Green dodecylamine-capped hafnium oxide nanosystem: evaluating the toxicity profile and electrochemical hydrogen sulfide sensing efficiency
This research, for the first time, reports the fabrication of dodecylamine-capped hafnium oxide nanomaterial (DDA@HfO 2 NM) onto gold (Au) electrodes for the highly selective and sensitive detection of sulfide (HS − ) electrochemically. A facile, green, and economic two-step hydrothermal optimized a...
