Bacillus thuringiensis Based Ruthenium/Nickel Co-Doped Zinc as a Green Nanocatalyst: Enhanced Photocatalytic Activity, Mechanism, and Efficient H₂ Production from Sodium Borohydride Methanolysis

Industrial & Engineering Chemistry Research, Journal Year: 2023, Volume and Issue: 62(11), P. 4655 - 4664

Published: Jan. 11, 2023

Today, the development of green nanocatalysts is among popular topics due to need for energy production and cleaning organic pollutants. In this approach, Bacillus thuringiensis, a bacterium, was used as biosupport ruthenium/nickel co-doped zinc nanoparticles (btRNZn NPs) release hydrogen from methanolysis sodium borohydride (NaBH4). addition, their photocatalytic activity reported against Methyl Orange (MO) dye. This study focused on preparation, characterization, catalytic btRNZn biocatalyst NaBH4 removal MO According TEM analysis, average size NPs found be 11.78 nm; in showed photodegradation effect 68.2% dye at 90 min, its mechanism discussed. The effects catalyst, substrate, temperature reaction presence catalyst were investigated extensively. kinetics calculated, TOF, activation energy, enthalpy measured 2497.14 h–1, 14.89 kJ/mol, 12.35 respectively. It observed that process first-order based amount substrate. aimed synthesize nanobiocatalyst by biological method, it will great photocatalyst prevent wastewater pollution; also, can an excellent produce methanolysis. application solar photocatalysis pollution research through creation are both made clear these studies.

A pragmatic review on photocatalytic degradation of methyl orange dye pollutant using greenly biofunctionalized nanometallic materials: A focus on aquatic body

Applied Organometallic Chemistry, Journal Year: 2023, Volume and Issue: 37(7)

Published: April 20, 2023

Water is the source of life. But unfortunately, 80% wastewater discharged into aquatic body untreated globally, which industry responsible for 70% such water abstraction through discharge pollutants like methyl orange. According to WWAP, pollution kills 100 million individuals, 2 marine animals, and seabirds yearly, by 2025, it forecasted that ~1000 inhabitants in arid zones will experience severe crisis, thus, security has become focal outcry due daily environmental escalation caused rapid growth industries population. Recently, biosynthesized nanoparticles as photocatalysts have answered call sustainable treatment orange dye effluent photodegradation because their efficient photoactivity, inexpensiveness, eco‐benignness. In this review, photocatalytic‐degradation mechanism pathways environment presence • OH − O using green were mechanistically discussed. The highest degradation efficiency was found be 100%, final mineralization products H CO , least time taken min with silver being most commonly used degrader plant extracts employed bioreductant biosynthesis nanoparticles.
