Summary: This study presents a strategy to enhance photothermal transformation and solar-to-fuel conversion by combining concentrated solar power and plasmonic nanomaterials. The researchers fabricated a nanocatalyst consisting of gold anchored on TiO2 using a regular deposition-precipitation method. The nanocatalyst exhibited improved performance in CO2 reduction under concentrated full-spectrum irradiation due to the coupling of photo- and thermal energies. Experimental results showed a clear correlation between light intensity and syngas yield, with a CO2 conversion rate of 6.35% achieved after 3 hours of simulated sunlight illumination. Photoelectrochemical measurements and simulations also demonstrated the better separation and transport of photoexcited carriers in Au/TiO2 compared to TiO2, thanks to localized surface plasmon resonance that heats the nanocatalysts under concentrated full-spectrum irradiation. In situ diffuse reflectance infrared Fourier transform spectroscopy analysis further suggested that the photothermal effect accelerates the formation of intermediates and enhances the overall photocatalytic rate.

Summary: Photocatalytic CO2 reduction using renewable solar energy is a promising strategy for managing global carbon balance. However, the process of oriented photogenerated electron delivery is challenging. In this study, we developed a method to construct porous nitrogen-doped carbon nano-fibers loaded with highly dispersed nickel and molybdenum phosphide nanoparticles for efficient CO2 reduction. The porous carbon nanofibers improved charge/mass transfer and CO2 adsorption, while the highly dispersed nickel species stabilized by coordinating Ni-N bonds with N from the carbon nanofibers adjusted the material's band structure and altered the transfer route of the photogenerated carriers. The resulting Ni-MoP@NCPF exhibited high CO product selectivity and rate under visible light irradiation, outperforming the Ni-free MoP@NCPF. These findings provide new insights into cost-effective transition metal compounds for photocatalytic CO2 reduction through morphology, composition, and heterointerface engineering.

Summary: Zero-dimensional (0D) organic metal halide hybrids (OMHHs) are a new class of light emitting materials with exceptional color tunability. However, their application as emitters for electrically driven light emitting diodes (LEDs) is challenging due to the low conductivity of wide bandgap organic cations. In this study, a new OMHH, triphenyl(9-phenyl-9H-carbazol-3-yl) phosphonium antimony bromide (TPPcarzSbBr(4)), is developed as an efficient emitter for LEDs. Red LEDs fabricated with TPPcarzSbBr(4) thin films as the light emitting layer exhibit the highest reported external quantum efficiency (EQE), peak luminance, and current efficiency among 0D OMHH-based electroluminescence devices.

Summary: Intermolecular interactions on inorganic substrates significantly affect the electrochemical and photophysical properties of materials in hybrid electronics. Control of these interactions is essential for intentional formation or inhibition of processes on a surface. This study demonstrates the influence of surface loading and atomic-layer-deposited Al2O3 overlayers on the intermolecular interactions of a ZrO2-bound anthracene derivative, as observed through photophysical properties. The addition of ALD overlayers decreases excimer formation, but excimer features still dominate in the emission and transient absorption spectra.

Summary: In spring 2020, the chemical education community faced a sudden transition to online classes and assessments. This study examines the impact of online exams on assessment quality and student performance in a General Chemistry II class. The results indicate that the quality of exams and student performance remained consistent regardless of in-person or online administration, and there was no evidence of increased cheating in online exams compared to in-person exams. Although these findings cannot be universally applied, they suggest that concerns about cheating in unproctored online exams may not be valid.
