Abstract：
Mixed-dimensional van der Waals heterojunctions (MD-vdWhs), known for exceptional electron transfer and charge separation capabilities, remain underexplored in photocatalysis. In this study, we leveraged the synergistic effect of intermolecular π → π* and D-π-A dual channels to fabricate novel MD-vdWhs. Owing to the synergistic effect, it exhibits superior electron transfer and delocalization ability, thereby enhancing its photocatalytic performance. The Optimal photocatalyst can degrade 98.78 % of 20 mg/L tetracycline (TC) within 15 min. Additionally, we introduced a novel proof strategy for investigating the photoelectron transfer path, creatively demonstrating the synergistic dual channels effect, which can be attributed to the carbonyl density and light-excitation degree. Notably, even under low-power light sources, it achieved complete inactivation of Escherichia coli within just 7 mins, far surpassing current cutting-edge research. This theoretical framework holds promise for broader applications within related studies.
摘要：
混合维范德华异质结(MD-vdWhs)，以卓越的电子转移和电荷分离能力而闻名，在光催化方面仍未充分开发。在这项研究中,我们利用分子间π→π*和D-π-A双通道的协同作用制造了新型MD-vdWhs。由于协同效应，它表现出优越的电子转移和离域能力，从而提高其光催化性能。最佳光催化剂可在15min内降解20mg/L四环素（TC）98.78％。此外,我们介绍了一种研究光电子转移路径的新证明策略，创造性地展示了协同双通道效应，这可以归因于羰基密度和光激发程度。值得注意的是,即使在低功率光源下，它在短短7分钟内实现了大肠杆菌的完全灭活，远远超过当前的前沿研究。这一理论框架有望在相关研究中得到更广泛的应用。
