This paper investigates ammonia decomposition in a coaxial dielectric barrier discharge reactor driven by AC and nanosecond pulse excitations, systematically varying pulse width, rise time, and fall time to reveal impacts on electrical behavior and NH3 conversion. The study introduces energy utilization efficiency (EUE) and shows nanosecond-pulsed DBD outperforming AC-DBD, reaching up to 99.5% NH3 conversion with enhanced transient excitation and limited macroscopic gas heating.","cbCaieuLMaYvuedP","https://ap.wps.com/l/cbCaieuLMaYvuedP","pdf",5850131,1,17,"English","en","# Abstract/Green foundation\n# Introduction\n## Hydrogen and ammonia as an energy pathway\n## Challenges of conventional ammonia decomposition\n## Rationale for non-thermal plasma and DBD","[{\"question\":\"What technology and reactor configuration are used to decompose ammonia in this study?\",\"answer\":\"The study uses a coaxial dielectric barrier discharge reactor driven by alternating current (AC) and nanosecond pulse (NP) excitation to decompose ammonia into hydrogen under atmospheric pressure.\"},{\"question\":\"How do pulse parameters influence ammonia conversion and energy use?\",\"answer\":\"Increasing pulse width prolongs temporal energy deposition and improves effective energy utilization, leading to higher NH3 conversion and better EUE.
