Summary: Selective catalytic oxidation is crucial in fine chemical and petrochemical industries, but it is challenging to achieve selective production of target products in the presence of multiple reaction paths. Single atom catalysts, different from nanoclusters and nanoparticles, offer opportunities for highly selective catalytic oxidation. This review summarizes recent advances in using novel catalytic materials for challenging selective oxidation reactions, including methane oxidation, alcohol oxidation, alkene epoxidation, and carbon monoxide oxidation. The key factors affecting catalytic performance, such as the electronic and geometric structures of single atoms, nanoclusters, and nanoparticles, are discussed. Understanding the active species, structures, activity-structure relationship, and mechanisms of these catalytic systems are highlighted, along with current challenges and future developments, aiming to guide the design of efficient and highly selective catalysts for heterogeneous oxidation reactions and to better understand their catalytic behaviors in a unified way.

Summary: Ni60Co40 nanoparticles supported on gamma-Al2O3 are capable of catalysing the steam reforming of methane and providing the necessary heat by induction heating. The temperature reached on the catalyst surface is influenced by metal loading and particle size distribution, affecting the ability of ferromagnetic nanoparticles to convert the radio frequency field into heat effectively. The catalyst pellets demonstrated effectiveness in achieving high temperatures and methane conversion rates during the steam methane reforming reaction.

Summary: Infrared spectra of adsorbate vibrational modes are accurate and easily obtainable for characterizing single-crystals and large nanoparticles, but not for highly dispersed heterogeneous catalysts composed of single-atoms and ultra-small clusters. In this study, the authors developed a method to generate synthetic IR spectra using data-based approaches and physics-driven surrogate models. They bypassed the vast combinatorial space of clusters by determining viable structures using machine-learned Hamiltonians, genetic algorithm optimization, and grand canonical Monte Carlo calculations. The synthetic spectra were used to predict cluster size distributions and quantify uncertainty in CO adsorption on Pd/CeO2 catalysts.

Summary: In this study, nickel-doped carbon dots (Ni-CDs) with tunable fluorescence emission were successfully synthesized using a simple one-step solvothermal method. The introduction of Ni enhanced the fluorescence intensity and caused a redshift. By mixing Ni-CDs with polyvinylpyrrolidone (PVP), the self-quenching effect of solid-state fluorescence was effectively avoided. Based on this, high-performance green, yellow, and red light-emitting diodes (LEDs) were constructed, demonstrating the potential of these carbon dots for solid-state lighting applications.

Summary: Metal halide perovskite materials have attracted attention for lighting applications due to their unique optoelectronic properties. However, their complex preparation processes and toxicity of lead restrict their practical use. This study reports Sb3+ and Bi3+ doping of 0D (NH4)2SnCl6 perovskite powders, which exhibit wide emission peaks at different wavelengths with high photoluminescence quantum yield (PLQY). The mechanisms of the doping effects are proposed based on experimental and theoretical analysis. Both Sb3+ and Bi3+ dopings enhance the air and thermal stability of 0D (NH4)2SnCl6 perovskites, showing great potential for solid-state lighting.

Summary: In this paper, amorphous ZIF-8 was modified with carboxyl functional groups (H3BTC-ZIF-8) to load organic fluorescent dyes (R6G and C151) and prepare R6G/C151/H3BTC-ZIF-8 composite films. The enhanced fluorescence properties were attributed to the increased interactions between the dyes and H3BTC-ZIF-8, which reduced the ACQ effect and resulted in a white-light-emitting composite film with high photoluminescence quantum yield (PLQY). This strategy provides guidance for the development of white-light-emissive materials.

Summary: In this study, Sb3+-doped Cs2ZrCl6 crystals with excellent optical properties and stability were successfully synthesized. The crystals exhibited blue and orange-red emissions under 254 nm and 365 nm light, respectively, attributed to the presence of [ZrCl6]2- and [SbCl6]3- octahedra. The Cs2ZrCl6:xSb(3+) crystals with a PLQY of up to 52.5% showed potential for white light-emitting diode (WLED) fabrication.

Summary: W18O49 shows strong Localized Surface Plasmon Resonance (LSPR) effect and unique oxygen-deficient structure, making it widely used in photothermal application and photocatalyst. The photochromic feature of W18O49 has seldom been studied due to the challenge of exploring its features in the saturated colored state. However, the researchers found that the bleached W18O49 obtained by mild-heating the synthesized blue W18O49 nanoparticles in air had considerable reversible photochromic feature, which has great potential in energy-saving smart windows application.

Summary: Precise and efficient patterning of light-emitting structures in high resolution and full-color light-emitting diodes is achieved by light-induced inverted patterning of nanocrystals in glasses for micro-light-emitting diodes. This method involves the use of ultrafast laser pulse to induce structural destruction and amorphization of nanocrystals in glasses, resulting in inverted luminescent patterns. The high-throughput patterning of micrometer-scale, thermally stable, and highly photoluminescent structures in nanocrystals embedded glass provides a novel way to fabricate high-performance and ultrahigh-resolution color conversion layers for micrometer-scale light-emitting diodes.

Summary: In this study, the Fermi-level (E-F) shift of the UV-illuminated Ag/TiO2 system under gaseous conditions was evaluated using in situ photoconductance and theoretical analysis. The role of Ag nanoparticles in storing and separating electrons was discussed, and it was found that the E-F of Ag/TiO2 is located deeper in the gap and is less affected by temperature compared to undecorated TiO2. The analysis showed that approximately 46 electrons can be stored in 10 nm Ag nanoparticles under the experimental conditions, and the blue-shift of localized surface plasmon resonance (LSPR) in Ag nanoparticles is not related to electron storage.

Summary: A targeted high-precision luminescence thermometer was designed using a lead-free double perovskite platform by selecting multiple thermally coupled levels (TCLs) of the Er3+ ion. By choosing different TCLs in a single system platform, more precise temperature resolution can be obtained in different temperature regions from 100 K to almost 880 K. This work provides a quantitative guideline for the development of the next generation of temperature sensor based on trivalent erbium ions.

Summary: Luminescent solar concentrators (LSCs) are semi-transparent windows that generate electricity from sunlight absorption. Despite their potential for building-integrated photovoltaics (BIPV), the current power conversion efficiency (PCE) of LSCs is still very low, limiting their practical applications. This Perspective summarizes and reviews the latest developments in LSCs, focusing on the future possibilities of higher PCE, large-scale production, and durability. It promotes the use of uniform testing standards and addresses the need for industrial development, toxicity concerns, and durability issues. A critical assessment of the field is provided, followed by discussions on challenges and solutions.
