Abstract Benzene is a widely used commodity chemical, which currently produced from fossil resources. Lignin, waste lignocellulosic biomass industry, the most abundant renewable source of benzene ring in nature. Efficient production lignin, requires total transformation C sp2 -C sp3 /C -O into C-H bonds without side hydrogenation, great importance, but has not been realized. Here, we report that high-silica HY zeolite supported RuW alloy catalyst enables situ refining exclusively to via...
Abstract Using renewable electricity to drive CO 2 electroreduction is an attractive way achieve carbon‐neutral energy cycle and produce value‐added chemicals fuels. As important platform molecule clean fuel, methanol requires 6‐electron transfer in the process of reduction. Currently, suffers from poor efficiency low selectivity. Herein, we report first work design atomically dispersed Sn site anchored on defective CuO catalysts for methanol. It exhibits high Faradaic (FE) 88.6 % with a...
Non-copper electrocatalysts are seldom reported to generate C2+ products, and the efficiency over these catalysts is low. In this work, we report a nitrogen-doped γ-Fe2O3 (xFe2O3-N@CN) electrocatalyst, which yield C2H6 as major product in an H-cell. At −2.0 V vs Ag/Ag+, Faradaic (FE) for ethane reaches 42% with current density of 32 mA cm–2. This first about selective CO2 reduction (C2H6) iron-based catalyst. The results showed that catalyst possessing FeO1.5–nNn sites enriched oxygen...
Electrochemical reduction reaction of carbon monoxide (CORR) offers a promising way to manufacture acetic acid directly from gaseous CO and water at mild condition. Herein, we discovered that the graphitic nitride (g-C3 N4 ) supported Cu nanoparticles (Cu-CN) with appropriate size showed high acetate faradaic efficiency 62.8 % partial current density 188 mA cm-2 in CORR. In situ experimental functional theory calculation studies revealed Cu/C3 interface metallic surface synergistically...
Cyclohexanone and benzoquinone are important chemicals in chemical manufacturing industries. The simultaneous production of cyclohexanone by the reaction phenol water is an ideal route for economical two chemicals. In principle, this can be achieved electrochemical system that couples cathodic reduction to anodic oxidation benzoquinone, which has not been realized. Here, we report first work on integration strategy, where nitrogen-doped hierarchically porous carbon (NHPC)-supported NiPt FeRu...
The electroreduction of CO
Prototype lanthanide metal-organic frameworks (LnMOFs), Ln(BTC) (Ln = Eu and Tb; BTC benzene-1,3,5-tricarboxylate), have been considered as luminescent sensors for detecting toxic anions, while their neutral pore structures limited the entrance encapsulation of anions to produce highly anion-responsive photoluminescence (PL). To facilitate enter space Ln(BTC), a one-pot synthesis method was proposed in which partially replaced with its structural analogue L·BF4 (H3L·BF4...
<title>Abstract</title> Biomass-derived recyclable materials that can replace petrochemical-derived plastics are highly sought for a sustainable future. However, incumbent often face performance deterioration challenges owing to the aging issues after use in environment. We present self-reinforcing, recyclable, unprecedented polyester material derived entirely from biomass lignin and soybeans, mimicking self-reinforcement mechanism of biological systems. Our leverages [2+2]-cycloaddition...

It found there obviously exist a...
Location prediction has attracted increasing attention in diverse fields due to its wide applications, such as traffic planning and control, weather forecasting, homeland security, travel recommendation. Many existing algorithms forecast a user's next location by learning that past moving patterns. However, the individual patterns many practical applications (e.g., trajectory of taxi driver) tend be random, which poses big challenge for prediction. In this paper, we propose new robust model...
