Photocatalysis has become a desirable technique to solve the current problems of environmental deterioration and energy shortage with its unique greenness. Perovskite-type rare-earth ferrites (ReFeO3) are visible light-responsive photocatalysts with high stability and tunable energy band structures. However, their severe charge recombination and small specific surface area limit their photocatalytic activity. The construction of perovskite-type rare-earth ferrite-based heterojunctions by introducing other semiconductors can improve their charge separation and enhance their photocatalytic activity. This article reviews the research progress of ReFeO3-based composite photocatalysts. Herein, the preparation methods for ReFeO3 and ReFeO3-based composites are first introduced. Next, the characterization means for evaluating their crystal morphology and structure, catalyst photoelectric properties and reaction mechanisms are summarized, and the latest applications of ReFeO3-based composite photocatalysts in the fields of environment and energy are systematically summarized based on the charge transfer mechanisms of different heterostructures. Finally, the current unsolved problems and future research directions are highlighted.

Optical Angle Barcodes Enabled by a Pixelated Metasurface for Absolute Micro-Angle Measurement

Efficient and ultra-sensitive measurements of micro-angle are critical technological requirements in various fields. Traditional measurement approaches have disadvantages in terms of accuracy and system complexity. Here, a micro-angle measurement scheme based on the pixelated metasurface is reported. By utilizing the interaction between a C-band optical frequency comb (OFC) laser source and the plasmonic metasurface, precise angle encoding is achieved, enabling each meta-pixel within the pixelated metasurface to exhibit ultra-sensitive responses to angular changes. Experimental results demonstrate a resolution as low as 2.8 mu rad for angle sensing. Furthermore, by controlling the dimensions of the meta-atom structural dimensions and designing specific combinations of meta-pixels, the unique angle response of individual pixels is manipulated, effectively creating an angle barcode. This technique allows for highly efficient acquisition of angle information, and based on this, it demonstrates absolute angle measurement with an average error at 7 mu rad. The robustness and stability of the proposed scheme is also evaluated. A pixelated metasurface based on a plasmonic structure is designed. By controlling the dimensions of meta-atom structures and designing specific combinations of meta-pixels, individual pixels can exhibit ultra-sensitive angular responses at mu rad level, thus creating angle-dependent optical barcodes. This work demonstrates absolute micro-angle measurements based on optical barcodes, highlighting the potential applications of meta-devices in precision pose measurement and sensing ***

Tailoring Phase Distribution of Quasi-2D Perovskites via Taurine-Assistance Enables Efficient Blue Light-Emitting Diodes

引用

SMALL 2024年第1期20卷 2304821-2304821页

作者： Qi, Zifu Yuan, Longfei Ding, Weigang Qin, Zhanpeng Wang, Shirong Liu, Hongli Li, Xianggao Tianjin Univ Sch Chem Engn & Technol Tianjin 300072 Peoples R China Collaborat Innovat Ctr Chem Sci & Engn Tianjin Tianjin 300072 Peoples R China

Quasi-2D (Q-2D) perovskites with typical varied n-phase structures deserve promising candidates in pursuing high-performance perovskite light-emitting diodes (PeLEDs). Whereas their weakness in precise n-phase distribution control disables the optical property of PeLEDs since the n = 1 phase is dominated by severe nonradiative recombination. Here, an effective phase distribution tailoring strategy is developed for pure blue PeLEDs by introducing taurine (TAU) into mixed halide Q-2D perovskites. The sulfonic acid group in TAU can coordinate with Pb2+ to suppress the formation of the n = 1 phase while promoting the growth of Q-2D perovskites into domains with the graded distribution of n = 2 and 3. The amino group in TAU forms hydrogen bonds with electronegative halide ions, suppressing the formation of halide vacancies and reducing the defect density in the Q-2D perovskite films. As a result, optimized blue Q-2D perovskite films boosted PLQY to 92%. Target blue PeLED was endowed with a peak EQE of 14.82% (average 12.6%) at 475 nm and a maximum luminance of 1937 cd m-2, which is among the reported high-level pure blue PeLEDs. This work demonstrates a feasible approach to regulate the phase distribution of Q-2D perovskites for high-performance blue PeLEDs. Taurine is employed to suppress the formation of the n = 1 phase and promote growth into domains with the graded distribution of n = 2 and 3 while reducing the defect density of blue Q-2D perovskites. Resultantly, the optimized blue PeLEDs with a peak EQE of 14.82% at 475 ***

The development and utilization of bulk resources provide the basic material needs for industrial systems. However, most current resource utilization patterns are unsustainable, with low efficiencies and high carbon emissions. Here, we report a quantitative tool for resource-based industries to facilitate sustainable and low-carbon transitions within the regional economy. To evaluate the effectiveness of this tool, the saline Qinghai Lake region was chosen as a case study. After optimizing the industrial structure, the benefits of economic output, resource efficiency, energy consumption, solid waste reduction, and carbon emission reduction can be obtained. The scenario analyses exhibit disparities in different transition paths, where the carbon mitigation, economic output, and resource efficiency that benefit from optimal development paths are significantly better than those of the traditional path, indicating the urgency of adopting cleaner technology and industrial symbiosis for regional industries. This study reports a quantitative tool for resource-based industries aimed at supporting sustainable, low-carbon regional transitions. The results provide optimal transition paths over traditional methods, highlighting the need for cleaner technology and industrial symbiosis.
