We report a strategy for the production of materials with structural hierarchy. The approach employs polymer microgels as templates synthesis semiconductor, metal, or magnetic nanoparticles (NPs). show that NPs predetermined dimensions and size-dependent properties can be synthesized by using very delicate balance between reaction conditions, composition structure microgel templates, concentration in microgel. Postheat treatment doped semiconductor reduces NP polydispersity allows control...
Systematic insights into the recent attainments, limitations, and future directions of hydrogen production, storage, delivery, usage are provided, aiming at offering critical guidance for establishment a society.
Metal hydrides (MHs) have recently been designed for hydrogen sensors, switchable mirrors, rechargeable batteries, and other energy-storage conversion-related applications. The demands of MHs, particular fast absorption/desorption kinetics, brought their sizes to nanoscale. However, the nanostructured MHs generally suffer from surface passivation low aggregation-resisting structural stability upon absorption/desorption. This study reports a novel strategy named microencapsulated...
Abstract Direct photocatalytic methane oxidation into value‐added oxygenates under mild conditions enables the sustainable chemical production but suffers from lack of active photocatalysts and overoxidation issue. Herein, defective ZnO nanoplates supported AuPd nanoparticles for efficient with O 2 as oxidant at room temperature are reported. A maximum liquid productivity 152.2 m g −1 h a selectivity 86.7%, more than half which is CH 3 OH, achieved over optimized AuPd/ZnO photocatalyst,...
The electrochromic mechanism in amorphous tungsten oxide films is studied using Raman scattering measurements. spectra of as-deposited show two strong peaks at 770 and 950 cm−1 due to vibrations the W6+–O W6+=O bonds, respectively, a weaker peak 220 that we attribute W4+–O bonds. When lithium or hydrogen ions electrons are inserted, extra W5+–O W5+=O bonds appear 330 450 cm−1, respectively. Comparison sputtered isotopic a-W16O3−y a-W18O3−y confirms these assignments. We conclude contain...

Metal nanocatalysis is an effective method to enhance the hydrogen storage properties of magnesium hydride (MgH2), and catalytic effect can be further improved by a matrix material supported nanometal. In this work, carbon nano-Ni (Ni@C) was synthesized calcination dimethylglyoxime dinickel chelate, then it doped into MgH2 improve de/rehydrogenation kinetics. This shows that homogeneously distributed Ni with refined particle size in base leads superior effects on absorption/desorption MgH2-5...
Electrocatalytic reduction of CO2 to formate is an attractive avenue for utilization. Unfortunately, existing catalysts suffer from low faradic efficiency production at high current density. Here, we report a general strategy preparing the Bi2O2CO3 nanosheet (BOC-NS) with abundant oxygen vacancies through in situ electrically driven conversion BiPO4 precursor. The converted BOC-NS displays (FEHCOO−) (∼100%) over wide potential region H-type cell and achieves partial density −930 mA cm−2...
For the first time, few-layer Ti3C2Tx (FL-Ti3C2Tx) supporting highly dispersed nano-Ni particles with an interconnected and interlaced structure was elaborated through a self-assembly reduction process. FL-Ti3C2Tx not only acts as material but also self-assembles Ni2+ ions electrostatic interaction, assisting in of nano-Ni. After ball milling MgH2, Ni30/FL-Ti3C2Tx (few-layer supported 30 wt % via reduction) shows superior catalytic activity for MgH2. example, MgH2-5 can release approximately...
Abstract Formate production from direct CO 2 electrolysis is economically appealing yet challenging in activity, selectivity, and stability. Herein, sulfur silver dual‐decorated indium quasi‐core–shell structures with compressive or tensile strain are rationally designed for efficiently electrocatalyzing to formate. The introduction of Ag S increases the current density, Faradaic efficiency, operational stability formate both H‐cell flow cell systems. As a result, optimized Ag‐In‐S...
Two-dimensional Ti3C2Tx MXenes exposing different active facets are introduced into MgH2, and their catalytic effects systematically investigated in depth through experimental theoretical approaches. Excluding factors such as interlayer space, surface functional groups contingency, the exposed is considered to be dominant factor for activity of towards MgH2. More edge displays higher than that with more basal facets, which also leads rate-controlling steps MgH2 de/hydrogenation process. The...
Electrochemical CO2 reduction (CO2 R) in acidic media with Cu-based catalysts tends to suffer from lowered selectivity towards multicarbon products. This could principle be mitigated using tandem catalysis, whereby the *CO coverage on Cu is increased by introducing a CO generating catalyst (e.g. Ag) close proximity. Although this has seen significant success neutral/alkaline media, here we report that such strategy becomes impeded electrolyte. was investigated through co-reduction of 13 /12...
Catalysis has been demonstrated to be effective in enhancing the kinetics of MgH2, which widely investigated as one most promising solid-state hydrogen storage materials. It is essential and challenging design catalysts with high activity understand corresponding interaction mechanisms between especially for multiphase catalyst systems. In this study, an elaborated VS2/NiS2 based on well-combined components heterostructure exploited substantially improve performance MgH2. Impressively, rapid...

Catalysts play an extraordinarily important role in accelerating the hydrogen sorption rates metal-hydrogen systems. Herein, we report a surprisingly synergetic enhancement of metal-metal oxide cocatalyst on properties MgH2: only 5 wt % doping Ni into ultrafine TiO2 enables significant increase desorption kinetics; it absorbs 4.50 even at low temperature 50 °C. The striking improvement is partially ascribed to formation particular Ni@TiO2 core-shell structure, thereby forming versatile...
