Novel AgI/Ag 2 Mo 2 O 7 heterojunctions were prepared by reacting Ag 2 Mo 2 O 7 microrods with an aqueous KI solution at room temperature. The composite materials, compared with neat AgI and Ag 2 Mo 2 O 7 , showed much higher activities in the photocatalytic degradation of aqueous rhodamine B, methyl orange, tetracycline hydrochloride, and levofloxacin solutions under visible-light irradiation. The structures, morphologies, and other physicochemical properties of AgI, Ag 2 Mo 2 O 7 , and AgI/Ag 2 Mo 2 O 7 composites were studied via various characterization techniques. The active species involved in the photocatalytic process were examined via radical-capturing experiments and electron spin resonance. Superoxide anion radicals ( • O 2 – ) and photogenerated holes (h + ) were found to be the main active species. Photocatalytic mechanisms were proposed and reasons for the enhanced photocatalytic activity were explained.

“…The residual Ag in ULDNPGs might be oxidized to form AgCl during electrochemical dealloying or Ag 2 O after exposed to air. Both AgCl and Ag 2 O are photocatalytic semiconductors. , However, the XPS results (Figure S18) exclude this possibility. Therefore, the photodegradation property of ULDNPGs should originate from their plasmonic effects.…”

Plasmon-mediated chemical reaction has a great potential to create self-cleaning surface-enhanced Raman scattering (SERS) substrates. However, few works have been reported to promote this goal. Here, we report ultralow density nanoporous gold (ULDNPG) that possesses an impressive full spectrum responsive characteristic with a reflectivity lower than 5% in the waveband of 300–900 nm. ULDNPG was fabricated by a sandwich dealloying strategy from ultradilute Au–Ag solid solutions with the Au content as low as 1–5 at.%. The prepared ULDNPG presents excellent SERS properties, including high sensitivity, high uniformity, and reproducibility. The full spectrum responsive characteristic of ULDNPG leads to an obvious plasmonic photocatalytic activity. The short lifetime of the SP-excited hot carriers causes a restricted self-cleaning SERS property and a strong photothermal effect for ULDNPG structures.

“…Also, there are many different kinds of AgCl particles reported in the literature. It can be spherical, cubic and wire shapes, depends on the reaction conditions [24]. In this work, the AgCl synthetized has an irregular sphere-like phase with sizes about 2.5-7 μm [25,26].…”

In this work, a silver/silver chloride ink is fabricated using two steps. First the silver ink is prepare using silver, nail polish and acetone. Then the silver ink is painted in a paper substrate and a silver chloride layer is deposited using a bleach solution. The result is the silver/ silver chloride conductive ink. The silver ink is cheap ($2.49/g), well-dispersive and very easy to fabricate. The materials were characterized by SEM and XRD. The Ag ink showed the formation of a continuous network throughout the silver ink film with fewer agglomeration.The effective chlorination process was also observed in the Ag/AgCl characterization. Since the Ag/AgCl substrate will be used as a quasi-reference electrode, it is important to investigate the electrical properties. The Ag ink showed an average ohmic resistance of 2.27 Ω. The addition of the AgCl layer decreases the conductivity, as expected. In summary, the Ag/Ag/Cl ink developed is simple, well-dispersed, cheap and with good conductivity. Therefore, it can be used as a conductive ink in the fabrication of quasi-reference electrodes.
