ZENG Wei, PENG Yongzhen, WANG Shuying

Frontiers of Environmental Science & Engineering 2007, Volume 1, Issue 1,   Pages 28-32 doi: 10.1007/s11783-007-0005-5

Abstract: Under sufficient influent alkalinity, the AAA process did not have an advantage over one aerobicanoxicUnder deficient influent alkalinity, when compared to OAA, the AAA process improved treatment efficiencyThat was why the higher treatment efficiency in the AAA process was achieved without the supplement of bicarbonatealkalinity.alkalinity addition and treatment efficiency was the same as that under sufficient influent alkalinity

Boosting the direct conversion of NHHCO electrolyte to syngas on Ag/Zn zeolitic imidazolate framework derived nitrogen-carbon skeleton

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 9,   Pages 1196-1207 doi: 10.1007/s11705-022-2289-1

Abstract: The electrochemical reduction of NH4HCO3 to syngas can bypass the high energy consumption of high-purity CO2 release and compression after the ammonia-based CO2 capture process. This technology has broad prospects in industrial applications and carbon neutrality. A zeolitic imidazolate framework-8 precursor was introduced with different Ag contents via colloid chemical synthesis. This material was carbonized at 1000 °C to obtain AgZn zeolitic imidazolate framework derived nitrogen carbon catalysts, which were used for the first time for boosting the direct conversion of NH4HCO3 electrolyte to syngas. The AgZn zeolitic imidazolate framework derived nitrogen carbon catalyst with a Ag/Zn ratio of 0.5:1 achieved the highest CO Faradaic efficiency of 52.0% with a current density of 1.15 mA·cm–2 at –0.5 V, a H2/CO ratio of 1–2 (–0.5 to –0.7 V), and a stable catalytic activity of more than 6 h. Its activity is comparable to that of the CO2-saturated NH4HCO3 electrolyte. The highly discrete Ag-Nx and Zn-Nx nodes may have combined catalytic effects in the catalysts synthesized by appropriate Ag doping and sufficient carbonization. These nodes could increase active sites of catalysts, which is conducive to the transport and adsorption of reactant CO2 and the stability of *COOH intermediate, thus can improve the selectivity and catalytic activity of CO.
