چکیده
Electrochemical CO2 reduction (ECR) powered by renewable electricity is reckoned to provide an effective strategy alleviate environmental issues and energy crisis, enabling a potential carbon neutral economy. To boost the ECR fuels value-added chemicals, design of highly active selective catalysts important. In this study, we demonstrate facile ultrasonication-facilitated synthesis two-dimensional copper terephthalate for efficient ECR. High faradaic efficiencies (FEs) up 72.9% hydrocarbons are achieved at mild overpotential in H-type cell. particular, FE ethylene (C2H4) formation approaches 50.0% applied −1.1 V (vs. reversible hydrogen electrode), outperforming commercial Cu, Cu2O, CuO, Cu(OH)2 many recently reported Cu-based materials. The C2H4 partial geometric current density as high ∼6.0 mA·cm−2. This work offers simple avenue developing advanced electrocatalysts converting into high-value hydrocarbons.

A facile and efficient synthesis of Baclofen
γ-Aminobutiric acid (GABA), the major inhibitory neurotransmitter in the central nervous system is activated by the antispastic and muscle relaxant agent, Baclofen, which is a lipophilic derivative of GABA. Because of its biological and pharmacological importance, there are several reports in the literature about the synthesis of baclofen since 1962. In this study baclofen was easily synthesize...
