Pyridine CTF (CTF-Py) grafted on the surface of NH2-functionalized TiO2 (NH2-TiO2) nanoparticles gave composite TiO2@CTF-Py covalently linking the inorganic semiconductor to the nitrogen-rich porous, conjugated and coordinating organic functionality. Co2+-modified TiO2@CTF-Py was an efficient photocatalyst for the reduction of CO2 to CO with high selectivity using water as the electron donor and without exogenous photosensitizers or a sacrificial agent. The covalent connection between the semiconductors and NNN coordination group were important for this photocatalytic activity and selectivity.

Co 2+固定的共价三嗪骨架与TiO 2的共价键结合,以增强CO 2与H 2 O的光还原为CO
接枝到NH 2功能化的TiO 2(NH 2 -TiO 2)纳米颗粒表面上的吡啶CTF(CTF-Py)得到复合TiO 2 @ CTF-Py,将无机半导体共价连接到富氮的多孔,共轭和配位的有机物上功能。Co 2+改性的TiO 2 @ CTF-Py是一种高效的光催化剂,可以使用水作为电子给体,而无需使用外源光敏剂或牺牲剂,以高选择性将CO 2还原为CO 。半导体与NNN配位基团之间的共价连接对于这种光催化活性和选择性很重要。
