“…Since, the discovery of graphene, 14–17 two-dimensional (2D) materials have also been given much attention, and a number of monolayers have been reported. 18–24 Moreover, many of them were identified as being suitable photocatalytic materials for HER, and an example of such a material is antimonene nanoribbon with halogen edge passivation. 25 However, the solar-energy-to-hydrogen conversion efficiency ( η ) is not satisfactory because of mutual constraints between the optical absorption and the redox potential of the band energy edges.…”

“…The E g ’s of BiOBr, CDs/BiOBr, N-CDs/BiOBr, and Bi-N-CDs/BiOBr were estimated through a Tauc plot, corresponding to 2.66, 2.48, 2.36, and 2.25 eV, respectively (Figure c). The narrower band gap suggests the stronger visible-light responsiveness, which may bring about more e – –h + pairs, thereby enhancing the photocatalytic efficiency . A Mott–Schottky (M–S) test was conducted to explore the band structure of BiOBr.…”

The opacity, fragility, and environmental unfriendliness of the traditional photocatalytic matrix cannot fully utilize the properties of photocatalysts and efficiently degrade pollutants. In this work, a transparent wood hydrogel with a core–shell structure was developed using transparent wood (TW) impregnated with polyacrylic acid (PAA) as the core layer and Bi-N-carbon dots/BiOBr (Bi-N-CDs/BiOBr) photocatalyst-initiated polymerization of acrylic acid (AA) monomers as the shell layer. In the shell layer, nanoscale CDs with rich hydrophilic groups built a link between BiOBr and PAA and strengthened the adsorption–photocatalysis synergistic removal for RhB. The original wood backbone well conserved during preparation led to an anisotropic structure in the resultant Bi-N-CDs/BiOBr@TW photocatalytic wood hydrogel. Namely, after introducing Bi-N-CDs/BiOBr as the linker and reinforcing agent, the tensile strength was up to 3.2 and 11.03 MPa along the radial (R-) and axial (A-) directions, which was 1.6- and 1.06-fold of R-TW and A-TW, respectively. Hence, Bi-N-CDs/BiOBr@TW with high strength furnishes multiple separations and reutilizations, and the RhB removal rate is approximately 85% after five cycles. The Bi-N-CDs/BiOBr@TW exhibited light transmittance up to 64.6 and 52.3% at 800 nm along the R- and A-directions, respectively. Moreover, the adsorption–photocatalysis synergistic rate of Bi-N-CDs/BiOBr@TW reached 93% in 300 min at pH = 7. This paper offers a strategy for fabricating wood hydrogels with outstanding stretchability, transparency, dye removal efficiency, and recyclability, opening a significant route for alleviating dye pollution.

“…Although the standard DFT is known to underestimate band gaps which is usually corrected by hybrid functionals [38][39][40][41], Li et al [34] found only a tiny difference (that will not affect the conclusions) between the SBHs calculated using PBE and HSE06. The authors of this study further concluded that PBE-D2 method is able to provide sufficiently reliable results and the HSE06 method is no longer considered in their discussion.…”

In this study, we made the graphene contact with monolayer MoSSe in two ways as G/SMoSe and G/SeMoS after which the electronic properties, Schottky contact, and barrier height were obtained for both contact sides. An n-type Schottky contact was observed for both structures with reasonable SBH. To further investigate the contact type and barrier height as a function of layer thickness, bilayers of the Janus MoSSe were verti-
