Fe-doped Ni (oxy)hydroxide shows intriguing activity toward oxygen evolution reaction (OER) in alkaline solution, yet it remains challenging to further boost its performance. In this work, a ferric/molybdate (Fe3+ /MoO42- ) co-doping strategy is reported promote the OER of oxyhydroxide. The reinforced Fe/Mo-doped oxyhydroxide catalyst supported by nickel foam (p-NiFeMo/NF) synthesized via unique plasma etching-electrochemical doping route, which precursor Ni(OH)2 nanosheets are first etched...
Quantum dots/graphene (QDs/GR) composite materials show a distinct synergistic effect between the QDs and graphene, which has aroused vast attention toward their unique characteristics in last few decades.
Abstract Using a unique data set of firms listed on China’s Shenzhen Stock Exchange, we show that investors’ corporate site visits convey information about future stock returns. Firms with abnormally frequent investor predictably outperform infrequent by approximately 70-to-100 basis points per month. This return predictability concentrates neglected low trading volumes and when investors incur higher travel costs. Abnormally accompany increased holdings among visiting institutions predict...
Due to the increasing and rapid economic population growth over past years, urban areas have become focus of carbon-emission-reduction policies. Meanwhile, they are also continuously subjected environmental pressure from development. Therefore, this study used STIRPAT model develop an index capture development based on a panel dataset 284 prefecture cities 2006 2022 in mainland China. Subsequently, fixed effect quantile regression were test impact level carbon emissions. The results showed...
In this article, we fabricated Y2Ti2O7: Yb, Er, Tm upconversion inverse opal photonic crystals with energy transfer between Er3+ and Tm3+, investigated the influence of band gap on Tm3+ Er3+. It is interesting that strong modification steady state emission spectra observed, green or red from was suppressed in opal. More significantly, enhanced by suppression Er3+, thus blue considerably improved opals. Additionally, mechanisms for are discussed. We believe present work will be valuable...
The key for fabricating efficient organic/n‐Si planar heterojunction solar cells is the organic semiconductor layer, which governs steps in photocarrier harvesting such as charge carrier separation and extraction. Typical semiconductors, however, are inadequate to yield good device performance due their low electrical conductivities undesirable work functions. Herein, a method proposed boost concentration poly(3,4‐ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) from 10 18 22 cm −3...
Different dynamics of excitons and free carriers in 2D Ruddlesden–Popper halide perovskites with layer numbers <italic>n</italic> = 1 ≥ 2.
The integration of highly luminescent CsPbBr3 quantum dots on nanowire waveguides has enormous potential applications in nanophotonics, optical sensing, and communications. On the other hand, CsPb2 Br5 nanowires have also attracted a lot attention due to their unique water stability controversial property. Here, growth nanocrystals is reported first by simply immersing powder into pure water, CsPbBr3-γ Xγ (X = Cl, I) Br5-γ are then synthesized for tunable light sources. Systematic structure...
Metal halide perovskites (MHPs) have demonstrated great advances for photovoltaic and optoelectronic applications. However, owing to the presence of synergy from lattice strain, defects MHPs, environment, MHPs suffer phase transitions degradation, resulting in restriction their practical applications further commercialization. Multiple metal elements can coexist form alloys due high tolerance composition replaceability, which provides a novel strategy improvement performance stability. In...
Abstract Solar cells formed by spin‐coating organic absorber layers on silicon have attracted widespread attention due to their simple processes and high photovoltaic conversion efficiency (PCE). In typical organic/Si solar cells, however, surface defects or unsatisfactory carrier separation are inadequate yield excellent device performance. Here, the Au@MoS 2 nanocomposites well synthesized doped into layer of poly (3,4‐ethylenedioxythiophene)/polystyrene sulfonate (PEDOT:PSS) improve its...
