Nickel is a promising Pd alternative candidate for selective alkynes/alkadienes hydrogenation owing to its high catalytic activity and cheap price, however, with fatal restrictions of low alkenes selectivity and inferior stability caused by its strong olefin adsorption and the cleavage of carbon-carbon bond. Herein, controlled amounts of iron were introduced into nickel as catalytic assistant by deposition-precipitation with urea on TiO 2 support. Using 1,3-butadiene in an excess of propylene to simulate the industrial process, the additional Fe shows a significant enhancement to the catalytic performance of Ni, i.e., Ni-Fe/TiO 2 with Ni/Fe atomic ratio 1:0.33 shows >94% of 1,3-butadiene conversion and >95% of alkenes selectivity after above 200 h of time on stream, superior to that of commercial Pd/Al 2 O 3 catalyst. Further in-situ analysis reveals that the alloying effect from the formation of Ni-rich Ni-Fe intermetallic compound (e.g., Ni 3 Fe alloy) enlarges the distance between two Ni active sites and enriches the electronic density of Ni sites, resulting in a weak adsorption of butenes products for offering such excellent catalytic performance. To the best of our knowledge, this is the first in-depth exploration on supported Ni-Fe bimetallic catalyst for selective hydrogenation of light alkynes/alkadienes. It shows a high potential for replacing the commercial Pd-based catalysts.

Copper based catalysts have high potential for the substituent of noble-metal based catalysts as their high selectivity and moderate activity for selective hydrogenation reaction; however, achieving further high catalytic stability is very difficult. In this work, the carbonization process of Cu-based organic frameworks was explored for the synthesis of highly-dispersed Cu supported by hierarchically porous carbon with high catalytic performance for selective hydrogenation of 1,3-butadiene. The porous hierarchy of carbon support and the dispersion of copper nanoparticles can be precisely tuned by controlling the carbonization process. The resultant catalyst carbonized at 600 °C exhibits a rather low reaction temperature at 75 °C for 100% butadiene conversion with 100% selectivity to butenes, due to its reasonable porous hierarchy and highly-dispersed copper sites. More importantly, unprecedentedly stability of the corresponding Cu catalyst was firstly observed for selective 1,3-butadiene hydrogenation, with both 100% butadiene conversion and 100% butenes selectivity over 120 h of reaction at 75 °C. This study verifies that a simply control the carbonization process of metal organic frameworks can be an effective way to obtain Cu-based catalysts with superior catalytic performance for selective hydrogenation reaction.

Effect of Constituent Core-sizes on Microstructure and Dielectric Properties of BaTiO_3@(0.6BaTiO_3-0.4BiAlO_3) Core-Shell material

The fundamental characteristics of varied initial core-sizes of Ba Ti O3（BT） and its influential role on the morphology and dielectric properties of Ba Ti O3@0.6 Ba Ti O3-0.4 Bi Al O3（BT@0.6 BT-0.4 BA） ceramic samples were studied. Alkoxide sol-precipitation method was adopted as revised chemical route to synthesize the constituent ＂core＂ BT powders in a dispersed phase, whereas the distinctive initial nano-sized particles were affected by the pre-calcination temperatures（600-900 ℃）.The microstructure of the uncoated BT ceramics revealed an exaggerated grain growth with an optimized dielectric constant（ε（max）〉9 000） whilst the coated ceramics behaved otherwise（grain growth inhibited） when sintered at an elevated temperature. Regardless of the previously studied solubility limit（about 0.1%） of BT-BA samples, BT@0.6 BT-0.4 BA maintained a maximum dielectric constant（ε（max）） ranging from 1 592 to 1 708 and tan δ less than 2% under a unit mole ratio at room temperature. In view of all these analyses, the initial nanometer sizes of the as-prepared BT-core powders combined with the increase effect of cation substitutions of Bi^（3＋） and Al^（3＋） in the shell content, induced the diffuse transition phase of BT@0.6 BT-0.4 BA composition.

The advancement of efficient, cheap, and durable catalysts for oxygen reduction reaction (ORR) to substitute Pt/C in metal-air batteries is of paramount importance. However, traditional solvent-based methods fall short in terms of environmental benign and scalability. Herein, a solvent-free organic-inorganic self-assembly approach is explored to construct cobalt single atom and cobalt nanocluster decorated nitrogen-doped porous carbon spheres (Co-SA/NC@NCS). The solvent-free synthesis demonstrates an impressively high yield (282 g/L) and the resultant Co-SA/NC@NCS possesses a high N content (6.9 wt%). Density functional theory calculations disclose that the Co-SAs and Co-NCs are able to optimize the surface oxygen adsorption capability and enhance the conductivity of the NCS, thereby facilitating the ORR performance. The solvent-free synthesis is also feasible for the synthesis of other non-noble metal element (Fe, Ni, and Zn) decorated nitrogen-doped porous carbon spheres.

Continuous hydrogen-bond-network in aqueous electrolytes can lead to uncontrollable hydrogen transfer, and combining the interfacial parasitic electron consumption cause the side reaction in aqueous zinc metal batteries (AZMBs). Herein, hydrogen/electron amphiphilic bi-functional 1,5-Pentanediol (PD) molecule was introduced to stabilize the electrode/electrolyte interface. Stronger proton affinity of -OH in PD can break bulk-H 2 O hydrogen-bond-network to inhibit the activity of water, and electron affinity can enhance electron acceptation capability, which ensures that PD is preferentially bound to electrode material over H 2 O. Besides, the participation of PD in the Zn 2+ solvation structure reduces water content at the solid–liquid interface and promotes uniform deposition process by optimizing Zn 2+ de-solvation energy. Accordingly, dense and vertical zinc texture based on intrinsic steric hindrance effect of PD and formed SEI protective layer to induce stable Zinc anode-electrolyte interface. Moreover, an organic–inorganic shielding water layer was formed at the cathode side to suppress vanadium dissolution in vanadium Oxide. Consequently, Zn//Zn symmetric cell could cycle for more than 5600 hours at 1 mAh cm −2 @1 mA cm −2 (more than 250 hours at 50 °C). Besides, the VO 2 and I 2 cathode all achieved stable cycling performance and former pouch cell could reach average capacity of 0.13 Ah.

Sustainable processes for semi-hydrogenation of alkynes/alkadienes impurities in alkenes feedstocks are in great demand in industry as the utilization of excessive hydrogen, high temperature and unsatisfactory alkenes selectivity of the current thermo-catalytic route, however, their development is still challenging. Herein, we innovate a light-assisted semi-hydrogenation process in gas-feed fixed bed reactor, with water as hydrogen atom source by in situ photocatalysis. Using Pd/TiO 2 as model catalyst, this process shows an excellent catalytic performance for the semi-hydrogenation of 1,3-butadiene, with 100 % of butenes selectivity at ≈99 % of conversion over 180 h of reaction at ambient temperature driven by 66 mW cm −2 of irradiation intensity. This light-driven, H 2 -free, ambient temperature semi-hydrogenation process, with superior performance to that of thermocatalytic route, shows attractive to bring an evolution in industrial hydrogenation technology to an economical and safe way.
