Summary: Considering the high toxicity of hexavalent chromium ions (Cr6+) and its threat to human health and the environment, it is of great significance to develop a rapid and accurate sensing platform for detecting this toxic substance. In this study, nitrogen and boron co-doped carbon quantum dots (N, B-CQDs) derived from lignin were synthesized and used as fluorescent sensors for the detection of Cr6+. The N, B-CQDs showed triple emission and were applied for triple-channel detection, exhibiting highly sensitive and selective fluorescence quenching for Cr6+. The utilization of renewable lignin as a basis for CQDs-based fluorescent sensors opens up a new approach for the rapid and accurate detection of Cr6+ through a multi-channel sensing platform.

Summary: This study measured the actual reaction temperature of photothermal ammonia synthesis over carbon-supported Ru catalyst using Le Chatelier's principle, and found that the activation energy for photothermal catalysis was much lower than thermocatalysis. This was attributed to hot-electron injection reducing the energy barriers for N2 dissociation and intermediates hydrogenation, while also suppressing carbon support methanation. The catalyst exhibited outstanding operational stability over 1000 hours. This work provides new insights into the effects of hot electrons in ammonia synthesis and guides the design of high-performance photothermal catalysts.

Summary: Water and soil pollution caused by toxic cadmium ions (Cd2+) pose a serious threat to living organisms. Finding low-cost mineralizers that can effectively immobilize Cd2+ ions is crucial for wastewater treatment and soil remediation. In this study, a novel mineralizer, magnesium-aluminum layered double hydroxide (MgAl-LDH), was developed and demonstrated high capacity and selectivity for Cd2+ removal. The mineralizer reduced the Cd2+ concentration in aqueous solution from 100 ppm to less than 50 ppb within 15 minutes, meeting the discharge standard of industrial wastewater. This work highlights the potential of defect-engineered LDH materials for the selective removal of heavy metals from polluted water.

Summary: In this study, ultrasmall Ru nanoparticles anchored on MnCo2O4 nanosheets were found to be effective photothermal catalysts for CO2 methanation under light irradiation. The optimized Ru/MnCo2O4-2 exhibited high CH4 production rate and selectivity, outperforming most reported plasmonic metal-based catalysts. The improved catalytic performance was attributed to enhanced charge separation efficiency, improved reaction kinetics, facilitated reactant adsorption/activation, and accelerated intermediate conversion under light irradiation over Ru/MnCo2O4.

Summary: We investigate the interface properties between WSi2N4 and Mo2B, O-modified Mo2B, and OH-modified Mo2B nanosheets. We find that WSi2N4 and Mo2B form n-type Schottky contacts, while functionalizing Mo2B with O and OH leads to the formation of both n-type and p-type ohmic contacts with WSi2N4. Additionally, we demonstrate the emergence of quasi-ohmic contact with ultralow lateral Schottky barrier and zero vertical interfacial tunneling barriers in Mo2B(OH)2-contacted WSi2N4.

Summary: When rare-earth ions are embedded in a ferroelectric material, their photoluminescence can serve as an all-optical probe for temperature, electric field, and mechanical stimulus. However, the impact of ferroelectric phase transitions on photoluminescence is not well understood. In this study, we demonstrate changes in the photoluminescence of green emission bands during critical ferroelectric transitions in an Er-doped BaTiO3 material. We also find that the intensity ratio and wavelength position difference of sub-peaks provide information on the phase transitions.
