Construction of MoS2 nanoparticles incorporated TiO2 nanosheets heterojunction photocatalyst for enhanced visible light driven hydrogen production

B. Anandha Priya et al.

Summary: In this study, a high-performance MoS2/TiO2 heterostructure nanocomposite was prepared by selectively depositing MoS2 nanoparticles on the surface of TiO2 nanocrystals. The material exhibited a high hydrogen evolution rate under visible light, which was mainly attributed to the synergistic effect between MoS2 and TiO2, accelerating charge separation and transfer.

Boron-Cobalt-Nickel-Yttrium nanocatalysts for hydrogen production from the hydrolysis of alkaline sodium borohydride solution

Saeideh Kord et al.

Summary: In this study, the four-component nanostructures of boron-cobalt-nickel-yttrium (B-Co-Ni-Y) were synthesized and characterized. The 1:1:1:2 atomic ratio was found to be the best catalyst based on catalytic performance evaluation. The affected parameters were optimized, leading to the highest hydrogen production and activation energy value. The proposed nanocatalyst showed stability during 5 sequential cycles with a slight loss of activity.

Delving into role of palladium nanoparticles-decorated graphene oxide sheets on photoelectrochemical enhancement of porous silicon

Elahe Bolhasani et al.

Summary: Two different photocathodes based on porous silicon were fabricated and fully characterized in this study, with the PS/GO/Pd photocathode showing significantly higher photocurrent density compared to PS/rGO-Pd, attributed to the lower charge transfer resistance at the PS/GO and rGO/Pd interfaces. The mechanism of enhancement is believed to be due to well-alignment in electron bands and positive synergetic effect between the components, leading to improved utilization of photo-induced charge carriers for desired reactions.

Insight into energy level modulation via Mn doping solid solutions for enhanced photocatalytic hydrogen production

Huijuan Yang et al.

Summary: The modulation of energy levels in sulfide solid solutions through Mn doping was found to greatly enhance the separation efficiency of photogenerated electrons and holes, resulting in a significant increase in hydrogen production rate under visible light irradiation. This improvement was attributed to the creation of an impurity band, narrow band gap, and negative conduction band after Mn doping, providing valuable insight into the mechanism of enhanced photocatalytic activity through doping strategies.

Summary: Photocatalytic conversion of carbon dioxide into fuels and chemicals is a promising method for carbon neutralization. Researchers have discovered that doping oxygen into the ultrathin structure of g-C3N4 can improve the efficiency of CO2 reduction. Additionally, density functional theory calculations have shown that oxygen doping introduces new impurity energy levels, making electrons easier to be excited and enhancing the catalyst's performance.

Summary: This study demonstrates that surface chemisorbed ambient moisture can lead to highly selective response of zinc oxide nanoparticles to hydrogen gas at room temperature. The presence of p-type NiO quasi-nanowires in conjunction with n-type ZnO nanoparticles significantly enhances the response to hydrogen gas. Furthermore, the presence of heterojunction barriers and surface ionic conduction at the NiO-ZnO interface synergistically enhance the selective response to hydrogen gas at room temperature.
