Visible‐Light Tempted Photocatalytic Activity of Newly Synthesized Co₃O₄NiOPdOPd Nanomaterial for Removal of Azo Dyes

AbstractTo contribute to the development of sustainable and effective nano‐catalyst for dye degradation is greatly enviable to solve the global environmental remediation problems. In this regard, here facile Co3O4NiOPdOPd nanomaterial was synthesized via phyto‐organic fuel and scrutinized as nanocatalyst to degrade methyl orange (MO). The Co3O4NiOPdOPd nanomaterial was synthesized following the sol gel synthesis methodology using foliar phyto extract of Abies pindrow Royle leaves. The synthesized nanomaterial of Co3O4NiOPdOPd was studied by X‐rays diffraction, Raman spectroscopy, Energy‐dispersive spectroscopy, as well as Field‐emission scanning electron microscopy. Fourier transform infrared spectroscopy, Gas chromatography and Mass spectrometry. The facile bio nanomaterial was studied for removal of MO both under sunlight and under dark. Fabricated nanocatalyst of mixed metal oxides (MMO) exhibited the degradation efficiency of 95 % in the presence of sunlight and 85 % without sunlight (in dark condition) in 15 minutes.The comparison of catalytic potential of MOD‐L and MOD‐D for Co3O4−NiO−PdO−Pd for 2 minutes exhibited maximum degradation percent MOD‐L (72.2.4 %) followed by MOD‐D (51.5 %). However, after 20 minutes MOD‐L exhibited higher percentage of 95.4 % while MOD‐D revealed 84.8 percent degraded MO. Consequently, the nano‐scale features have enhanced the catalytic performance of Co3O4NiOPdOPd photocatalyst towards water purification from organic pollutants.
