摘要
卟啉聚集体材料具有较强的可见光吸收能力、催化稳定性和光催化活性,被广泛应用于新型光催化剂和光敏剂的设计研究中。当卟啉的聚集模式和聚集形貌不同时,往往会表现出不同的光物理和光化学性质。为了研究卟啉的聚集形貌对卟啉的光催化活性的影响,采用溶剂挥发法和CTAB模板法合成了形貌不同的TDCPP聚集体材料,其中棒状TDCPP的产氢速率为447μmol·g^(-1)·h^(-1),米粒状TDCPP的产氢速率为305μmol·g^(-1)·h^(-1)。棒状形貌的TDCPP因含有更多的J型聚集而表现出更优异的光催化活性。
Porphyrin aggregates was widely used in the design and study of new photocatalysts and photosensitizers because of their strong visible light absorption capacity,catalytic stability and photocatalytic activity.However,when the aggregation mode and morphology of porphyrin aggregates were different,they often showed different photophysical and photochemical properties.In order to study the effect of porphyrin aggregation morphology on porphyrin photocatalytic activity,TDCPP aggregates with different morphology were synthesized by solvent volatilization method and CTAB template method.The hydrogen production rate of rod TDCPP was 447μmol/g/h,and the rice granular TDCPP was 305μmol/g/h.The rod-shaped TDCPP showed better photocatalytic activity because it contained more J-type aggregation.
