Harnessing photo/electro-catalytic activityvianano-junctions in ternary nanocomposites for clean energy

Abstract

Though the availability of solar energy is predicted for centuries, the diurnal and asymmetrical nature of the sun across the globe presents significant challenges in terms of harvesting sunlight. Photo/electro-catalysis,...

Surface plasmon-driven photocatalytic activity of Ni@NiO/NiCO3 core–shell nanostructures

“…52,53 In particular, the redox potential of the CO 3 c À /CO be used in water oxidation processes, the conrmation of which requires more advanced (in situ/operando) studies. 13 Based on the XPS results, the ratio of NiCO 3 /NiO for pristine sample is lower than that of N70-100/2 h. Thus, the sample N70-100/2 h has the highest amount of amorphous NiCO 3 and shows the highest H 2 generation.…”

“…However, even aer the intensive efforts throughout the world, this energy source remains a mirage due to the less efficient H 2 evolution reaction (HER), which necessitates continual work in this eld. 13 It is well known that the morphology of the homogenous or heterogenous catalysts affect the overall photocatalytic activity. 14,15 For example, the core-shell structure of the heterogenous nanocomposites that consists of an inner core material surrounded by a shell material, with different structural and/or compositional features and dimensions at the nano-scale have attracted remarkable attention and become a signicant research area in the eld of nanotechnology.…”

Bismuth-Graphene Nanohybrids: Synthesis, Reaction Mechanisms, and Photocatalytic Applications—A Review

“…A positive synergetic effect between the graphene sheets and MoS 2 is believed to occur. The cocatalyst components on photodegradation can efficiently improve the interfacial charge transfer, suppress the recombination of charges, and offer many photocatalytic reaction centers and active absorption sites [186]. The BWO/MG ternary hybrid facility is a visible and inexpensive environmental photocatalyst that expands the composite photocatalyst preparation range of MG hybrids and provides a prospective way to improve the performance of photocatalysts.…”

Physical mechanisms of photoinduced charge transfer in neutral and charged donor–acceptor systems

“…Photoinduced charge transfer is one of the most crucial issues in the elds of biology, material science and chemistry. [1][2][3][4][5] To better understand the processes of photoinduced charge transfer, revealing the physical mechanisms of photoinduced charge transfer is required in neutral and charged donoracceptor systems; [1][2][3] for example, the electron-hole redistribution aer excitation 6 and the electron-hole coherence 7 in the dynamic process of charge transfer. In this paper, we report visualization methods to visually reveal the physical mechanisms of photoinduced charge transfer in neutral and charged donor-acceptor systems of poly[2,1,3-benzothiadiazole-4,7-diyl [4,4-…”
