S-Scheme Bi-oxide/Ti-oxide Molecular Hybrid for Photocatalytic Cycloaddition of Carbon Dioxide to Epoxides

Caiyun Liu et al.

Summary: Lewis acidic sites and reducing power are crucial for the performance of a photocatalyst in CO2 activation for cycloadditions. In this study, a Ti(18)Bi(4)O(29)Bz(26) cluster molecule was designed and synthesized with Lewis acidic sites on the surface, incorporating Ti18O22 and Bi4O7 cluster counterparts to form an S-scheme heterojunction. The photocatalyst showed enhanced reducing power and spatial separation of photogenerated charges, resulting in increased conversion rate and selectivity of the cyclocarbonate product in the presence of light.

Layered KTO/BiOCl nanostructures for the efficient visible light photocatalytic degradation of harmful dyes

Mani Durai et al.

Summary: Novel KTO/BiOCl nanostructured photocatalysts with various weight proportions were synthesized using a hydrothermal process. The as-prepared catalysts were characterized and exhibited improved photoresponsivity due to the heterojunction between KTO and BiOCl and the narrowed bandgap. The KTO/BiOCl nanostructure showed superior photocatalytic performance compared to bare BiOCl and titanate.

Visible light driven antibiotics degradation using S-scheme Bi2WO6/CoIn2S4 heterojunction: Mechanism, degradation pathways and toxicity assessment

Zuji Li et al.

Summary: In this study, S-scheme Bi2WO6/CoIn2S4 heterojunctions were synthesized and the photo-induced carriers transfer mechanism was clarified using various analysis methods. The results showed that Bi2WO6/CoIn2S4 with CoIn2S4 nanoclusters growing on the surface of Bi2WO6 nanosheets exhibited enhanced light absorption and more efficient carriers separation. A TC degradation efficiency of 90% was achieved by Bi2WO6/CoIn2S4 (15:1) within 3 hours of irradiation, with O-2(-) and OH radicals playing a dominant role. Additionally, possible decomposition pathways of TC were proposed, and most of the intermediates exhibited lower ecotoxicity than TC.
