In the present work, we report on a comparative study of model catalysts in the ethylene epoxidation reaction consisting of Ag nanoparticles < 6 nm and a reference sample ~ 100 nm operated under industrially relevant conditions. Combining catalytic data with transmission electron microscopy, thermal desorption spectroscopy, and density functional theory allows us to show that catalytic performance

The propoxylation of fatty amines is a crucial reaction in the industrial production of surfactants. Catalyzing this reaction has so far proven unrewarding due to severe selectivity losses. In this study, rigid foam‐structured polyurethane, i.e., a material which has not been used as a catalyst ever before, shows an unprecedented catalytic activity during the in‐flow propoxylation of octylamine. The

We report a carbazolyl porphyrin‐based π‐conjugated microporous polymer via simple FeCl 3 ‐catalyzed oxidative polymerization. The resulting polymer (TCPP‐CMP) exhibits high surface area, permanent pores, outstanding stability, broad light absorption range as well as suitable redox potentials. As expect, TCPP‐CMP is shown to be a highly effective metal‐free and heterogeneous photocatalyst for a variety

First-principles method based on density functional theory is applied to calculate the Mg(0001)/TiN(111) interfacial properties, including adhesion work, electronic structure and interface energy. The Mg(0001) slab with five atomic layers and TiN(111) slab with thirteen layers were used to construct the interfaces after the surface convergence test. And three Mg(0001)/TiN(111) interfaces with different

Cobalt‐catalyzed reductive carboxylation of aryl bromides with carbon dioxide has been developed. The reaction proceeded under one atm pressure of CO2 at 40 °C in the presence of cobalt iodide/2,2'‐bipyridine catalysts and zinc dust as a reducing reagent. Various aryl bromides could be converted to the corresponding carboxylic acids in good to high yields. Preliminary mechanistic experiments ruled

The rising demand for enhanced catalytic pathways for activation of small molecules has invoked the design and synthesis of metal-free heterogeneous catalysts. Despite the great potential of these catalysts, very few precedents have been accounted. Thus, we have prepared two boron doped carbon nitride with neighboring surface active Lewis acidic (B) and Lewis basic (N) sites, and undoped carbon nitride

Enantioselective allylation of aldehydes and ketones is a widely used approach for preparing chiral homoallylic alcohols, however, most of the reactions are still mainly performed in organic solvents. Considering their environmental impact, expansion of synthetic technology in water has the highest priority in the organic chemistry field. Here, we report enantioselective reaction of water‐stable amido‐functionalized

The ligand effect on chemo-/regio-selectivity and reactivity of cobalt-catalysed hydroformylation has been discussed. The results of unmodified cobalt carbonyl catalyst show that the regioselectivity of terminal alkene substrate is mainly affected by the bulky steric hinderance of alkyl substitution group and insensitive to the elongation of carbon chain. Regarding the Co-H addition onto alkene, modifying

In this work, we reported an efficient and universal method to fabricate perovskite quantum dot (PQD) solar cells with enhanced efficiency. Through dissolving optimal amount conjugated polymers in PQD matrix solution to fabricate a polymer-QD bulk heterojunction hybrid layer located at PQD/hole transporting layer (HTL) interfaces, the resultant solar cell devices exhibit significantly enhanced short-circuit

Superwetting materials have been proved as a satisfactory approach to treat simple oil/water emulsions in recent years. However, up to now, they are still incapable of handling double emulsions with a multilayer structure. Here, we modified carbon nanotube (CNT) and Poly(N-isopropylacrylamide) (PNIPAAm) on a Poly(vinylidene fluoride) membrane, realizing photothermal induced in-situ separation of double

Efficient n-doping is a big challenge to organic thermoelectrics due to the requirements of both low ionization potential and good air-stability. In recent years, N-DMBI-H has been reported as a most successful solution-processed n-type dopant precursor, but the doping mechanisms are unclear to date. Here, we have investigated both hydrogen removal and hydride transfer reactions of N-DMBI-H doped in

The band-energy structure, electron mobility and electronic trap states of electron-transporting layer (ETL) are critical for perovskite solar cells (PSCs). However, the state-of-the-art titanium oxide (TiO2) ETL prepared by means of high-temperature processing technology requires a long preparation time and more energy consumption; and the low-temperature processed species always present unfavourable

Aqueous rechargeable zinc-ion batteries (ARZIBs) have recently become a hot spot due to the low cost and high safety. Current research is mainly focused on developing advanced cathode materials, while many studies have demonstrated satisfactory electrochemical performances with high capacity and rate capability. However, two prevalent problems are widely encountered: the byproduct formation and poor

The progress of two-dimensional (2D) MXenes-derived QDs (MQDs) is at its nascent stage, but they have aroused great interest due to the high chemical stability, satisfactory dispersibility, remarkable optical properties, good biocompatibility, and manifold functionalization, and so on. However, up to now, there is still lack of review paper on MQDs. Herein, the research advance of MQDs, including their

The PM6:Y6 bulk‐heterojunction (BHJ) blend system achieves high short‐circuit current (JSC) values in thick photovoltaic junctions. Here we analyse these solar cells to understand the observed independence of the short-circuit current upon photoactive layer thickness. We employ a range of optoelectronic measurements and analyses, including Mott-Schottky analysis, CELIV, photoinduced absorption spectroscopy

The wide applications of lithium metal batteries (LMBs) are greatly limited by the notorious side reactions and dendrite growth due to the highly reactive nature of lithium metal paring with the traditional liquid electrolytes. Herein, we report a synergetic strategy by combining an ex-situ chemical pretreatment on lithium metal anode (LMA) and an in-situ cationic polymerization of DOL to tackle those
