摘要: Abstract We apply atmospheric pressure plasma jets (APPJs) for the rapid sintering of nanoporous SnO 2 . The influence APPJ duration on properties is investigated. With an increase in time, slope optical absorption edge decreases and then increases, bandgap electrical conductivity increases decreases, activation energy increases. A proper APPJ-sintering time recommended optimal performance sintered prolonged may deteriorate material performance. This sequential screen-printing process scalable can potentially be used a roll-to-roll process, which extensively second follow-up layers owing to alignment requirements. with high surface-to-volume ratio potential candidate gas sensors or catalysts, large surface reactive sites are demanded.
