Plasmonic energy transformation in the photocatalytic oxidation of ammonium

Review of Experimental Setups for Plasmonic Photocatalytic Reactions

“…Localized heating can be used in photocatalytic reactions [58,222,223]. Using a temperaturedependent photocatalytic measurement approach to acquire the activation enthalpy, Kim et al [87] reported that reduction in activation enthalpy was directly related to the photoelectrochemical potential accumulation on the Au nanoparticle under steady-state light excitation, another phenomenon analogous to electrochemical activation.…”

“…Ammonium oxidization in an SDR mainly increases the mass transfer rate and collision rate of target reactants, which results in reactions under ambient conditions [58]. Providing an additional chemical-stabilized Pt thin film (8 nm) [226] could result in energy compensation in plasmonic endothermic reactions when compared with typical endothermic ammonium oxidization [223].…”

“…SDRs could enhance mass transfer and result in ammonium oxidization at room temperature [58] through the use of a bare-glass disk that typically executed using wet air oxidization method in environment of high temperature and high pressure [224,225]. Depositing an additional 8-nm platinum thin film using plasma-enhanced atomic layer deposition (PE-ALD) [226] has been report to further introduced plasmonic-enhanced photocatalytic ammonium oxidization in water [58,223]. The energy compensated in the plasmonic photocatalytic oxidization of ammonium is a quantized phenomenon independent of the incident light power density [94,230].…”

Effects of external light in the magnetic field-modulated photocatalytic reactions in a microfluidic chip reactor

“…The induced plasmon energy on a metal nanoparticle can be delivered elastically or inelastically by transferring light energy to nearby materials. 3 Optical scattering and trapping by metal nanoparticles to the nearby photocatalysts can increase the photon flux flow through photocatalytic nanoparticles, 4–10 thus enhancing the photocatalytic reaction through the plasmon elastic decay path. On the other hand, numerous inelastic decay paths, e.g.…”

Magnetic Field-Enhancing Photocatalytic Reaction in Micro Optofluidic Chip Reactor

“…Many methods have been suggested for improving the performance of photocatalytic reactions, such as through material modification and introducing new types of photocatalytic reactors [1–4]. Material modification or using composite materials [5–10] and plasma treatment [11–13] have also been suggested to improve photocatalytic processing efficiency.…”
