“…Each TMD monolayer contains three atomic layers, forming an “X-M-X” sandwich structure. Adjacent monolayers are 6–7 Å apart and held together by weak van der Waals forces, which makes them easy to peel away [ 54 , 55 , 56 ]. Manganese sulfide, MnS, is a weakly magnetic semiconductor material of groups VIIB–VIA, with a band gap width of 3.7 eV.…”

Developing earth-abundant and highly effective electrocatalysts for electrocatalytic water splitting is a prerequisite for the upcoming hydrogen energy society. Recently, manganese-based materials have been one of the most promising candidates to replace noble metal catalysts due to their natural abundance, low cost, adjustable electronic properties, and excellent chemical stability. Although some achievements have been made in the past decades, their performance is still far lower than that of Pt. Therefore, further research is needed to improve the performance of manganese-based catalytic materials. In this review, we summarize the research progress on the application of manganese-based materials as catalysts for electrolytic water splitting. We first introduce the mechanism of electrocatalytic water decomposition using a manganese-based electrocatalyst. We then thoroughly discuss the optimization strategy used to enhance the catalytic activity of manganese-based electrocatalysts, including doping and defect engineering, interface engineering, and phase engineering. Finally, we present several future design opportunities for highly efficient manganese-based electrocatalysts.

Investigation of Optoelectronic Properties of HfClBr Janus Monolayer under the Biaxial Strain Effect

In general, the transition elements, including Hafnium (Hf), have become the focus of researchers' attention, as when they combine with chalcogens and halides, they turn into semiconductors with distinct energy gaps. Moreover, chalcogens and halides are desirable in scientific research when forming layers or membranes. The Janus monolayer is unique two-faced material composed of two different chemical species on opposite sides of a single layer. Herein, we use first-principles simulations to thoroughly investigate the electrical and optical properties of this material. Our calculations reveal that the Bromochlorohafnium (HfClBr) Janus monolayer is an indirect semiconductor at equilibrium, with an energy gap of 0.928 eV and changing from 0.532 eV to 1.233 eV after applying the biaxial strain, as determined by the Perdew-Burke-Ernzerhof (PBE) method. The results indicate that the Janus HfClBr monolayer has a competitive advantage over other materials for use in solar cells and energy storage devices due to its unique optical and electrical characteristics. Furthermore, our analysis showed that the optical and electrical characteristics of the Janus HfClBr monolayer are significantly impacted by biaxial strain, with the ability to absorb light in both the visible and ultraviolet spectral regions. Additionally, the first optical gap of the Janus HfClBr monolayer is found to be shiftable under the biaxial strain, suggesting potential applications in nano-electronics, particularly in the field of solar cells.

“…[1][2][3] However, the zeroenergy gap characteristic of graphene greatly limits its applications in electronics and optoelectronics. 4 Since then, on the one hand, researchers have been trying hard to open the band gap of graphene. [5][6][7][8] On the other hand, researchers have been seeking for new 2D materials with moderate band gaps.…”
