“…EXAFS can also detect the Chemical forms information of metal elements by oscillating in the EXAFS region ( Hu et al., 2020 ). Compared to EXAFS, XANES exhibits characteristics such as subtle structural changes, a shorter acquisition time, high sensitivity to information like valence states, and faster identification of chemical types and forms of elements ( Hara et al., 2023 ; Ren et al., 2023 ). XAS requires low sample amounts, does not damage the sample, and provides information on coordination atom types, coordination numbers, and atomic spacing.…”

Heavy metal (HM)-induced stress can lead to the enrichment of HMs in plants thereby threatening people’s lives and health via the food chain. For this reason, there is an urgent need for some reliable and practical techniques to detect and analyze the absorption, distribution, accumulation, chemical form, and transport of HMs in plants for reducing or regulating HM content. Not only does it help to explore the mechanism of plant HM response, but it also holds significant importance for cultivating plants with low levels of HMs. Even though this field has garnered significant attention recently, only minority researchers have systematically summarized the different methods of analysis. This paper outlines the detection and analysis techniques applied in recent years for determining HM concentration in plants, such as inductively coupled plasma mass spectrometry (ICP-MS), atomic absorption spectrometry (AAS), atomic fluorescence spectrometry (AFS), X-ray absorption spectroscopy (XAS), X-ray fluorescence spectrometry (XRF), laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS), non-invasive micro-test technology (NMT) and omics and molecular biology approaches. They can detect the chemical forms, spatial distribution, uptake and transport of HMs in plants. For this paper, the principles behind these techniques are clarified, their advantages and disadvantages are highlighted, their applications are explored, and guidance for selecting the appropriate methods to study HMs in plants is provided for later research. It is also expected to promote the innovation and development of HM-detection technologies and offer ideas for future research concerning HM accumulation in plants.

“…These have been discussed in previous p-ZnO reviews. 64,65 Among them, oxygen vacancy (V O ) is a type of donor defect that needs to be focused on in the study of p-type ZnO because of its compensating effect on the acceptor. Oba et al 66 calculated the forming energies and thermodynamic transition levels of the O vacancy (V O ), the Zn interstitial at the octahedral site (Zn i ), the Zn antisite (Zn O ), and the Zn vacancy (V Zn ) in ZnO by first principle computational studies as shown in Figure 6a,b.…”

ZnO is a significant semiconductor material with the characteristics of direct band gap, large exciton binding energy, and easy growth of high-quality nanostructures, and it is widely used in various fields. However, obtaining high-quality p-type ZnO has become a significant obstacle to the wide application of ZnO. The research on p-ZnO started several decades ago and is regarded as the research focus. Many researchers have obtained high-quality p-ZnO by chemical vapor deposition (CVD) and physical vapor deposition (PVD). To obtain high-quality p-ZnO, researchers have used some “better” techniques to improve the crystal quality and mobility of p-ZnO, such as molecular beam epitaxy (MBE) and post-treatment. This review provides an overview of some methods for obtaining high-quality p-ZnO, such as increasing the acceptor concentration, shallowing acceptor energy levels, and reducing donor defects. In addition, we also review the applications of p-ZnO in LEDs, UV detectors, thin-film transistors, gas sensing, bionic materials, and other fields.

Photocatalysis and electrocatalysis have emerged as promising technologies for addressing the energy crisis and environmental issues. However, the widespread application of these technologies is hampered by the challenge of scaling up the production of photo/electrocatalysts that are not only highly active and stable but also cost‐effective and environmentally benign. This review delves into the latest advancements in the large‐scale synthesis of photo/electrocatalysts. The factors to be considered in the large‐scale production of catalysts are discussed first. The synthesis methods for batch preparation of photo/electrocatalysts are then comprehensively introduced, with a thorough discussion of their respective advantages and limitations. Moreover, the data analysis via machine learning techniques, which not only accelerates the identification and refinement of potential new catalysts but also offers insights for enhancing the high‐throughput synthesis of catalysts, is introduced in detail. Then the representative examples are presented to illustrate the applications of large‐scale catalysts in the field of industrial‐level photo/electrocatalysis. Finally, the challenges and prospects in the development of large‐scale production of photo/electrocatalysts are discussed. By bridging the gap between laboratory research and industrial application, this review aims to provide a reference for the future of large‐scale preparation of photo/electrocatalysts in sustainable energy conversion and beyond.
