Moreover, we demonstrate the efficient utilization of p(AAm)-CB composite hydrogel as a reactor vessel in the reduction of an organic contaminant 4-nitrophenol (4-NP) to 4-aminophenol (4-AP). Experimental parameters affecting 4-NP reduction rate were investigated. The kinetics of the reduction reaction under different reaction conditions were also evaluated to determine the activation parameters. Activation energy for the reduction of 4-NP was 15.25kJmol1 and p(AAm)-CB-Ag composites possessed 99.45% activity after five repetitive uses.eninfo:eu-repo/semantics/closedAccessFlexible NanonetworkHydrogel ReactorHydrogel-Biochar CompositeIn Situ Metal Nanocatalyst Preparation4-Nitrophenol ReductionArticle6211N/AQ1590595WOS:000316929600004
