Abstract Constructing S-scheme heterojunctions proves proficient in achieving the spatial separation of potent photogenerated charge carriers for their participation photoreactions. Nonetheless, restricted contact areas between two phases within heterostructures lead to inefficient interfacial transport, resulting low photocatalytic efficiency from a kinetic perspective. Here, In 2 O 3 /Nb 5 are fabricated through straightforward one-step electrospinning technique, enabling intimate and thereby fostering ultrafast electron transfer (<10 ps), as analyzed via femtosecond transient absorption spectroscopy. As result, powerful photo-electrons holes accumulate Nb conduction band valence band, respectively, exhibiting extended long lifetimes facilitating involvement subsequent Combined with efficient chemisorption activation stable CO on , hybrid nanofibers demonstrate improved performance conversion.

通过传统熔盐法合成的聚三嗪亚胺(PTI)其六棱柱晶体倾向于沿熔盐模板生长为聚晶形态, 这使得其侧面活性面难以充分暴露. 在本文中, 我们通过耦合熔盐法和硬模板法制备得到了具有高结晶性和侧面暴露的PTI纳米球. 研究表明, 熔点合适的LiCl/NaCl二元熔盐促进了高结晶六棱柱的形成, 此外, 三维模板使六棱柱能够沿空间分离方向定向生长. 优化后的PTI显示出具有完全扩展的π共轭聚合结构, 且具有空间暴露更完全的活性晶面. 因此, 制备得到的PTI纳米球光催化全分解水性能得到显著提升.

Abstract The development of high‐density and closely spaced frustrated Lewis pairs (FLPs) is crucial for enhancing catalyst activity accelerating reaction rates. However, constructing efficient FLPs by breaking classical bonds poses a significant challenge. Here, this work has made pivotal discovery regarding the Jahn–Teller effect during formation grain boundaries in carbon‐encapsulated Ni/NiOx (Ni/NiO x @C). This facilitates O (V ) Ni vacancy sites with different charge polarities, specifically FLP‐V ‐C basic acidic sites. synergistic interaction between not only reduces energy barriers water adsorption splitting, but also induces strong photothermal effect. mutually reinforcing contributes to exceptional performance Ni/NiO @C as cocatalyst photothermal‐assisted photocatalytic hydrogen production. Notably, @C/g‐C 3 N 4 (NOCC) composite photocatalyst exhibits remarkable production rate 10.7 mmol g −1 h , surpassing that Pt 1.76 times. Moreover, NOCC achieves an impressive apparent quantum yield 40.78% at wavelength 380 nm. paves way designing novel defect‐state multiphase cocatalysts adjacent FLP sites, which hold promise various catalytic reactions.
