Abstract:

A key solution for high-efficiency solar-to-fuel conversion is to fabricate semiconductor photocatalysts with ultra-broad spectral absorption and high charge-carriers utilization efficiency [1]. The localized surface plasmon resonances (LSPR) effect of W18O49 induces visible and near-infrared (NIR) light absorption efficiently, realizing full-spectrum solar-light driven photocatalysis [2]. Therefore, it is meaningful to study the LSPR origin and seek ways to make full use of photo-induced hot electron of W18O49. In our work, by density-functional theory calculation, the LSPR has been proposed

Abstract:

It is well known that finding of Honda-Fujishima effect1 opened up the way to semiconductor photocatalysis. The semiconductor photocatalysts, typically TiO2, are often modified with noble metal nanoparticles such as platinum as co-catalysts, for improvement of the photocatalytic activity. We modified TiO2 photocatalysts with plasmonic silver2 or gold3 nanoparticles and found that plasmon-induced charge separation (PICS) occurs at the metal-TiO2 interface.3,4 If a metal nanoparticle such as silver or gold is irradiated with light of the resonant wavelength, energetic electrons and holes are gen

Abstract:

This contribution describes the self-assembling and self-activating nature of a TiO2 photocatalyst that generates hydrogen from water in the absence of sacrificial species or noble metal co-catalysts [1]. Such system forms when nanoparticles of reduced anatase TiO2 are illuminated in an aqueous Ni2+ solution [2,3]. UV illumination creates in-situ a Ni+/TiO2/Ti3+ photocatalyst that over time produces H2 at a higher rate. Thus, UV light is both the synthesis tool that forms this active metastable photocatalytic entity and the energy provider for this entity to enable H2 evolution from water. Ope

Ammonia is not only an indispensable feedstock to produce essential industrial chemicals like fertilizers, but it is also a potential hydrogen energy carrier owing to its high energy density and hydrogen capacity. Currently, most ammonia required for humans comes from the Haber–Bosch process, which contributes more than 90% of the annual global ammonia output. However, the harsh reaction conditions of this process result in serious energy and environmental issues.

Abstract:

Sensitized organic photon upconversion via triplet‐triplet annihilation (TTA) shows significant potential for energy conversion and photocatalysis, but achieving efficient upconversion across multiple wavelengths with single‐wavelength near‐infrared (NIR) excitation remains a daunting challenge. Here, we report a strategy utilizing lanthanide‐doped nanocrystals (LnNCs) to sensitize TTA upconversion in multiple organic emitters under NIR excitation, achieving an anti‐Stokes shift of up to 1.1 eV. This approach leverages a cascade lanthanide‐triplet energy transfer design, adopting an interfacia

Abstract:

AbstractPhoton upconversion of near-infrared (NIR) irradiation into ultraviolet-C (UVC) emission offers many exciting opportunities for drug release in deep tissues, photodynamic therapy, solid-state lasing, energy storage, and photocatalysis. However, NIR-to-UVC upconversion remains a daunting challenge due to low quantum efficiency. Here, we report an unusual six-photon upconversion process in Gd3+/Tm3+-codoped nanoparticles following a heterogeneous core-multishell architecture. This design efficiently suppresses energy consumption induced by interior energy traps, maximizes cascade sensiti

Abstract:

AbstractNear‐infrared (NIR) laser annealing is successfully used to crystallize TiO2 thin films from a sol–gel solution deposited on gold nanoparticle arrays (AuNPs). The AuNPs are used as nano‐heaters allowing a local temperature increase up to 500 °C in the film. The temperature reached under the laser is deduced from the presence of the anatase phase in the samples obtained by laser exposure, showing that crystallized TiO2 can be obtained by the photothermal effect. Different analytical techniques supported this study, such as grazing X‐ray diffraction (GIXRD), UV–vis, and Raman spectroscop

Abstract:

Abstract The inadequate quantity of hydrogen peroxide (H2O2) in cancer cells promptly results in the constrained success of chemodynamic therapy (CDT). Significant efforts made throughout the years, nevertheless, researchers are still facing the great challenge of designing a CDT agent and securing H2O2 supply within the tumor cell. In this study, taking advantage of H2O2 level maintenance mechanism in cancer cells, a nanozyme-based bimetallic metal-organic frameworks (MOFs) tandem reactor is fabricated to elevate intracellular H2O2 levels, thereby enhancing CDT.

AbstractPathological microenvironment of diabetes including hyperglycemia, excessive reactive oxygen species (ROS), and accumulation of advanced glycation end products leads to high risk of infection and persistent inflammatory reaction, retarding biointegration of implants. To address this issue, a dual‐catalysis system consisting of Na2TiO3 nanotubes with CeO2 nanodots and polydopamine (PDA) cover is constructed on Ti implant to manipulate ROS generation and scavenging for antibiosis and tissue regeneration. Na2TiO3 and CeO2 form heterojunction, in which oxygen vacancies (VOs) contribute to
