“…[38] Abed et al synthesized DyCrO 3 -rGO through hydrothermal method for photocatalytic dye degradation and hydrogen production. [39] The particular class of rare earth perovskite oxides are still unexplored and not harnessed fully to their potential. Hence, in this paper, we demonstrated the fabrication of multiferroic DyCrO 3 nanoparticles using low temperature reverse micellar route [40,41] which remarkably acts as bifunctional photo and electrocatalyst and show significant amount of photocatalytic hydrogen production.…”

Herein, we demonstrate photocatalytic hydrogen generation and the role of sacrificial agents using multifunctional DyCrO 3 nanoparticles by virtue of built-in electric field (BIEF) which helps in increasing charge separation efficiency. DyCrO 3 nanoparticles synthesized by the low-cost reverse micellar approach showed high surface area (17.9 m 2 / g) and band-gap (2.01 eV) in visible region. Sacrificial agent assisted photocatalytic H 2 production of DyCrO 3 nanoparticles exhibited higher selectivity towards Na 2 S/Na 2 SO 3 by produc-ing H 2 evolution of 347 μmol h À 1 g À 1 cat and apparent quantum yield of 6.8% than ethylene glycol and triethanolamine, respectively. The oxygen defects (observed in X-ray photoelectron spectroscopic studies) and BIEF both synergistically helped in enhancing photocatalytic activity. Moreover, the multifunctional competence of DyCrO 3 nanoparticles was observed in electrocatalytic water splitting. DyCrO 3 nanoparticles found to be active HER and OER electrocatalyst with low overpotential and great durability.

Recently, design and fabrication of electrochemical sensors have received huge attention because of their high sensitivity, cost-effectiveness, good selectivity, simple processing, and low detection limit. Herein, we have fabricated zinc oxide (ZnO) hexagonal plates/reduced graphene oxide (rGO) composite under benign approach. Different characterization techniques and approaches such as XRD, SEM, EDX, UV-vis, and XPS were utilized to authenticate the formation and phase purity of ZnO/ rGO composite. Further, we have modified active surface area (3 mm) of bare glassy carbon electrode using ZnO/rGO as electro-catalyst (electrode material) for the construction of nitrite sensor. This modified electrode (ZnO/rGO/GCE) demonstrated low-limit of detection (DL) of 0.1 μM with good sensitivity of 2.47 μA/μMcm 2 . Moreover, fabricated ZnO/rGO/ GCE exhibited excellent selectivity, stability and repeatability towards the detection of nitrite. Additionally, ZnO/rGO was also applied as photo-catalyst towards photo-catalytic hydrogen (H 2 ) generation. The ZnO/rGO showed good H 2 generation rate of 650.3 μmolg À 1 h À 1 compared to the pristine rGO or ZnO.
