Preparation and Characterization of Electrocatalysts for CO2 Reduction: A Comprehensive Study

///'In order to prepare the required electrocatalyst for the experiment, ammonium tetrathiomolybdate (//u226599.95%) provided by Shanghai Macklin Biochemical Technology Co., Ltd. and silver nitrate (AR) provided by Guangdong Wengjiang Chemical Reagent Co., Ltd. were used. Ethanolamine (AR) purchased from Tianjin Kemiou Chemical Reagent Co., Ltd. was used for washing the electrocatalyst. During the electrocatalyst loading process, anhydrous ethanol (AR) supplied by Tianjin Damao Chemical Reagent Factory was used, along with some deionized water for dissolving the catalyst. Nafion solution (5 wt.%, AR) provided by DuPont and carbon nanotubes (//u226595%) from Zhengzhou Alfa Chemical Co., Ltd. were used for immobilizing the catalyst. Sulfuric acid (AR) from Tianjin Damao Chemical Reagent Factory, 1-butyl-3-methylimidazolium tetrafluoroborate ([Bmim]BF4) (//u226598%) and tetrabutylammonium tetrafluoroborate (TBABF4) (//u226598%) supplied by Shanghai Macklin Biochemical Technology Co., Ltd. were used to construct the H-type electrolytic cell. Carbon dioxide (CO2) and helium gas (He) (both //u226599.99%) were purchased from Baoding Jinglian Gas Plant.///
