Abstract Etidronic acid (HEDP) and Nitrilotri(methylphosphonic acid) (ATMP) were selected as heteroatoms‐containing ligands to modify Au catalysts for acetylene hydrochlorination. Results from several analytical methods reveal an optimal mole ratio of Au/ligand (L) 1 : 1, with obvious increments over the ‐L /AC catalyst. The coordination between heteroatoms, especially collocative presence N, P, O promoted electron transfer heteroatoms n + increased density cloud around active centers. This...
The Ru-based catalysts, including Ru/AC (activated carbon), TPAP (tetrapropylammonium perruthenate)/AC, TPAP/AC-HNO3, and TPAP/AC-HCl, were prepared assessed for the direct synthesis of vinyl chloride monomer. results indicate that TPAP/AC-HCl catalyst exhibits best performance with conversion falling from 97% to 91% in 48 hours’ reaction under conditions 180 °C, a GHSV(C2H2) h−1, feed ratio VHCl/VC2H2 1.15. substitution RuCl3 precursor high valent species leads more ruthenium oxides active...
Regulation of the Ru/Cl ratio could increase amount ruthenium oxides, improve dispersion Ru species on carrier and enhance adsorption ability reactants, consequently improving catalytic performance.
Abstract In complicated urban environments, Global Navigation Satellite System (GNSS) signals are frequently affected by building reflection or refraction, resulting in Non-Line-of-Sight (NLOS) errors. severe cases, NLOS errors can cause a ranging error of hundreds meters, which has substantial impact on the precision and dependability GNSS positioning. To address this problem, we propose reliable identification method based Light Gradient Boosting Machine (LightGBM), is driven multiple...
A series of catalysts, including Ru/AC, Ф-P-Ru/AC, Ф-P-Ru/AC-HCl, and Ф-P-Ru/AC-HNO3, were prepared evaluated for the hydrochlorination reaction acetylene. The test results reveal that Ф-P-Ru/AC-HNO3 catalyst shows superior catalytic performance with an initial acetylene conversion 97.2% a relative increment 87.0% within 48 h in comparison traditional RuCl3 catalyst. substitution inorganic precursor by organic Ф-P-Ru complex species catalysts more active tends to confine them micro-pores;...
Ru-based catalysts modified in different atmospheres by plasma technology were prepared to catalyze the acetylene hydrochlorination reaction. The (Ru/AC)-N2 (AC = activated carbon) catalyst yielded modification of Ru/AC N2 atmosphere exhibits best catalytic performance with a stable C2H2 conversion 87.2%; relative increase 27.1% was achieved compared that untreated catalyst. results analysis revealed produced mutual effect between generated function groups on carrier AC and active...

Ammonia nitrogen (NH4+-N) is one of the regular indexes and most important contaminants in drinking water. However it still a great challenge to remove low concentration NH4+-N from water safe way. Here we used NaX zeolite alkali-modified (NaX-A) as adsorbents catalysts for ozonation without adding any chemicals. The zeolites present significant adsorption with Freundlich affinity 2.10-3.27 mg1-n·L-n·g-1 by ion-exchange on bridged Si-O-Al groups. NaX-A catalytic achieves 26.7% removal up...

Abstract The conversion of Methyl 3‐hydroxypropionate (3‐HPM) to 1,3‐propanediol (1, 3‐PDO) is an important step in the pathway towards longterm sustainable production ethylene oxide hydroesterification. However, 3‐HPM prone side reactions like hydroxyl β‐dehydration and low reaction efficiency, which hinders its development. This study presents first‐ever report on highly efficient gallium‐promoted Cu/SiO 2 catalysts prepared using ethanol‐assisted ammonia‐evaporation (Et‐AE) for converting...
A 3D honeycomb-like copper-organic framework is fabricated by in situ ligand transformation. The novelty for this its remarkable uptake performance toward iodine vapor and selective sensitivity recognizing the iodate anion.
Ammonia nitrogen, which exists in the dominant form of ammonium ion (NH4+) under pH 6.5 - 8.5, is one regular indexes and most important pollutants drinking water. The selective conversion NH4+ into harmless substances urgently needed also a great challenge. Herein we propose new pathway based on catalytic ozonation process with birnessite-type MnO2 (δ-MnO2) catalysts. δ-MnO2 exhibits superior performance for (1.0 mg/L) removal adsorption (8.26%) oxidation (44.6%) as well up to 95.2% N2...
