Data from: Cu+ transient species mediate Cu catalyst reconstruction during CO2 electroreduction
<p>Understanding metal surface reconstruction is of the uttermost importance in heterogeneous<br> catalysis as this phenomenon directly affects the nature of available active sites. However,<br> surface reconstruction is notoriously difficult to study because of the dynamic nature of the<br> phenomena behind it, particularly when solid/liquid interfaces are involved. Here, we report<br> on the intermediates which drive the rearrangement of copper catalysts for the electrochemical<br> CO2 reduction reaction (CO2RR). Online mass spectrometry and UV-Vis absorption<br> spectroscopy data are consistent with a dissolution–redeposition process, previously<br> demonstrated by in-situ electron microscopy. The data indicate that the soluble transient<br> species contain copper in +1 oxidation state. Density functional theory identifies copper adsorbate<br> complexes which can exist in solution under operating conditions. Copper carbonyls and oxalates are suggested as the major reaction-specific species driving copper reconstruction during CO2RR. This work motivates future methodological studies to enable the direct detection of these compounds and strategies which specifically target them to improve the catalyst operational stability.</p>

Nitrogen‐Doped Carbons with Hierarchical Porosity via Chemical Blowing Towards Long‐Lived Metal‐Free Catalysts for Acetylene Hydrochlorination
<p>Porous nitrogen-doped carbons (NCs) are sustainable alternatives to the toxic mercury-based acetylene hydrochlorination catalysts applied in the manufacture of polyvinyl chloride. However, the application of NCs as metal-free catalysts is hampered by their insufficient durability under industrially relevant process conditions. In particular, pore blockage leads to accelerated deactivation of NCs compared to the state-of-the-art precious metal-based systems. Herein, we develop a salt template-assisted synthesis strategy coupled with chemical blowing to tune the textural properties of NCs, while preserving the N-content and speciation. The addition of metal salts (i.e., Mg(OAc)2 or CaCO3) enhances gas evolution, leading to an increased formation of micro- and mesopores, while the in-situ generated CaO/CaCl2 and MgO/MgCl2 develop auxiliary pore networks. Micropores are easily blocked during acetylene hydrochlorination, but meso- and macropores are structurally stable, enhancing the lifetime of hierarchical NCs by ca. 50 times compared to their non-templated analogues, rivalling the stability of benchmark metal-based catalysts.</p>

Quinoline conjugated imidazopyridine and pyridopyrimidine synthesis in water as highly selective fluoride sensors via a catalyst-free four-component reaction
<p>Abstract</p> <p>A green and convenient procedure for the synthesis of quinoline-conjugated imidazopyridines and pyridopyrimidines has been developed by a simple one-pot reaction in the absence of any transition metal catalyst in water. This green process can be readily performed by reacting inexpensive starting materials of 2-chloroquinoline-3-carbaldehyde, malononitrile, 1,1-bis(methylthio)-2-nitroethylene, and diamine in aqueous solution. The present synthesis shows attractive characteristics, such as the use of water as reaction media, convenient one-pot operation, and reduced waste production without the use of any base or metal promoters. The products are purified by crystallization from ethanol, and the process does not involve any hazardous solvent. Also, the fluorescence study of these conjugated systems was also considered, which revealed that they have highly selective sensing of fluoride.</p>

<p>The hexagonal mesoporous organic–inorganic hybrid as a new nanocatalyst was prepared by the treatment of SBA-15 with (3-chloropropyl)triethoxysilane, the 2,4,6-triamino pyrimidine ligand, and then PdCl2 to obtain the SBA-15-propyl-triamino pyrimidine@Pd called as SBA-Pr-3AP@Pd, which was examined through Suzuki–Miyaura cross-coupling reaction by several aryl halides and phenylboronic acid under mild conditions in high yield.</p>
Data from: Plasma assisted CO2 methanation: effects on the low-temperature activity of a Ni-Ce catalyst and reaction performance
Ni-Ce three-dimensional material with macropore diameter of 146.6±8.4 nm were synthesized and used for methanation catalyst. Firstly, H2-reduction of catalyst was conducted in thermal fixed bed and plasma reactor respectively, then X-ray diffraction (XRD) and CO2 Temperature Programmed Desorption (TPD) experiments on the two reduced samples were carried out to reveal the plasma effect on catalyst's physicochemical properties. It was found that plasma reduction created more abundant basic sites for CO2 adsorption, especially the medium basic sites were even doubled compared with the thermal reduced catalysts. The plasma reduced catalyst exhibited excellent low-temperature activity, ca. 50~60 oC lower than the thermal catalyst (the maximum CO2 conversion point). Based on the optimum reduced catalyst, plasma effect in the reactor level was further investigated under high gas hour space velocity (GHSV) ~50000 h-1. The plasma reactor showed higher CO2 conversion capacity and efficiency than the thermal reactor.
Data from: Irradiation-catalyzed degradation of methyl orange using BaF2-TiO2 nanocomposite catalysts prepared by a sol–gel method
BaF2-TiO2 nanocomposite material (hereinafter called the composite) was prepared by a sol–gel method. And the composite surface area, morphology and structure were characterized by Brunauer-Emmett-Teller (BET) method, X-ray diffraction(XRD) and scanning electron microscopy (SEM). The results showed that BaF2 and TiO2 form a PN-like structure on the surface of the composite. Composites were used to catalyze the degradation of methyl orange by irradiation with ultraviolet light, γ-rays, and an electron beam(EB). It was demonstrated that the composite is found to be more efficient than prepared TiO2 and commercial P25 in the degradation of methyl orange under γ-irradiation. And increasing the composite catalyst concentration within a certain range can effectively improve the decolorization rate of the methyl orange solution. However, when the composite material is used to catalyze the degradation of organic matter in the presence of ultraviolet light or 10 MeV electron beam irradiation, the catalytic effect is poor or substantially ineffective. In addition, a hybrid mechanism is proposed; BaF2 absorbs γ-rays to generate radioluminescence(RL) and further excites TiO2 to generate photo-charges. And due to the heterojunction effect, the resulting photo-charge will produce more active particles. This seems to be a possible mechanism to explain γ-irradiation catalytic behavior.
