interfacial contact has been successfully fabricated, which exhibits significantly elevated photocatalytic performance toward coevolution of benzaldehyde (2.17 mmol/h/g) and hydrogen (1.97 mmol/h/g) from biomass-derived benzyl alcohol in aqueous solution under the visible light irradiation. Mechanistic studies reveal that in this ternary heterostructure, graphene serves as an electron relay mediator to facilitate
抽象的 通过同时利用光生空穴和电子,在温和条件下高度选择性地将生物质衍生化学物质光催化转化为增值化学物质和清洁氢能,这符合绿色化学可持续发展的主题。在此,三元Ni 2 P-石墨烯-纤铁矿TiO 2(NPG-TiO 2)与界面紧密接触已成功制备,在可见光下,其对水溶液中的生物质衍生的苯甲醇中的苯甲醛(2.17 mmol / h / g)和氢气(1.97 mmol / h / g)的共演化具有显着提高的光催化性能。光照射。机理研究表明,在这种三元异质结构中,石墨烯作为电子中继介体,由于其固有的电导率和Ni 2,促进了电子从TiO 2到Ni 2 P的流动。P提供了将光催化质子还原为氢的活性位点。预计这项工作将有助于合理设计二维平面结构多组分光催化剂,以选择性转化生物质衍生的化学物质并释放出氢气。 图形摘要
