A Z-scheme charge transfer pathway was realized at the interface of CdS/PDI heterojunction by in situ growth nanocrystalline CdS on surface perylene diimide (PDI), resulting increased photocatalytic O 2 evolution activity.
Abstract It is still a challenge to develop an organic conjugated photocatalyst with high O 2 evolution rate. Functionalization polymer photocatalysts effective way enhance photocatalytic performance. In this study, series of perylene imide polymers (PDIs) are prepared by introducing different number phenyl groups at bay position PDI, and the influence substituents on charge separation activity investigated. reveals that monosubstituted PDI exhibits highest rate 2524.88 µmol g –1 h under...
Poly(vinylidene fluoride) (PVDF) is a well-known polymer with (−CH2–CF2−)n chemical formula that used, in particular, electronic devices. The spatial arrangements of −CH2– and −CF2– units the alignment PVDF chains determine ferroelectricity, pyroelectricity, piezoelectricity condensed-phase PVDF. can be fabricated Al metal as an energetic composite for rocket propellants.

A fully interactive Cu/C/H/O reactive force field (ReaxFF) was developed for the Cu-metal surface catalysis system following three steps: (1) re-optimization of Cu by an extended training set including additional cluster properties, (2) combination this re-optimized and existing C/H/O field, (3) fitting interactions between with extensive DFT data involving various binding energies elementary reaction steps. In addition, we algorithm to search transition state (TS) steps, which is first TS...
Abstract Cocatalyst plays an important role in efficient charge transfer and separation for photocatalysis. Herein, a MoS 2 /CdS photocatalyst with as cocatalyst was designed by using Mo‐MOF Cd‐MOF precursors. Due to the existence of rich sulfur vacancies 1T phase, shows strong capture transport ability. The photo‐generated electrons on conduction band (CB) can be bound vacancy CdS effectively transported through compact interface between nanoparticles 2D large‐scale . optimal 1 %MoS...
Molecular insights into graphene-catalyst surface interactions can provide useful information for the efficient design of copper current collectors with graphitic anode interfaces. As graphene bending affect local electron density, it should reflect its reactivity as well. Using ReaxFF reactive molecular simulations, we have investigated possible in vacuum and near surfaces. We describe energy cost binding hydrogen two different parameter sets, demonstrating relevance using more recently...
The performance of lithium-ion batteries largely depends on the stability solid electrolyte interphase (SEI) layer formed anode surface. Strategies to improve SEI robustness often rely optimizing its composition through electrolytic additives. Recently, amalgamation fluorinated cosolvents with nitride sources as additives has been shown enable construction sustainable fluorinated-nitrided layers (FN-SEI). Furthermore, presence lithiophilic nitrides embedded in lithium fluoride (LiF) was...
Ever since the discovery of graphene and subsequent explosion interest in single-atom-thick materials, studying their mechanical properties has been an active area research. Atomistic length scales often necessitate a rethinking physical laws, making such studies crucial for understanding ultimately utilizing material properties. Here, we report on investigation nanoscale periodic ripples suspended, single-layer sheets by scanning tunneling microscopy atomistic scale simulations. Unlike...
Rainbow holographic image resolution, primary aberrations, and bandwidth requirements are presented. The results obtained for the rainbow process rather general, which conventional requirements, can be derived. conditions elimination of five aberrations also given. These may useful application obtaining a high-quality hologram image. In terms we have shown that requirement construction is usually several orders lower than process. Therefore, lower-resolution recording medium generally used...
Solar water splitting is an eco-friendly technology to produce clean energy, but the oxidation half reaction hinders overall due four electron transfer processes. Z-Scheme photocatalytic system could effectively promote separation of photogenerated carriers and keep strong redox ability. However, date, research on heterojunction material for oxygen evolution very limited, mechanism enhancing activity has never been studied in detail. In this work, first time CdS/PDI Z-scheme with high O 2...
