Description

General description

Heterogeneous ozonolysis of naphthalene adsorbed on XAD-4 resin has been studied using annular denuder technique[1].

Application

Naphthalene was used in liquid-phase exfoliation of graphite in organic solvents for the production of graphene sheets[2]. It was used in preparation of carbon-coated Si₇₀Sn₃₀ nanoparticles[3]. It was used as fluorescent probe to study the aggregation behavior of sodium cholate[4].
