Electrocatalytic denitrification is considered as the most promising technology to transform nitrates nitrogen gas in sewage so far. Although noble metal-based catalysts a cathode material have reached decent removal capacity of nitrate, high cost main hamper electrocatalytic reduction. Therefore, development alternative catalysis toward highly effective imperative yet still remains significant challenge. Herein, corchorifolius-like structure, where Fe nanoparticles are sealed carbon...
Abstract Electrochemical conversion of carbon dioxide into fuel and chemicals with added value represents an appealing approach to reduce the greenhouse effect realize a carbon-neutral cycle, which has great potential in mitigating global warming effectively storing renewable energy. The electrochemical CO 2 reduction reaction (CO RR) usually involves multiproton coupling multielectron transfer aqueous electrolytes form multicarbon products (C 2+ products), but it competes hydrogen evolution...
Abstract Three-dimensional superlattices consisting of nanoparticles represent a new class condensed materials with collective properties arising from coupling interactions between close-packed nanoparticles. Despite recent advances in self-assembly nanoparticle superlattices, the constituent have been limited to those that are attainable as monodisperse In addition, self-assembled generally weakly coupled due surface-coating ligands. Here we report fabrication three-dimensionally...
Self-assembled nanocrystal (NC) superlattices are emerging as an important class of materials with rationally modulated properties. Engineering the nanoscale structure constituent building blocks well mesoscale morphology NC is a crucial step in widening their range applications. Here, we report template-assisted epitaxial assembly strategy, enabling growth freestanding, carbon-coated tubular monolayer (TMSLs). Specifically, design and construct TMSLs hollow Mn3O4 NCs (h-Mn3O4-TMSLs) by...
Abstract While great progress has been achieved in the synthesis of ordered mesoporous carbons past decade, it still remains a challenge to prepare highly graphitic frameworks with mesoporosity and high surface area.

The MGFs possess face‐centered‐cubic symmetry interconnected...
Transition-metal sulfides as late-model electrocatalysts usually remain inactive in lithium-sulfur (Li-S) batteries spite of their advantages to accelerate the rapid conversion lithium polysulfides (LiPSs). Herein, a series cobalt-doped vanadium tetrasulfide/reduced graphene oxide (x%Co-VS4/rGO) composites with an ultrathin layered structure active sulfur-host material are prepared by one-pot hydrothermal method. The well-designed two-dimensional 3%Co-VS4/rGO heteroatom architecture defects...
An oxidative nucleophilic cyclization of 2-alkynylanilines with thiophenols under metal-free conditions was developed. The one-pot two-step reaction involves a PhI(OAc)2-mediated dearomatization and Brønsted acid promoted cyclization. DFT calculations were performed to understand the pathway.
In this paper, a static load test and multiparameter statistical analysis method are used to study the value of pile side friction in different soil layers loess region. Currently, testing is most commonly determine bearing capacity foundation. During test, vertical applied at top pile, data under each level recorded, Q‐S curve drawn obtain ultimate single pile. Reinforcement stress gauges installed sections body, then axial force section calculated. Few studies have investigated calculation...
Surface-enhanced Raman scattering (SERS) offers significant advantages for single-molecule detection. However, stochastic molecular motion makes it challenging to consistently capture signals from binding events, particularly in complex environments. Herein, we propose a novel SERS system via the pore nanoconfinement effect of covalent organic frameworks (COFs) achieve reliable The self-assembled COF thin films on metal substrates (Au/Ag) create nanogap 3 nm, allowing electric field...
