Electrocatalytic CO2 reduction to C2 products is a promising technique when compared with the traditionally complicated and energy intensive routes in the industrial process. As an important bulk chemical, it is highly desirable for acetic acid to be produced via a sustainable method. In this work, we prepared N-based Cu(I)/C-doped boron nitride (BN-C) composites for electrocatalytic reduction of CO2 to acetic acid. It was found that the Faradaic efficiency of acetic acid could reach as high as 80.3% with a current density of 13.9 mA cm-2 when 1-ethyl-3-methylimidazolium tetrafluoroborate ([Emim]BF4)-LiI-water solution was used as the electrolyte, which was about 4 times higher than the best value reported in the literature. Detailed studies further indicated that the Cu complex, BN-C, and the electrolyte have an excellent synergistic effect for producing acetic acid. In particular, as a promoter, LiI played a key role in C-C coupling to form acetic acid in the electrocatalytic process. Our study shows a promising way to produce C2 products via electrochemical reduction of CO2 by the combination of composite electrodes and electrolytes with a promoter.

Two low-dimensional molybdenum(VI) oxide/organic hybrid materials crystallize hydrothermally from acidic reaction mixtures containing 2,2?-dipyridylamine. The hydrothermal reactions of MoO3, 2,2?-dipyridylamine and H2O in the molar ratio of 1:0.5:600 at 160C for 96 h afford a one-dimensional solid (C10H10N3)2[Mo6O 19] (1) at pH ? 2 and a two-dimensional solid (C10H10N3)2-[Mo8O 25] (2) at pH < 1. The structure of 1 consists of puckered [Mo12O38]4- chains of corner- and edge-sharing {MoO6} octahedra and {MoO5} square pyramids, and interstrand 2,2?-dipyridylammonium ions. The crystal structure of 2 is constructed from [Mo8O25]2- layers separated by interlamellar 2,2?-dipyridylammonium ions. The successful assembly of low-dimensional network structures of 1 and 2 demonstrates the dramatic influence of reaction acidity on the organization of molecular building blocks and construction of solid architectures. The crystal structures of 1 and 2 are stabilized by electrostatic forces and hydrogen bonds between counterions, and pi-pi interactions among 2,2?-dipyridylammonium ions.

Maltose phosphorylases (EC 2.4.1.8) catalyze the reversible conversion of maltose to glucose and glucose-1-phosphate in the presence of inorganic phosphate. Herein, we describe for the first time the use of a maltose phosphorylase for the synthesis of various anomerically modified diglycosides. The maltose phosphorylase used was isolated from the bacterium Emticicia oligotrophica and showed a high selectivity towards the phosphorolysis of maltose, whereas no phosphorolysis was observed using other glucose-containing disaccharides such as cellobiose, melibiose, sucrose and trehalose. The addition of glucose to various 5-bromo-4-chloro-3-indolyl-glycosides (X-sugars) was used to evaluate the promiscuity of the maltose phosphorylase, and product formation was verified by LC-ESI-MS and MALDI-TOF-MS. The simple expression and purification protocol and the use of maltose as an inexpensive starting material make this maltose phosphorylase from Emticicia oligotrophica a valuable novel biocatalyst for the synthesis of glucose-containing glycosides.

This work demonstrates the utilization of phosphotungstic acid (PTA) as a novel acidic catalyst for carbohydrate reactions, such as per-O-acetylation, regioselective O-4,6 benzylidene acetal formation, regioselective O-4 ring-opening, and glycosylation. These reactions are basic and salient during the synthesis of carbohydrate-based bioactive oligomers. Phosphotungstic acid’s high acidity and eco-friendly character make it a tempting alternative to corrosive homogeneous acids. The various homogenous acid catalysts were replaced by the phosphotungstic acid solely for different carbohydrate reactions. It can be widely used as a catalyst for organic reactions as it is thermally stable and easy to handle. In our work, the reactions are operated smoothly under ambient conditions; the temperature varies from 0 C to room temperature. Good to excellent yields were obtained in all four kinds of reactions.
