Sulfur vacancies-induced “Electron Bridge” in Ni4Mo/Sv-Zn Cd1-S regulates electron transfer for efficient H2-releasing photocatalysis

Cationic vacancies and interface engineering on crystalline–amorphous gamma-phase Ni–Co oxyhydroxides achieve ultrahigh mass/areal/volumetric energy density flexible all-solid-state asymmetric supercapacitor

“…The past decade has witnessed rapid development in the design and preparation of nanostructured transition-metalbased electrode materials with varied compositions/structures and defects. [12][13][14][15][16] Electrode materials with cationic vacancies or crystalline-amorphous interfaces can provide better electrochemical performance on account of their abundant defects/ distortions, electrochemical redox active sites and fast electron transfer, thus becoming an effective strategy for improving electrochemical properties. 17,18 In addition, metal cationic vacancy defects can be constructed by dissolving the corresponding anions.…”

Internal Interactions within the Complex Type-II Heterojunction of a Graphitic Carbon Nitride/Black Phosphorus Hybrid Decorated with Graphene Quantum Dots: Implications for Photooxidation Performance

“…With the recognition of photocatalysis as a sustainable solution, scientists have invested in a large number of endeavors in this field at a speedy pace. − Considering the sustainability of the catalysts and renewability of the energy source, heterogeneous photocatalysis has emerged as a highly green approach to removing pollutants from water. , Hitherto, the priority of an ideal photocatalyst has been set off as composed of earth-abundant elements and synthesized by using readily available cost-effective precursors along with possessing unique optical properties. To achieve such key properties, the architectural design of heterojunctions is a very prominent way to transform available solar light in existing nature into demanding energies. − Most of the efforts in the heterojunction design have been focused on the combination of two different semiconductors having different morphologies and band settings. Even though these materials have complemented synergistically one another and brought many advantages to the photocatalysis field, building a heterojunction consisting of more than two materials has been avoided due to the difficulties with their complex structures and synthetic procedures.…”

In situ annealing achieves an ultrafast synthesis of high coercive strontium ferrite foams and beyond

“…Permanent magnetic materials have attracted increasing attention because of their wide applications, such as in information storage, microwave devices, energy storage and conversion devices, catalysis, sensors, and biomedical science. [1][2][3][4][5][6][7][8][9][10][11] The commonly known permanent magnetic materials are SmCo 5 , Nd 2 Fe 14 B, L1 0 -FePt, and ferrites. [12][13][14][15][16][17] However, the complex preparation process, poor corrosion resistance, and high cost of permanent magnetic alloys restrict their large-scale applications.…”
