Development and Mechanistic Studies of Ternary Nanocomposites for Hydrogen Production from Water Splitting to Yield Sustainable/Green Energy and Environmental Remediation

Asim Jilani et al.

Summary: Photocatalysts play a crucial role in water treatment and hydrogen production. This study focuses on the photocatalytic degradation of CIP and H-2 production using novel silver-nanoparticle ternary-nanocomposites. The optimized ratio of thiolated reduce-graphene oxide in the nanocomposites enhances activity by increasing charge carriers' movements and reducing charge-recombination ratios. Under optimized conditions, AgNPs-S-rGO(2%)@g-C3N4 shows a CIP degradation rate of 95.90%. The chemical and morphological analysis supports the role of thiolation in this enhancement, assisted by the surface plasmon resonance of AgNPs. The proposed mechanism involves the photo-excited electrons reacting with water moieties to generate H-2.

Stacking-Mediated Type-I/Type-II Transition in Two-Dimensional MoTe2/PtS2 Heterostructure: A First-Principles Simulation

Kai Ren et al.

Summary: In this study, the electronic characteristics and properties of a MoTe2/PtS2 van der Waals heterostructure (vdWH) were investigated through density functional calculations. The study found that the stacking structures of the heterostructure have a significant impact on the band structure, and proposed suitable stacking configurations for both photocatalytic and light-emitting device applications. The band alignment and potential drop were also studied to prevent charge recombination, and the heterostructure showed excellent optical absorption capacity in the visible wavelength range. The research provides a theoretical guide for designing and controlling 2D heterostructures for photocatalytic and photovoltaic devices.

Diethylenetriamine synergistic boosting photocatalytic performance with porous g-C3N4/CdS-diethylenetriamine 2D/2D S-scheme heterojunction

Xing Chen et al.

Summary: In this study, a series of heterostructure photocatalysts of 2D/2D porous graphitic C3N4/CdS-diethylenetriamine (DETA) nanocomposites were designed for photocatalytic hydrogen production, with improved performance attributed to factors such as increased active sites from Pg-C3N4, faster interfacial charge separation and transfer in the 2D/2D heterojunction, and synergistic enhancement from DETA. The experimental results demonstrated significantly higher hydrogen evolution activity compared to individual CdS-DETA and Pg-C3N4, indicating the potential of this novel heterojunction design for application in photocatalysis.

High dielectric constant of NiFe2O4-LaFeO3 nanocomposite: Interfacial conduction and dielectric loss

C. Jesica Anjeline et al.

Summary: In this study, a nanocomposite of NiFe2O4 and LaFeO3 was synthesized via a sol-gel method, with the ratio of 1:2 of NiFe2O4-LaFeO3 exhibiting a high dielectric constant of 10390 at 1 kHz. The high dielectric constant and loss were attributed to the Maxwell-Wagner type space charge polarization arising from the microstructure that consists of large and continuous grain boundaries, and the conducting phase at the interface, respectively.
