Anthropogenic activities have disrupted the natural nitrogen cycle, increasing level of contaminants in water. Nitrogen are harmful to humans and environment. This motivates research on advanced decarbonized treatment technologies that capable removing or valorizing waste found In this context, electrocatalytic conversion inorganic- organic-based compounds has emerged as an important approach is upconverting into valuable compounds. differs from state-of-the-art wastewater treatment, which primarily converts inorganic dinitrogen, organic sent landfills. Here, we review recent efforts related waste. Specifically, detail role electrocatalyst design (alloys, defects, morphology, faceting) plays promotion high-activity high-selectivity electrocatalysts. We also discuss impact constituents. Finally, critical product analyses required ensure reported performance accurate.

The synthesis of ammonia starting from nitrogen and using electrochemical processes is considered an interesting strategy to produce in a sustainable way. However, it requires not only the development efficient catalysts for reduction but also optimization operating conditions employed devices. In this work, we optimize kinetics thermodynamics electrocatalytic reaction water by developing pressurized H-cell that may operate at temperatures up 80 °C. Ni foam with low Au loading (0.08 mg cm−2) has been adopted as catalyst cathode. Ammonia produced during chronoamperometry experiments saturated N2 atmosphere measured indophenol blue method. effect voltage, temperature, pressure studied. have repeated under Ar. To remove contributions due environmental contamination, determined net value difference between yield increases increasing temperature pressure. best results obtained combined effects Operating 5 bar 75 °C, production rate 6.73 μg h−1·cm−2 obtained, corresponding 5-fold enhancement, compared ambient room temperature.
