Selective and Generic Photocatalytic Oxidation of Alcohol with Pd‐TiO2 Thin Films: Butanols to Butanal/Butanone with Different Morphologies of Pd and 0.5θPt‐Pd Counterparts

Present study reports on photocatalytic oxidation of butanols to butanal/butanone using thin film form of facet-dependent nano-Pd supported on commercial TiO2 under one sun condition and demonstrates the generic nature. Pd-nanocube (PdNC(100)), Pd-truncated octahedron (PdTO (100) and (111)), polycrystalline (PdPC), and their counterparts with half-a-monolayer...

Boat and Chair Shaped Hexahalogen Synthons

Non-covalent halogen bonding interactions are quintessential in crystal engineering for the construction of distinctive supramolecular synthons. Here, we report the first crystalline evidences of unique boat and chair shaped cyclic hexahalogen synthons in the crystal structures of α,α,α',α',4-pentabromo-o-xylene (PBX) and α,α,α',α',4,5-hexabromo-o-xylene...

Recent Advances of Core‐Shell Cu‐Based Catalysts for the Reduction of CO2 to C2+ Products

Combining the advantages of core-shell structure and copper paves an effective way to largely improve the FE of multi-carbon products in CO2RR. In this review, the research progress of Cu-based core-shell catalysts on multi-carbon products was summarized, which provids new insights for the design of CO2RR catalysts in the future. Abstract Copper...

Mesomeric Betaines Based on Adamantylated 1,2,4‐Triazolo[4,3‐a]pyrimidin‐5‐ones: Synthesis, Structure and Conversion into Anionic N‐Heterocyclic Carbenes

The C−N coupling of 1,2,4-triazolo[1,5-a]pyrimidin-7-ones with 1-adamantanol/1-bromoadamantane leads to 1,2,4-triazolo[4,3-a]pyrimidinium-5-olates, which are considered as mesomeric betaines (MBs). Deprotonation of these MBs with lithium bis(trimethylsilyl)amide led to new types of anionic N-heterocyclic carbenes (aNHCs), which were characterized by...

Recent Advances for Electrode Modifications in Flow Batteries: Properties, Mechanisms, and Outlooks

As the electrochemical reaction site, the electrode parameters, such as the specific surface area, active site, and so on, have a significant impact on the flow battery performance and reliability. In this review, the reaction mechanisms of VFBs and ICFBs are discussed in detail firstly, and then the electrode modification methods are overviewed and...

Substituted Isocoumarins: An Assemble of Synthetic Strategies Towards 3‐Substituted and 3,4‐Disubstituted Isocoumarins

A review update covering all the articles that have been published towards the synthesis of 3-substituted and 3,4-disubstituted isocoumarins has been complied. Additionally, we have also highlighted a systematic survey of catalytic methods for their synthesis along with their scope towards diverse functionalization and plausible mechanistic aspects....

Systematic Study of Podand Molecules for Synergistic Halogen and Hydrogen Bond Driven Anion Recognition in the Solid State

The increasing demand of species for the efficient capture and sensing of anions benefits from a systematic study of anion binding capabilities in the solid state. This work reports a detailed crystallographic study of ten structurally related podands and shows that these charged receptors bind anions with a combination of charge-assisted halogen and...

Photoinduced Synthesis of Bisphosphinated Quinoxalines via Radical Cyclization of o‐Diisocyanoarenes with Diphosphines

The cycloaddition reaction of o-diisocyanoarenes with interelement compounds under light is a very important reaction system to clarify whether this reaction proceeds by radical cyclization or by aza-Bergman cyclization. In this study, a series of diphosphines with phosphorus-phosphorus single bonds were selected as interelement compounds, and their...

Combustion‐assisted polyol reduction method to prepare highly transparent and efficient Pt counter electrodes for bifacial dye‐sensitized solar cells

Combustion-assisted polyol reduction (CPR) method is developed to deposit electrocatalytically efficient and transparent Pt counter electrodes (CEs) for bifacial dye-sensitized solar cells (DSSCs). Compared with conventional thermal decomposition of Pt precursors, CPR allows for a decrease in reduction temperature to 150°C. The low-temperature processing...

The “nitrogen effect”: Complexation with macrocycles potentiates fused heterocycles to form halogen bonds in competitive solvents

Weak intermolecular forces are typically very difficult to observe in highly competitive polar protic solvents as they are overwhelmed by the quantity of competing solvent. This is even more challenging for three-component ternary assemblies of pure organic compounds. In this work, we overcome these complications by leveraging the binding of fused aromatic...
