Article Synopsis
- Below 28 nm in diameter, the surface structure of anatase titania changes, affecting bond lengths and lattice parameters alongside a shift in point of zero charge (PZC) towards lower pH values.
- The study aimed to correlate the structural changes of titania with the decrease in PZC values as particle size shrinks, using a method that controlled other variables.
- The findings revealed two distinct regions: Region I (above 29 nm diameter) where PZC stays constant, and Region II (below 29 nm) where PZC decreases linearly due to changes in band gap, lattice parameters, and ionic content.
This is the first work to investigate if and/or how changes in the surface structure/properties affect the charge transfer resistance ( ) of anatase titania with decreasing particle size. It was accomplished by measuring the (Ω) of same weight anatase titania pellets, with particle sizes ranging from 5.31 nm to 142.
