Abstract

We reported the wavelength-dependent quantum efficiency phenomenon for the PCET reactions between alcohol and tBu3ArO˙ photocatalyzed by CdS or In2O3 for the first time. The excess energy beyond the lowest excited state energy level from incident photons can be introduced into the heterogeneous reaction, resulting in a significant impact on the kinetic rate.

半导体光催化反应的Anti-Kasha规则:量子效率的波长依赖性
本文首次报道了CdS或In2O3光催化的醇与tBu3ArO•之间的PCET反应的波长相关量子效率现象。来自入射光子的超过最低激发态能级的多余能量可以引入到非均相反应中,从而对动力学速率产生显著影响。

期刊介绍: Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
