Preparation and characterization of a novel modified system: polyaniline/1,5-naphthalene disulfonic acid as a novel photocatalyst for H2 production
The semiconducting properties of the system Polyaniline (PANI)/1,5-naphthalene disulfonic acid (NDSA) were investigated to assess its photocatalytic performance for the hydrogen evolution under visible light irradiation. PANI/NDSA is thermally stable up to ~ 300 °C, above which a weight loss of ~ 1....

| description | The semiconducting properties of the system Polyaniline (PANI)/1,5-naphthalene disulfonic acid (NDSA) were investigated to assess its photocatalytic performance for the hydrogen evolution under visible light irradiation. PANI/NDSA is thermally stable up to ~ 300 °C, above which a weight loss of ~ 1.2% occurs. The X-ray diffraction pattern showed broad peaks with a particle size of ~ 7 nm. A direct optical transition at 1.96 eV, was determined from the diffuse reflectance spectrum. The electrical conductivity of PANI/NDSA follow an exponential law with an activation energy of 0.24 eV. The
p
-type conduction was demonstrated from the (capacitance
−2
—potential) characteristic; a flat band potential (E
fb
) of 0.82 V
SCE
and a holes density (N
A
) of 8.43× 10
24
m

were determined in neutral solution (Na
2
SO
4
0.1 M). The electrochemical impedance spectroscopy, measured over an extended frequency domain (1 mHz—10
10
Hz), indicated the contribution of both the bulk and grain boundaries with a constant phase element (CPE). As application, PANI/NDSA was successfully tested for the hydrogen production under visible light owing to the potential of its conduction band (− 0.75 V
SCE
), more cathodic than that of H

O/H

(~− 0.30 V
SCE
). The H

liberation rate of 3840 µmol h
−1
(g catalyst)

and a quantum efficiency of 0.34% were obtained under full light (29 mW cm
−2
) using Fe(CN)

as reducing agent. The photoactivity was completely restored during the second cycle. |
