Silver Zirconate: A robust material for supercapacitor application, photocatalytic water splitting and photoactivation of persulfate ion for environmental remediation
INTERNATIONAL JOURNAL OF HYDROGEN ENERGY(2024)
摘要
Herein, we report the facile synthesis of silver zirconate (Ag2ZrO3) via the co-precipitation method. The assynthesized Ag2ZrO3 is employed for diversified applications viz. EOSIN Y dye-sensitized photocatalytic hydrogen production under visible light irradiation, supercapacitor application, and photoactivation of persulfate (PS) ions for decontamination of model organic pollutant (RhB). The as-synthesized Ag2ZrO3 with EOSIN Y (EY) exhibits excellent photocatalytic water splitting efficiency for hydrogen production (2288.94 mu molg-1) in just 4 h of visible light irradiation. The supercapacitor study reveals that the maximum energy density for the Ag2ZrO3 electrode is 53.2 Whkg- 1 at a scan rate of 10 mVs- 1. Additionally, Ag2ZrO3 also exhibits almost 100% RhB (2.1 x 10-5 M) dye degradation in just 90 min of visible light irradiation in the presence of PS. These abovementioned applications of Ag2ZrO3 will open new avenues for a wide range of energy and environmental applications.
