The hydrogenation of butadiene has been investigated for the first time on Al 13 Fe 4 . The model (010) surface of this non-noble metal combination appears to be both active and selective under mild reaction conditions. The performances of Al 13 Fe 4 for C C bond hydrogenation are compared with those of the reference noble metal, palladium .

Fluorescent silica nanoparticles, which encapsulated dye DCF-BYT with thermally activated delayed fluorescence (TADF) were fabricated by a simple synthetic method. Even in the atmospheric aqueous environment, the obtained DCF-BYT nanoparticles exhibited extremely long TADF lifetime up to 9.33 ms, which imparts these nanoparticles with great potential in biological applications, like time-resolved fluorescence imaging.

A naphthalene substituted histidine derivative was found to form an organogel showing circularly polarized luminescence (CPL) and the addition of non-fluorescent achiral benzoic acids could efficiently enhance the CPL via non-covalent interactions.

Electrochemical N 2 -to-NH 3 fixation under ambient conditions is emerging as a promising alternative to the energy-intensive and CO 2 -emitting Haber–Bosch process. However, this process involves difficulty in N 2 activation, underlining the demand of electrocatalysts for the N 2 reduction reaction (NRR). In this work, cubic sub-micron SnO 2 particles on carbon cloth (SnO 2 /CC) are proposed as an efficient NRR electrocatalyst for ambient N 2 conversion to NH 3 with excellent selectivity. Electrochemical tests reveal that SnO 2 /CC attains a large NH 3 yield of 1.47 × 10 ?10 mol s ?1 cm ?2 at ?0.8 V vs. reversible hydrogen electrode (RHE) and a high Faradaic efficiency of 2.17% at ?0.7 V vs. RHE in 0.1 M Na 2 SO 4 , outperforming most reported aqueous-based NRR electrocatalysts. Notably, it also shows strong electrochemical stability.

An efficient and highly stereoselective synthesis of P -chiral 1,5-diphosphanylferrocene ligands has been developed, and the introduction of P -chirality in ferrocene -based phosphine ligands enhances the enantioselective discrimination produced by the corresponding catalyst when matching of the planar chirality, the chirality at carbon and the chirality at phosphorus occurs.

A simple, efficient and sustainable method for the general synthesis of NHC gold( I ) complexes is described. The reaction of imidazolium salts, of different electronic and steric requirements, with [AuX(tht)] (tht = tetrahydrothiophene) derivatives, in the presence of NBu 4 (acac), in air and at room temperature leads to the NHC gold species in good yields and with very short reaction times.

Supported Fe ions on ion-exchange resin can be used to efficiently photodegrade organic pollutants in water with H 2 O 2 at neutral pHs; this catalyst also significantly depresses the side-reaction of H 2 O 2 conversion to O 2 .

A difunctionalization of alkenes through sequential addition of a radical and a nucleophile has been developed, which is suggested to proceed by a radical chain mechanism not requiring a catalyst. An electron transfer step to the oxidant benzoyl peroxide is facilitated by protonation with a strong acid.

A highly efficient homogeneous catalyst system for production of CH 3 OH from CO 2 using single molecular defined ruthenium and rhodium RAPTA-type catalysts [Ru(η 6 - p -cymene)X 2 (PTA)] (X = I( 1 ), Cl( 2 ); PTA = 1,3,5-triaza-7-phosphaadamantane) and rhodium catalysts [Rh(η 5 -C 5 Me 5 )X 2 (PTA/PTA-BH 3 )] (X = Cl( 3 ), H( 4 ) and PTA-BH 3 , H( 5 )) developed in acidic media under mild conditions. A TON of 4752 is achieved using a [Ru(η 6 - p -cymene)I 2 (PTA)] catalyst which represents the first example of CO 2 hydrogenation to CH 3 OH using single molecular defined Ru and Rh RAPTA-type catalysts.

In the last few years, the amidinium?carboxylate interaction has emerged as a powerful tool for the relatively predictable construction of families of three dimensional hydrogen bonded organic frameworks. These frameworks can be prepared in water and are surprisingly stable, including to heating in polar organic solvents and water. This feature article describes the design and synthesis of these materials, discusses their structures and stability, and highlights their recent applications for enzyme encapsulation and as precursors for the synthesis of molecularly thin hydrogen bonded 2D nanosheets.
