Summary: We present a perovskite single-phototransistor visible-light spectrometer based on deep-learning. The spectrometer size matches that of the phototransistor. A deep-learning system is trained using characteristic parameters of visible-light wavelength, gate voltage, and power densities to learn a photoresponsivity matrix. Unknown spectra can be reconstructed using the corresponding photocurrent vectors. In our confirmatory experiment, we successfully reconstructed a 532-nm laser and a multipeak broadband spectrum using our perovskite single-phototransistor spectrometer. By increasing the number of sampling points from 80 to 400, the resolution is improved to 1nm. Increasing the number of sampling points, characteristic parameters, and training datasets provides a way to further improve the resolution. Additionally, this research suggests that artificial intelligence technology could pave the way for on-chip visible-light spectroscopy.

Summary: This study presents the synthesis and photocatalytic activity of cubic-shaped monoclinic scheelite BiVO4 nanocrystals with coexposed {0 1 0}/{1 1 0} facets through a template-free method at low temperature. The optimized nanocrystals exhibited excellent photocatalytic efficiency in degrading methyl orange and diazinon under solar light irradiation. This enhancement in photocatalytic activity is attributed to the formation of surface heterojunctions between the coexposed {0 1 0} and {1 1 0} facets, which facilitates charge transfer and separation.

Summary: In this study, we synthesized Sb-based single crystals of Cs2AgSbCl6 with a low bandgap of approximately 1.82 eV and investigated the effect of strain on their optical properties. Interestingly, the polycrystalline ground powder and heated single crystals showed a larger bandgap of about 2.55 eV. The reduction in bandgap is attributed to the presence of strain in the single crystals, which was confirmed by X-ray diffraction and Raman spectroscopy and supported by density functional theory calculations. Strain engineering for bandgap reduction could be crucial for the development of environmentally friendly solar cells with low bandgaps.

Summary: In this study, the effect of ionic liquids with cations on the performance of perovskite solar cells (PSCs) was examined. By controlling the amount of cations introduced, lattice microstrains were minimized and the crystal structure's growth and stability were promoted. Furthermore, adding organic anions helped passivate grain boundaries and inhibit non-radiative processes, leading to further improvements in device performance. The incorporation of ionic-liquid dopants into the perovskite material resulted in the creation of devices with an efficiency of 22.74%. Additionally, these devices retained their initial efficiency of 91% for 1000 hours under conditions of 65 +/- 5% relative humidity.

Summary: The formation of a uniform mesoporous CdS shell on the surface of Sb2S3 nanorods (NRs) via a surface cationic displacement strategy constructs the core-shell Sb2S3@CdS heterojunction with high BET surface area and excellent near-infrared light harvesting capacity. The Sb-S-Cd bonding interaction and van der Waals force significantly enhance the stability and synergy of Sb2S3/CdS heterointerface throughout the entire surface of Sb2S3 NRs, promoting the Sb2S3-to-CdS electron transfer due to the formation of built-in electric field. Therefore, the optimized Sb2S3@CdS catalyst achieves highly enhanced simulated sunlight-driven Cr(VI) reduction and decomplexation of complexed Cr(III), resulting in effective chromium-containing wastewater treatment.

Summary: A sub-bituminous natural coal sample was modified with sulfuric acid and nitric acid to enhance its adsorption capacity for ciprofloxacin antibiotic residuals in water. The modifications resulted in increased surface area and the incorporation of new chemical groups into the coal structure. The adsorption capacities of the modified samples were significantly higher than the original sample, with the sulfuric acid modification showing the highest adsorption capacity. The adsorption of ciprofloxacin by the modified samples was mainly driven by physical forces, and the thermodynamic analysis indicated that the uptake of ciprofloxacin was spontaneous and endothermic.

Summary: Single-atom Nb anchored on g-C3N4 showed enhanced photocatalytic performance, attributed to the formation of Nb-C bonds and N defects. The anchoring of single-atom Nb promoted the formation of N defects in g-C3N4, which accelerated the directional transfer of photogenerated charge carriers. Additionally, N defects acted as active centers for photocatalytic reactions. This study emphasizes the importance of the synergistic effect of anchoring Nb and generating N defects for developing advanced g-C3N4-based photocatalysts.
