Further analysis indicated that the electrocoagulation treatment affected microplastic polymers physically, viz. flaking and changed surface conditions, as well as chemically, viz. changes in vibrational energies of C–O–C stretching bonds, C=O stretching bonds, C–H stretching bonds and formation of reactive oxygen species (ROS). Our findings indicate that whilst seemingly effective, electrocoagulation treatment induces changes to microplastic polymers that could beneficially lead to degradation, and/or further fragmentation or breakdown and thereby potentially generating more bioavailable toxic nanoplastic byproducts.]]> Thu 15 Feb 2024 14:47:55 AEDT ]]> Coupling 0D and 1D carbons for electrochemical hydrogen production promoted by a percolation mechanism https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:38932 -2, a small Tafel slope of 87 mV dec-1 and prominent durability. Percolation theory was for the first time introduced to interpret the catalytic mechanism of the CD/CF catalysts. The special morphology assembled by the 0D carbons constituted the percolating clusters and promoted electron transport throughout the 1D carbons. The strategy and theory can be adapted to general electrocatalytic applications for achieving and interpreting precise tuning on highly efficient electron transfer in electrocatalysts.]]> Fri 15 Sep 2023 15:54:21 AEST ]]>
