X-ray diffraction (XRD)
measurements were
performed with a Bruker D8 Advance diffractometer. X-ray fluorescence
(XRF) experiments were carried out with an S8TLGER (Bruker). The morphologies
of the modified electrode surfaces were observed using field emission
scanning electron microscopy (FE-SEM, ΣIGMA-HD, ZEISS, Germany).
Raman spectroscopy was performed using a laser micro-Raman spectrometer
(JASCO NRS-4100, Japan) with an excitation wavelength of 532.0 nm
laser with a working distance on a ×100 lens. The Raman spectra
of MLN, MLN/TYR, and MLN/AO/TYR were recorded by depositing the samples
on a GCE rod (3 mm in diameter and 5 mm in length). All electrochemical
measurements such as cyclic voltammetry (CV), constant-potential amperometry,
and electrochemical impedance spectroscopy (EIS) were performed with
a CHI 660E workstation (Shanghai Chenhua, China). Quartz crystal microbalance
with dissipation (QCM-D) measurements were performed with a Q-Sense
analyzer (Biolin Scientific) equipped with a MoS2-coated
sensor tip.
