Реферат:
The interface modulation significantly affects the photocatalytic performances of supported metal phthalocyanines (MPc)-based systems. Herein, ZnPc was loaded on nanosized Au-modified TiO2 nanosheets (Au-T) to obtain wide-spectrum ZnPc/Au-T photocatalysts. Compared with large Au NP (8 nm)-mediated ZnPc/Au-T photocatalyst, ultrasmall Au NP (3 nm)-mediated one shows advantageous photoactivity, achieving 3- and 10-fold CO2 conversion rates compared with reference ZnPc/T and pristine TiO2 nanosheets, respectively. Employing monochromatic beam-assisted surface photovoltage and photocurrent action, etc., the introduction of ultrasmall Au NPs more effectively facilitates intrinsic interfacial charge transfer. Moreover, ZnPc molecules are found more dispersed with the existence of small Au NPs hence exposing abundant Zn2+ sites as the catalytic center for CO2 reduction. This work provides a feasible design strategy and renewed recognition for supported MPc-based photocatalyst systems.
