Photocatalytic degradation performance of a chitosan/ZnO-FeO nanocomposite over cationic and anionic dyes under visible-light irradiation.

The sonochemical synthesis of a chitosan-ZnO/FeO nanocomposite yielded a highly porous structure and large surface area for enhancing the photocatalytic degradation of cationic (rhodamine B, RhB) and anionic (methyl orange, MO) dyes in aqueous solution. Chitosan-ZnO/FeO demonstrated a significant enhancement in photodegradation efficiency 99.49% for MO ( = 5.

Determinants of Environmental Pollution in China: Novel Findings from ARDL Method.

This study examines how EC, FF use, RC, POP growth, trade, GDP, and CO emissions are interrelated in China. It aims to clarify how these factors together impact environmental pollution and economic sustainability. The motivation stems from China's dual challenge of sustaining economic growth while mitigating environmental degradation, particularly CO emissions.

Factors affecting carbon dioxide emissions for sustainable development goals - New insights into six asian developed countries.

The worldwide economic scene faces the dual challenges of rising sea levels and escalating carbon dioxide (CO2) emissions. Environmental contamination impedes sustainable growth, increasing the demand for sustainable energy resources as a fundamental aspect of sustainable economies. The present research uses an analytical model to examine the elements influencing carbon dioxide output in six economically developed Asian nations, intending to assist in realizing the UNSDG- United Nations' Sustainable Development Goals.

Factors Affecting Renewable Energy for Sustainable Development: The Case of the Philippines.

This paper examines the nexus between carbon dioxide (CO) emissions, electricity consumption, fossil fuels, foreign direct investment (FDI), gross domestic product (GDP), and renewable energy in the Philippines. This paper also explores the intricate relationships between carbon dioxide (CO) emissions, electricity consumption, fossil fuel use, foreign direct investment (FDI), gross domestic product (GDP), and renewable energy in the Philippines. Utilizing time-series data from 1990 to 2022 and applying advanced econometric techniques such as vector error correction modeling (VECM) and Granger causality tests, the study reveals the significant impacts of economic growth and energy consumption on CO emissions.

High photocatalytic efficiency of a ZnO nanoplate/FeO nanospindle hybrid using visible light for methylene blue degradation.

In this work, ZnO nanoplates and FeO nanospindles were successfully fabricated a simple hydrothermal method using inorganic salts as precursors. The ZnO/FeO hybrid was fabricated using a mechanical mixture of two different ZnO : FeO weight ratios to investigate the effect of weight ratio on catalytic properties. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) images showed that ZnO nanoplates (NPls) are about 20 nm thick with lateral dimensions of 100 × 200 nm, and FeO nanospindles (NSs) are about 500 nm long and 50 nm wide.
