Cover Story: Several industries use azo dye to treat food, textiles, and pharmaceutics. Still, due to their presence of azo bonds, harmful effects are impacted upon ingestion since the bond cleavage forms aromatic amines that are carcinogenic and can harm aquatic organisms. The main aim of this study is to understand the photocatalysis of Methyl orange using the silver nanoparticle synthesized by the extracts of five Cucurma species leaves. Photocatalysis of methyl-orange by all AgNPs was achieved with NaBH4 while 4000 ppm AgNPs showed greater photocatalysis with the addition of NaBH4. View this paper.

Exploration of Molybdenum Oxide Compounds-A Review

Received: 17 February 2024;  Published: 09 August 2024;  doi: 10.21926/cr.2403011

Abstract

The evolution of nanomaterials has been critical in modifying materials at the nanoscale for specialized uses. Carbon nanotubes were initially viewed as promising for electronics, but their inability to discriminate between semiconducting and metallic phases led to the creation of quasi-two-dimensional (Q-2D) materials. Molybdenum nanoparticles are utilized as alloy additions in corrosive and high-vacuum environments. Their characteristics differ significantly [...]

Leaf Mediated Curcuma sp. Silver Nanoparticles as Catalyst - Evaluating Their Antioxidant, Cytotoxicity, Para-Nitrophenol Catalytic and Photocatalytic Activity

Received: 29 April 2024;  Published: 22 July 2024;  doi: 10.21926/cr.2403010

Abstract

Nanotechnology is a fast-rising market in catalytic research; however, the production of eco-friendly nanoparticles remains a significant challenge. In this study, silver nanoparticles (AgNPs) were synthesized from the agro-industrial waste of leaves of C. longa, C. aromatica, C. caesia, C. zedoaria, and C. amada at RT after 24 h, which was confirmed with UV-spectrophotometric evaluation betwe [...]

Kinetic Model for the Hydrolysis of Olive Oil by Lipase in Absence of Emulsifier

Received: 27 March 2024;  Published: 18 July 2024;  doi: 10.21926/cr.2403009

Abstract

Lipase-catalyzed hydrolysis of olive oil has been studied in the absence of emulsifier. A simple mathematical model to predict the hydrolysis rate is derived from a proposed kinetic mechanism of the reaction. The hydrolytic reaction obeys Michaelis-Menten kinetics with a simultaneous second-order enzyme deactivation. The model predictions closely agree with the experimental results.

Effective Photogeneration of Singlet Oxygen and High Photocatalytic and Antibacterial Activities of Porous Mn-Doped ZnO-ZrO2 Nanocomposites

Received: 06 April 2024;  Published: 03 July 2024;  doi: 10.21926/cr.2403008

Abstract

Disperse porous Mn-doped ZnO-ZrO2 nanocomposites were prepared using the facile polymer-salt method. The effect of Mn content on the crystal structure, composite morphologies, their ability to photogenate the singlet oxygen, luminescence properties, and bactericidal activities were studied. The crystal structure and morphology of these materials were investigated using XRD and SEM analysis. It was found that obtained nanocomposites consist of small (~9 nm) hexagonal ZnO an [...]

Determination of Reflectance Spectra and Colorimetry of Titanium and Tungsten Oxides Obtained by Microwave-assisted Hydrothermal Synthesis

Received: 04 February 2024;  Published: 01 July 2024;  doi: 10.21926/cr.2403007

Abstract

Sustainability has driven the use of heterogeneous photocatalysis as one of the primary methods for environmental decontamination, reduction, degradation, remediation, or transformation of polluting chemical residues and purification treatment of effluents and wastewater. TiO2 is the most commonly used semiconductor in heterogeneous photocatalysis. It acquires relevance, as it has favorable properties, such as non-toxicity, stability in a wide range of pH, economic viabili [...]
