Resumen:
oth layered double hydroxides (LDHs) and Zn layered hydroxide salts (LHSs) are intercalation compounds
with potential applications as pollutant sorbents and antimicrobial, drug, and pesticide carriers,
among others. Their reactivity and interfacial properties are essential to these applications and dependent
on the layer structure and interlayer anion nature. In this work, the structure and bonding of Zn?Cr
LDHs and Zn LHSs intercalated with chloride, 4-chlorobenzoate, and 4-chlorobenzylsulfonate were analyzed
using X-ray diffraction and infrared spectroscopy. Afterwards, their effect on interfacial properties
and reactivity was assessed by zeta potential measurements, contact angle determinations, and hydroxide
anions uptake. Due to their different structure, LDHs presented electrostatic interactions between
their layers and the intercalated anions, while LHSs portrayed coordinated binding. The latter exhibited
neutrally or negatively charged particles and ligand exchange re
