Formaldehyde (HCHO), as one of the main indoor toxic pollutions, presents a great threat to human health. Hence, it is imperative efficiently remove HCHO and create good living environment for people. Herein, layered perovskite material SrBi2Ta2O9 (SBT), was studied first time exhibited superior photocatalytic efficiency stability compared commercial TiO2 (P25). Furthermore, unique dark–light t...

We investigate the influence of tetrafunctional alkoxysilan R-groups, with a range sterics and electronics. This is through solvent free polysiloxane network formation under ambient conditions using Lewis acid catalysed Piers-Rubinsztajn (PR) reaction.

Boronic acids can interact with Lewis bases to generate boronate anions, and they can also bind with diol units to form cyclic boronate esters. Boronic acid based receptor designs originated when Lorand and Edwards used the pH drop observed upon the addition of saccharides to boronic acids to determine their association constants. The inherent acidity of the boronic acid is enhanced when 1,2-, ...

TMU-10 treated at 300 °C under air efficiently promotes H 2 generation ambient temperature from NaBH 4 . The enhanced catalytic activity derives a higher density of Lewis acid sites and the mesoporosity.

Lewis acidic zeolites are used to synthesize unsaturated dicarboxylic acid esters via aldol condensation of keto esters. Hafnium-containing BEA (Hf-BEA) zeolites catalyze the condensation of ethyl pyruvate into diethyl 2methyl-4-oxopent-2-enedioate and diethyl 2-methylene-4oxopentanedioate (an itaconic acid ester analogue) with a selectivity of ca. 80% at ca. 60% conversion in a packed-bed reac...

Abstract The palladium-catalysed Suzuki–Miyaura cross-coupling reaction of organohalides and organoborons is a reliable method for carbon–carbon bond formation. This involves base-mediated transmetalation process, but the presence base also promotes competitive protodeborylation. Herein, we established via Lewis acid-mediated an organopalladium(II) intermediate with organoborons. Experimental t...

Dimerisation of alpha-olefins by a catalyst system comprising of a bis(imido) tungsten compound and a Lewis acid component has been investigated by density functional theory employing a catalyst model that closely mimics the real system together with ethylene chosen as a prototypical substrate. This study disclosed that the Lewis acid preferably forms four-membered chelates by bridging across t...
