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 from those of their bulk counterparts. This review anal [...]

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 between 320-520 nm. SEM revealed cubic and 30-50 nm AgNPs, while band-gap energy was presented as semi-conductors. Synthesized Ag [...]

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 and fine ZrO2 crystals and the embedding of M [...]

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 viability, etc., which encourage its application a [...]

llmenite and Biomass Composite Nanomaterials - A Review

Received: 10 April 2024;  Published: 13 June 2024;  doi: 10.21926/cr.2402006

Abstract

Ilmenite is a mineral whose crystallinity can be altered by chemical treatment, producing TiO2 and iron and titanium-based metal nanocomposites, which are applicable mainly for photocatalysis. Porous and crystalline biomass-derived carbon materials include graphene oxide, reduced graphene oxide, graphitic carbon nitride, catalytically graphitized sucrose and chitosan, and activated carbon. Ilmenite-based metal oxides coupled with biomass-based carbon materials are effective in environmental remediation, especially [...]

A Remarkable Pt Doped CNT Catalyst as a Double Functional Material: Its Application for Hydrogen Production and Supercapacitor

Received: 25 December 2023;  Published: 15 May 2024;  doi: 10.21926/cr.2402005

Abstract

In this study, by producing bifunctional material, hydrolysis, and supercapacitor applications were investigated. The carbon nanotube-supported Pt catalyst was prepared using the sodium borohydride (NaBH4) reduction. Surface characterization of the synthesized Pt/CNT catalyst was performed using scanning electron microscopy-energy dıstrıbutıon X-ray spectrometer (SEM-EDX), X-ray diffraction (XRD), and transmission electron microscopy (TEM). Hydrolysis experiments were performed after deciding on the appropriate ato [...]
