“…In addition, MoS 2 has excellent light absorption, photothermal properties, and reduction abilities [ 26 , 27 ]. The WO 3 and MoS 2 energy band structures match well, which is in line with the design mechanism of heterojunctions in a Z-scheme system [ 28 ]. Using the built-in electric field between WO 3 and MoS 2 , photogenerated carriers can be effectively separated, thus enhancing the removal of pollutants.…”

“…Thus, the path of charge carrier transfer in heterojunction photocatalysts can be determined by this shift in binding energy. 63 Upon combining g-C 3 N 4 with o-Cu 2 O, the binding energy between the C and N elements moved positively, which implies the electron cloud density of g-C 3 N 4 has fallen, suggesting that g-C 3 N 4 has lost electrons. Conversely, the negative movement in the binding energy between O and Cu elements reflects an enhancement in electron cloud density in o-Cu 2 O, signifying electron gain.…”

Optimizing the photocatalytic efficiency of semiconductor materials is capable of being achievable by the effective tuning of the interfacial transport efficiency of photogenerated carriers utilizing crystal facet engineering. This study adopted a liquid deposition routine tackle to generate cubic, truncated octahedral, and octahedral Cu 2 O crystals with various exposed facets. Afterward, a Cu 2 O/g-C 3 N 4 heterojunction was constructed exploiting defective g-C 3 N 4 as a carrier. By controlling the exposed facet, the work function difference between Cu 2 O and g-C 3 N 4 was adjusted, resulting in an enhanced built-in electric field and greater photogenerated carrier transit via the Cu 2 O/g-C 3 N 4 heterojunction interface. The OCN heterojunction, which is composed of g-C 3 N 4 and octahedral Cu 2 O with a {111} facet, revealed the highest photocatalytic degradation effectiveness of tetracycline (90.8%), which exceeded the values of pure octahedral Cu 2 O and g-C 3 N 4 by 1.26 and 1.75 times, respectively, as determined by photocatalytic activity experiments. Z-scheme heterojunction among g-C 3 N 4 and octahedral Cu 2 O has been verified through UPS, XPS, EIS, and transient photocurrent response analysis, along the direction of the built-in electric field recognized between them. In contrast, OCN displayed the highest photocatalytic activity due to its Z-scheme heterojunction, which evidently promoted the separation efficiency of photogenerated carriers. This research proposes an innovative approach for regulating the exposed facet of semiconductors and augmenting the inherent electric field strength of heterojunctions, culminating in the efficient photocatalytic degradation of tetracycline.

“…Previous studies have demonstrated that the incorporation of polydopamine into MXene significantly enhances the material's mechanical strength and environmental durability. [ 36 ] Figures S4, S7, and S8 (Supporting Information) show that LM is distributed throughout the aerogel in different ways, including the surface, coating, and wall‐hanging structures. Figure S9 (Supporting Information) shows the X‐ray diffraction (XRD) patterns of the MXene, LM, and PMLC.…”

As military power advances in the realm of information warfare, stealth technology has become a critical area of research for its effectiveness to evade detection. However, achieving high performance of compatible stealth across different functional mode bands remains a significant challenge. In this study, drawing inspiration from plant bionics, concepts of the directional freezing process are applied to develop a liquid metal‐MXene‐based hierarchical aerogel with radar‐infrared compatible camouflage. With a density of only 4.4 mg cm−3, the maximum reflection loss can reach −73.2 dB, and the absorption bandwidth can be adjusted up to 7 GHz. Following a thermal camouflage durability test, the sample successfully lowers the target's temperature from 400 to ≈160 °C. Remarkably, this temperature remains stable even after 180 days of exposure. Additionally, the material's ease of machining enables shape‐shifting camouflage capabilities, allowing objects to transform and resemble harmless items, thereby blending seamlessly with their surroundings. This breakthrough in compatibility performance signifies a substantial leap forward in multifunctional stealth technology development. It not only introduces innovative concepts, but also provides technical support, catalyzing further advancement in this field.
