer complexes formed by the interaction of benzenoid OH with quinone Cdouble bondO were found to play a vital role in the photocatalytic reactions under visible-light irradiation.
