Synergistic utilization of TiO<sub>2</sub>-photo-generated holes and electrons is a potential protocol for catalytic C–C bond formation reactions.
Constructing a favorable reaction configuration at the water/catalyst interface is crucial for high-efficiency semiconductor-based water splitting. For long time, hydrophilic surface of semiconductor catalysts has been considered necessary efficient mass transfer and adequate contact with water. In this work, by constructing superhydrophobic PDMS-Ti3+/TiO2 (denoted P-TTO) nanochannels arranged nonpolar silane chains, we observe overall splitting efficiencies improved an order magnitude under...
The fast OH- transfer between hydroxide layers is the key to enhancing charge storage efficiency of layered double hydroxides (LDH)-based supercapacitors (SCs). Constructing interlayer reactive sites in LDH much expected but still a huge challenge. In this work, CdS nano-dots (NDs) are introduced interlayers ultra-thin NiFe-LDH (denoted CdSinter. -NiFe-LDH), promoting ions flow for higher redox activity. excellent performance not only due enlarged layer spacing (from 0.70 0.81 nm) also stems...
Conventional photocatalysts generate numerous active species—primarily hydroxyl radicals (•OH)—under solar light excitation to exert photocatalytic activity for especially antibacterial effects. However, the dependence limits their competitiveness against other antimicrobial materials since they do not work at night. Herein, a P-g-C3N4/Sr2MgSi2O7:Eu2+,Dy3+ (P-g-C3N4/SMSO) composite day–night photocatalyst is synthesized, using model methyl orange (MO) substrate, and impacts of trace P doping...
For degradation of β-lactam antibiotics pollution in waters, the strained ring is most toxic and resistant moiety to biodegrade redox-chemically treat among their functional groups. Hydrolytically opening with Lewis acid catalysts has long been recognized as a shortcut, but at room temperature, such hydrolysis too slow be deployed. Here, we found when Cu 2+ was immobilized on imine-linked COF (covalent organic framework) (Cu /Py-Bpy-COF, load 1.43 wt%), as-prepared composite can utilize...
Abstract Direct solar-to-hydrogen conversion from pure water using all-organic heterogeneous catalysts remains elusive. The challenges are twofold: (i) full-band low-frequent photons in the solar spectrum cannot be harnessed into a unified S 1 excited state for water-splitting based on common Kasha-allowed 0 → excitation; (ii) H + 2 evolution suffers high overpotential pristine organic surfaces. Here, we report an molecular crystal nanobelt through self-assembly of spin-one open-shell...

Covalent organic frameworks (COFs) are defined as highly porous and crystalline polymers, constructed connected via covalent bonds, extending in two- or three-dimension. Compared with other materials such zeolite active carbon, the versatile alternative constituent elements, chemical bonding types characteristics of ordered skeleton pore, enable rising large family COFs more available to diverse applications including gas separation storage, optoelectronics, proton conduction, energy storage...
The T1–T2 dual-mode contrast agents for magnetic resonance imaging (MRI) can generate self-complementary confirmed T2 and T1 images, hence greatly improving the reliability. Facilely synthesizing nanoparticles with ultrasensitive property remains extremely challenging in nanoscience. Moreover, uncovering mechanism correlating signal enhancements chemical constituents is vital designing novel efficient synergistically enhanced MRI nanoprobes. Herein, we report a one-pot facile method to...
Abstract Photocatalytic redox reactions are important for synthesizing fine chemicals from olefins, but the limited lifetime of radical cation intermediates severely restricts semiconductor photocatalysis efficiency. Here, we report that Ag 3 PO 4 can efficiently catalyze intramolecular and intermolecular [2 + 2] Diels-Alder cycloadditions under visible-light irradiation. The approach is additive-free, catalyst-recyclable. Mechanistic studies indicate irradiation on generates holes with high...
Fulfilling the direct inert C–H bond functionalization of raw materials that are earth-abundant and commercially available for synthesis diverse targeted organic compounds is very desirable its implementation would mean a great reduction synthetic steps required substrate prefunctionalization such as halogenation, borylation, metalation. Successful mainly resorts to homogeneous transition-metal catalysis, albeit sometimes suffering from poor catalyst reusability, nontrivial separation,...
As one of the most promising semiconductor oxide materials, titanium dioxide (TiO2) absorbs UV light but not visible light. To address this limitation, introduction Ti3+ defects represents a common strategy to render TiO2 visible-light responsive. Unfortunately, current hurdles in generation technologies impeded widespread application modified materials. Herein, we demonstrate simple and mechanistically distinct approach generating abundant surface-Ti3+ sites without leaving behind oxygen...
The surface property of a photocatalyst, including acid sites and oxygen vacancies, plays pivotal role in photocatalytic organic synthesis reactions. Benzoin isopropyl ether (BIE) is usually produced via polycondensation benzaldehyde catalyzed with highly toxic cyanide. Here, we report green approach for the selective BIE over WO3 driven by green-light-emitting diode. improved activity can be attributed to synergy vacancies (VOs) N-doped nanobelts. results revealed that reactant molecules...
